Perianal Paget 's disease complicated with lung adenocarcinoma and anal canal carcinoma: A case report and literature review / 中南大学学报(医学版)

Perianal Paget's disease (PPD) is a rare malignant cutaneous tumor. This paper reported a case of PPD complicated by lung adenocarcinoma and anal canal cancer. The patient, a 76-year-old female, had been experiencing recurrent lower abdominal pain and perianal pruritus for the past 5 years. Upon physical examination, a cauliflower-like neoplasm in size of 5 cm×6 cm was observed on the right perianal skin, with local skin ulceration and a small amount of fluid discharge. The left perianal skin was also involved. In thoracoknee position, a hard mass was palpable in the rectal submucosa at 5-6 points 2 cm from the anal verge. Chest CT revealed multiple lesions in both lungs, indication of metastatic tumors. Further evaluation with fluorodeoxyglucose positron emission tomography and computed tomography (FDG-PET/CT) indicated multiple hypermetabolic nodules in the lungs, hypermetabolic lymph nodes throughout the body, early FDG uptake in a small patch of skin on the left hip, and increased FDG uptake in the anorectal region. Histopathological examination confirmed the diagnosis of lung adenocarcinoma. This resulted in the patient being diagnosed with PPD, lung adenocarcinoma, anal canal cancer, and systemic multiple lymph node metastasis. The combination of PPD with gastrointestinal tumors and other metachronous malignant tumors is highly prevalent. Colonoscopy, FDG-PET/CT, histopathology, and immunohistochemistry play crucial roles in early identification of local lymph node and distant involvement, facilitating the evaluation of potential malignant tumors and differential diagnosis. Treating methods for PPD are currently diverse, including postoperative combined or single chemotherapy, radiotherapy, targeted therapy, and photodynamic therapy. As trerapeutical options continue to develop, the extent and efficacy of surgery need to be reassessed.

Bipedicled scrotal flaps combined with keystone-design perforator island flaps in repairing postoperative large-area defects in 6 male patients with extramammary Paget′s disease of the perineum / 中华皮肤科杂志

Objective:To evaluate clinical efficacy of bipedicled scrotal flaps combined with keystone-design perforator island flaps in repairing postoperative large-area defects in male patients with extramammary Paget′s disease of the perineum.Methods:Clinical data were collected from 6 male patients with extramammary Paget′s disease of the perineum in Dermatology Hospital of Jiangxi Province from February 2018 to March 2019, and analyzed retrospectively. These patients were aged from 70 to 84 years (median, 77.5 years) , skin lesions involved the mons pubis, penis and scrotum, and the area of postoperative skin defects varied from 18 to 133 cm 2 (median, 96 cm 2) in size. In all the patients, mons pubis defects after tumor resection were repaired with abdominal keystone-design perforator island flaps, and scrotal and penile defects were repaired with bipedicled scrotal flaps using the remaining scrotal tissues. These patients were followed up at 1 and 3 months after surgery and every 3 months thereafter. Results:All the 6 patients were followed up for 3 - 36 months, with an average of 10 months. All flaps survived with a good color and texture match, and favorable function and appearance were achieved in both the donor and recipient sites.Conclusions:The bipedicled scrotal flaps combined with keystone-design perforator island flaps can repair postoperative large-area defects in male patients with extramammary Paget′s disease of the perineum. Moreover, the operation is simple, and good blood supply can be achieved.

Advances in the treatment of extramammary Paget disease / 国际肿瘤学杂志

Extramammary Paget disease (EMPD) is a kind of rare clinical malignant tumor in the skin. Surgical treatment is the main treatment method, and the Mohs microsurgery is considered the first choice which can control the incision margin accurately and reduce the recurrence rate. Due to the insidious and multifocal nature of the disease, the postoperative recurrence rate is still high. The other treatment methods include radiation therapy, chemotherapy, targeted therapy, photodynamic therapy, local drug therapy and laser therapy. Further research on the progress of EMPD treatment is helpful for the management and treatment of patients in clinical practice.

Enfermedad de Paget pigmentada de la mama simuladora de melanoma cutáneo / Pigmented mammary Paget's disease mimicking cutaneous melanoma

Resumen ANTECEDENTES: La enfermedad de Paget pigmentada de la mama es una variante poco frecuente de este padecimiento cutáneo, una dermatosis que afecta al complejo areola-pezón de manera típicamente unilateral. La importancia del reconocimiento de esta dermatosis pigmentada inespecífica es que forma parte del diagnóstico diferencial del melanoma cutáneo, por manifestarse como una mácula pigmentada irregular, cuyo estudio histopatológico muestra una proliferación de melanocitos en los estratos suprabasales de la epidermis, fagocitosis de melanina y melanófagos en dermis, hallazgos muy similares al melanoma cutáneo, además de la coexistencia de células claras malignas, características de la enfermedad de Paget. La inmunohistoquímica es una técnica auxiliar en la dermatopatología, que forma parte del proceso diagnóstico de los pacientes para lograr el diagnóstico certero que, al correlacionar la clínica y el estudio histopatológico, le permite al dermatólogo tratar a los pacientes con enfermedad de Paget pigmentada de la mama junto con un equipo multidisciplinario para la búsqueda, diagnóstico y, en su caso, tratamiento quirúrgico de las neoplasias subyacentes que suelen relacionarse con esta variante pigmentada. CASO CLÍNICO: Paciente de 35 años con una lesión pigmentada que afectaba el complejo areola-pezón derecho. Con la correlación histopatológica e inmunohistoquímica se estableció el diagnóstico de enfermedad de Paget pigmentada de la mama y posterior al procedimiento ginecológico, se asoció esta dermatosis con un adenocarcinoma microinvasor triple negativo. CONCLUSIONES: La enfermedad de Paget pigmentada de la mama es un diagnóstico complejo que requiere correlación clínico-patológica y estudios de extensión para valorar su asociación con neoplasias subyacentes.

Abstract BACKGROUND: Pigmented Mammary Paget's Disease is a rare variant of this skin condition, an unilateral dermatosis that typically affects the areola-nipple complex. The importance of recognizing this nonspecific pigmented dermatosis resides in its differential diagnosis of cutaneous melanoma, as it presents as an irregular pigmented macula. The histopathological study shows proliferation of melanocytes in the suprabasal layers of epidermis, phagocytosis of melanin and melanophages in dermis. These findings are very similar to cutaneous melanoma, in addition to the presence of malignant clear epitelial cells that are characteristic of Paget's disease. Immunohistochemistry is part of the approach of patients with lesions that shows proliferating melanocytes to rule out other neoplasms. Making an accurate diagnosis by correlating the clinical, histopathological study and immunohistochemistry allows the dermatologist to approach patients with mammary pigmented mammary Paget's disease with a multidisciplinary team for the diagnosis and surgical treatment of the underlying neoplasms that are usually related to this pigmented variant. CASE REPORT: We report the case of a 35 years old woman with a pigmented lesion that affected the right areola-nipple complex. With the histopathological and immunohistochemical correlation, the diagnosis of pigmented mammary Paget's disease was made and after the gynecological approach, this dermatosis was associated with a triple negative microinvasive adenocarcinoma. CONCLUSION: Pigmented mammary Paget's disease is a complicated diagnosis that requires clinicopathological correlation and extension studies to assess its association to underlying neoplasms.

Clinical features, diagnostic evaluation and responses to treatment in Paget's disease of bone in a center specialized in bone metabolism / Características clínicas, evaluación diagnóstica y respuestas al tratamiento de la enfermedad de Paget ósea en un centro especializado en metabolismo óseo

Abstract The epidemiology of Paget's disease of bone (PDB) has changed in the last years but there is no update data on its clinical presentation, diagnosis and management in Latin America. Our aim was to describe its clinical features, diagnostic evaluation and responses to treatment in a group of PDB patients treated between June 2012 and December 2019 in an institution specialized in bone diseases, in Buenos Aires, Argentina. The frequency of PDB (180/10 714) was 1.68%. Median age was 67 (range 39-97) years and 59.5% were women. Most patients were asymptomatic (58.6%) and had monostotic disease (54.3%). Favorable responses were obtained in all patients who were treated with zoledronate (n = 36), in 10 out of 14 treated with pamidronate, in 9 out of 10 who received intravenous ibandronate and in 12 out of 13 who received oral bisphosphonates. The response rates were not significantly different when we compared monostotic vs. polyostotic disease. Among the biochemical parameters, mean values of bone specific and total alkaline phosphatase, and C-terminal cross-linked telopeptide of type I collagen decreased significantly after treatment with bisphosphonates. It seems that our results reflect the change in PDB epidemiology towards a more indolent disease. In the future, this would probably allow physicians to use lower doses of bisphosphonates than the ones historically recommended for these patients.

Resumen La epidemiología de la en fermedad de Paget ósea (EPO) ha cambiado en los últimos años. Son necesarios datos actualizados sobre su forma de presentación clínica, diagnóstico y tratamiento en nuestra región. Nuestro objetivo fue describir las características clínicas, evaluación diagnóstica y respuestas al tratamiento de un grupo de pacientes con EPO en un centro especializado en salud ósea de Buenos Aires, Argentina. Se evaluaron todos los pacientes que fueron atendidos en nuestra institución por enfermedades óseas entre junio de 2012 y diciembre de 2019. La frecuencia de EPO (180/10 714) fue de 1.68%. La mediana de edad fue de 67 (rango 39-97) años. El 59.5% eran mujeres. La mayoría se encontraba asintomático (58.6%) y tenían enfermedad monostótica (54.3%). Se objetivaron respuestas favorables en todos los que recibieron zoledronato (n = 36), en 10 de 14 pacientes que recibieron pamidronato, en 9 de 10 que utilizaron ibandronato endovenoso y en 12 de 13 con bifosfonatos orales. Los porcentajes de respuesta no variaron significativamente entre pacientes con formas monostóticas y poliostóticas. Entre los parámetros bioquímicos, los valores de fosfatasa alcalina total y ósea y de β cross-laps disminuyeron significativamente luego del tratamiento con bifosfonatos. Nuestros resultados reflejarían un cambio en la epidemiología de la EPO hacia una forma de presentación más indolente. Esto permitiría probablemente el uso de dosis más bajas de bifosfonatos que las históricamente recomendadas para estos pacientes.

Young mammary Paget's disease patients with underlying breast invasive ductal carcinoma: clinicopathological features and prognosis / 中华肿瘤杂志

Objective: To investigate the clinicopathological factors and prognostic status of young Mammary Paget's disease (MPD) patients with invasive ductal carcinoma (IDC). Methods: In this study, we defined the age at diagnosis below 40 years old as young patients, and retrospectively analyzed data from 123 MPD-IDC patients who were admitted at the Cancer Hospital Chinese Academy of Medical Sciences from June 2002 to February 2019. Patients were divided into the young group (≤40 years old, 15 cases) and the old group (>40 years old, 108 cases) according to the age of onset, and the clinicopathological characteristics and prognosis of the two groups were compared. Cox regression model analysis was used to analyze the prognosis influencing factors. Results: The proportions of patients in the young group with non-menopausal, axillary lymph node metastasis, and Ki-67 index ≥15% were 93.3% (14/15), 73.3% (11/15), and 86.7% (13/15), respectively, which were higher than those in the old group [45.4% (49/108), 39.8%(43/108), and 60.2% (65/108), respectively] , with statistically significant differences (P<0.05). At an average follow-up of 63.2 months, patients in the young group had a significantly shorter disease-free survival (DFS) compared with that of the old group (P=0.012), while the difference in overall survival (OS) between the two groups was not statistically significant (P=0.161). Multifactorial Cox regression analysis showed that axillary lymph node status was an independent influencing factor on OS (HR=3.339, 95% CI: 1.121-9.943) in patients with MPD-IDC, while age was not. Conclusion: Compared with the old group, young patients with MPD-IDC have a higher incidence of axillary lymph node metastasis, high Ki-67 expression, and a shorter DFS, but age is not an independent influencing factor on DFS or OS in patients with MPD-IDC.

Surgical management of nipple areola complex in central breast cancer / 中华肿瘤杂志

Objective: To explore the surgical strategy of nipple areola complex (NAC) management in central breast cancer. Methods: A retrospective analysis was conducted on 164 cases of central breast cancer who underwent surgery treatment from December 2017 to December 2020 in the Breast Center of Beijing Tongren Hospital, Capital Medical University. Prior to the surgery, the tumor-nipple distance (TND) and the maximum diameter of the tumor were measured by magnetic resonance imaging (MRI). The presence of nipple invagination, nipple discharge, and nipple ulceration (including nipple Paget's disease) were recorded accordingly. NAC was preserved in patients with TND≥0.5 cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative intraoperative frozen pathological margin. All patients with signs of NAC involvement, TND<0.5 cm or positive NAC basal resection margin confirmed by intraoperative frozen pathology underwent NAC removal. χ(2) test or Fisher exact test was used to analyze the influencing factors. Results: Of the 164 cases of central breast cancer, 73 cases underwent breast-conserving surgery, 43 cases underwent nipple-areola complex sparing mastectomy (NSM), 34 cases underwent total mastectomy, and the remaining 14 cases underwent skin sparing mastectomy (SSM). Among the 58 cases of NAC resection (including 34 cases of total mastectomy, 14 cases of SSM, and 10 cases of breast-conserving surgery), 25 cases were confirmed tumor involving NAC (total mastectomy in 12 cases, SSM in 9 cases, and breast-conserving surgery in 4 cases). The related factors of NAC involvement included TND (P=0.040) and nipple invagination (P=0.031). There were no correlations between tumor size (P=0.519), lymph node metastasis (P=0.847), bloody nipple discharge (P=0.742) and NAC involvement. During the follow-up period of 12 to 48 months, there was 1 case of local recurrence and 3 cases of distant metastasis. Conclusions: For central breast cancer, data suggest that patients with TND≥0.5cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative NAC margin in intraoperative frozen pathology should be treated with NAC preservation surgery, whereas for those with TND<0.5 cm or accompanied by signs of NAC invasion, NAC should be removed. In addition, nipple reconstruction can be selected to further improve the postoperative appearance of patients with central breast cancer.

Enfermedad de Paget bilateral de la mama. Presentación inusual de un caso

RESUMEN La enfermedad de Paget de la mama se encuentra entre las llamadas formas especiales del cáncer de mama. Su incidencia es de solo el 1 al 1,5 % del total de los cánceres mamarios que se diagnostican. Fundamentalmente aparece en mujeres en la quinta o sexta décadas de la vida. Se considera extremadamente rara en su forma bilateral. Se presenta el caso de una paciente de 32 años de edad que acudió a consulta provincial de mastología por presentar lesiones escamosas en el complejo areola pezón de ambas mamas, más acentuadas en la derecha. Se le realizó biopsia con aspiración con aguja fina y se diagnostica enfermedad mamaria de Paget bilateral. La enfermedad de Paget de la mama es una enfermedad de rara aparición y en el caso que se presenta aparecen dos características pocos comunes, el tratarse de una paciente joven y la localización bilateral de la enfermedad, lo cual hace de más valor su publicación para conocimiento del personal médico dedicado a la atención de estas afecciones.

ABSTRACT Paget's disease of the breast is among the so-called special forms of breast cancer. Its incidence is only 1 to 1.5 % of all breast cancers that are diagnosed. It mainly appears in women in the fifth or sixth decade of life. It is considered extremely rare in its bilateral form. The case of a 32-years-old female patient of urban origin who attended the provincial mastology clinic for presenting scaly lesions in the nipple areola complex of both breasts, more accentuated on the right side. She underwent a fine needle aspiration biopsy and was diagnosed with bilateral Paget's disease of the breast. Paget's disease of the breast is a disease of rare appearance throughout the world and in the case that it occurs, two uncommon characteristics appear, the fact that it is a young patient and the bilateral location of the disease, which makes it more valuable its publication for the knowledge of medical personnel dedicated to the care of these conditions.

Enfermedad de Paget extramamaria perianal, tratada con imiquimod tópico / Atypical presentation of perianal extramammary Paget's disease, treated with topical imiquimod

RESUMEN La enfermedad de Paget extramamaria (EPEM) perianal es un adenocarcinoma intraepitelial del margen anal de muy baja frecuencia. La forma primaria representa una neoplasia de origen apocrino, mientras que la forma secundaria representa una diseminación pagetoide de una neoplasia maligna en general anorectal. Debido a su similitud clínica con otras patologías de presentación frecuente, se requiere de un alto índice de sospecha para diagnosticarla. La resección quirúrgica amplia o la cirugía micrográfica de Mohs se considera comúnmente el pilar del tratamiento con altas tasas de recurrencia. Estudios previos han demostrado buena respuesta en la EPEM vulvar con imiquimod 5% en crema, pero su eficacia no ha sido bien descrita en la afectación perianal. En este artículo presentamos un caso de EPEM perianal primario con sobreinfección con HPV, al que se le indicó tratamiento tópico con imiquimod.

ABSTRACT Perianal extramammary Paget disease is a very low frequency intraepithelial adenocarcinoma of the anal margin. The primary form represents a neoplasm of apocrine origin, while the secondary form represents a pagetoid spread of a generally anorectal malignant neoplasm. Due to its clinical similarity with other pathologies with frequent presentation, a high index of suspicion is required to diagnose it. Wide surgical resection or Mohs micrographic surgery is commonly considered the mainstay of treatment with high recurrence rates. Previous studies have shown a good response in vulvar extramammary Paget disease with imiquimod 5% cream, but its efficacy has not been well described in perianal involvement. In this article we present a case of primary perianal extramammary Paget disease with HPV superinfection, which received topical treatment with imiquimod.

El objetivo es revisar los aspectos fundamentales clínicos, diagnósticos, así como los avances más recientes en su tratamiento. Se realizó una búsqueda bibliográfica a través de PUBMED, GOOGLE SCHOLAR y UPTODATE, de los últimos 20 años. Fueron seleccionados e incluidos en la revisión 38 artículos. La enfermedad de Paget mamaria es una neoplasia maligna infrecuente del complejo areola pezón de características inflamatorias al examen físico, asociado en un 85% de los casos a un cáncer de mama subyacente, en el 50% de los casos no identificable al examen físico, de difícil diagnóstico, cuya sospecha clínica se confirma con imágenes, biopsia e inmunohistoquímica. El tratamiento es mastectomía versus cirugía conservadora y radioterapia. Un mal enfoque clínico, retrasa el diagnóstico y empeora la sobrevida. MÉD.UIS.2021;34(1): 45-53.

Abstract Paget's disease of the breast is an uncommon neoplasm of the breast, many times difficult to diagnose and of poor prognosis. The objective is to review the fundamental clinical and diagnostic aspects, as well as the most recent advances in its treatment. A bibliographic search of the last 20 years was carried out through PUBMED, GOOGLE SCHOLAR and UPTODATE. 38 articles were selected and included in the review. Mammary paget disease is a rare malignant neoplasm of the nipple areola complex with inflammatory features on physical examination, associated in 85% of cases with underlying breast cancer, in 50% of cases not recognizable on physical exam, difficult to diagnose, whose clinical suspicion is confirmed by imaging, biopsy and immunohistochemistry. Treatment is mastectomy versus conservative surgery and radiotherapy. A poor clinical approach delays the diagnosis and worsens survival rate. MÉD.UIS.2021;34(1): 45-53.

Reflectance confocal microscopy-assisted surgical treatment for two cases of extramammary Paget′s disease of the vulva / 中华皮肤科杂志

In order to develop a method to more accurately determine the surgical boundary of extramammary Paget′s disease, reflectance confocal microscopy was used to determine the tumor boundary followed by modified extended excision in 2 cases of pathologically diagnosed extramammary Paget′s disease of the vulva. No residual tumor was observed in the resection margins by postoperative pathological examination at 4 positions (12, 3, 6 and 9 o′clock) , and follow-up showed no recurrence 1 year later.

Analysis of high-frequency color Doppler ultrasound characteristics of extramammary Paget′s disease / 中华皮肤科杂志

Objective:To explore high-frequency color Doppler ultrasound characteristics of extramammary Paget′s disease (EMPD) .Methods:From January 2015 to October 2019, 32 patients with pathologically confirmed EMPD were collected from the Affiliated Hospital of Jining Medical University, and characteristics of their high-frequency color Doppler ultrasound images were retrospectively analyzed.Results:Of the 32 lesions, 25 were located on the external genitalia (21 on the scrotum, 4 on the perineum) , 4 on the medial thigh, 1 on the lower abdominal wall, 1 in the perianal region, and 1 on the neck. Ipsilateral inguinal lymph node metastasis occurred in 3 patients, and bilateral inguinal lymph node metastasis in 1 patient. High-frequency ultrasonography showed no obvious abnormal ultrasound manifestations in 6 cases, and thickened skin lesions in 26 cases. According to the morphological and high-frequency ultrasound manifestations, 26 skin lesions were classified into 2 types: 21 diffuse-type lesions with unclear borders and irregular shapes, and 5 mass-type lesions with clear borders and irregular shapes. Solid and homogeneously hypoechoic areas were observed in 18 cases, and solid and heterogeneously hypoechoic areas in 8. According to the Adler blood flow classification, the 26 lesions were classified into 4 grades: 2 of grade 0, 5 of grade 1, 8 of grade 2, and 11 of grade 3.Conclusion:EMPD shows characteristic high-frequency color Doppler ultrasound manifestations, which can facilitate its clinical diagnosis.

A case of occult malignancies with disseminated carcinomatosis of the bone marrow presenting with isolated elevation of serum alkaline phosphatase / 中华内分泌代谢杂志

The measurement of serum alkaline phosphatase (ALP) levels has been widely used in the clinical setting. However, isolated elevation of serum ALP levels is also commonly seen and needs to be extensiuely evaluated Herein, we present a case of gastric adenocarcinoma with disseminated carcinomatosis of the bone marrow (DCBM). In this case, isolated elevation of serum ALP levels was the only clinical manifestation with no other notable symptom. Additionally, imaging studies including whole body computed tomography (CT) and positron emission tomography-CT (PET-CT) were all negative, which resulted in the misdiagnosis of Paget′s disease of bone initially. This highlights that malignancies involving bones presenting with isolated elevation of serum ALP levels might be misdiagnosed in asymptomatic individuals.

Paget's disease of the jaws: Histopathological features of a series of 31 cases / Enfermedad de Paget en los maxilares. Características histopatológicas de una serie de 31 casos

ABSTRACT The aim of the present study was to analyze the histopathological features of Paget's disease of the jaws observed in a series comprising 31 cases. The study comprised all cases of Paget's disease of the jaws filed in the archives of the Surgical Pathology Laboratory of the Oral Pathology Department, School of Dentistry, University of Buenos Aires, between 1960 and 2018. Their microscopic features were evaluated, and available clinical data and radiographic studies were analyzed. Paget's disease of the jaws accounted for 0.05% of retrieved oral-maxillofacial pathologies. Microscopically, all cases showed lamellar bone trabeculae with the characteristic mosaic pattern. Twenty cases (64%) showed osteoblastic-osteoclastic activity, and all showed areas of necrosis. Cemento-osseous trabeculae were observed in 15 cases (48%), and cementicles were observed in 13 (42%). Osteomyelitis was seen in 11 cases (35%), all of which showed cemento-osseous trabeculae with a mosaic structure, sclerosis and necrosis, and chronic inflammation with abscess formation. Mean age was 61 years (44-85 years); 19 cases were women. Localization was the maxilla in 13 cases (42%), and the disease involved other skeletal bones in five cases. To our knowledge, this is the largest series of Paget's disease of the jaws reported to date. Paget's disease is infrequent in the jaws and has distinct histopathological features that not only differ from those observed at other skeletal sites but also require differential diagnosis from other pathologies affecting the jaws exclusively.

RESUMEN El objetivo del presente trabajo fue analizar las características histopatológicas de la enfermedad de Paget en los maxilares en una serie de 31 casos. El estudio comprendió todos los casos de enfermedad de Paget de los maxilares provenientes del Laboratorio de Patología Quirúrgica de la Cátedra de Anatomía Patológica de la Facultad de Odontología de la Universidad de Buenos Aires, entre 1960 y 2018. Se evaluaron las características microscópicas y se analizaron los datos clínicos y estudios radiográficos disponibles. La enfermedad de Paget en los maxilares representó el 0,05% de las patologías buco-maxilofaciales. Microscópicamente, todos los casos mostraron trabéculas óseas laminares con el característico patrón en mosaico. Veinte casos (64%) mostraron actividad osteoblástica-clástica y todos los casos mostraron necrosis focal. En 15 casos (48%) las trabéculas presentaron aspecto cemento-óseo y en 13 casos (42%) se observaron cementículos. Once casos (35%) presentaron cuadros osteomielíticos y todos ellos mostraron trabéculas cemento-óseas con estructura en mosaico, esclerosis y necrosis, e infiltrado inflamatorio crónico con formación de abscesos. La media de edad fue 61 años (44- 85 años), y 19 fueron mujeres. Trece casos (42%) se localizaron en maxilar superior y 5 casos presentaron compromiso de otros huesos. A nuestro entender, esta es la serie más grande de enfermedad de Paget en los maxilares reportada hasta la fecha. La enfermedad de Paget es poco frecuente en los maxilares y presenta características histopatológicas que además de ser diferentes a las observadas en otros sitios del esqueleto plantean el diagnóstico diferencial con otras entidades que se presentan exclusivamente en los maxilares.

Abstract Paget's disease is a rare disorder of the nipple and/or the areola that is characterized by an erythematosquamous lesion and is often associated with in situ or invasive breast carcinoma. The authors present an atypical, exuberant case that had evolved over eight years, emphasizing the importance of early diagnosis.

Paget’s disease of the breast: a case series

Paget’s disease of the nipple is a rare disease with a rather bizarre presentation which makes the diagnosis easily missed. Three cases are presented here with different modes of presentation and histological findings. A biopsy provided the definitive diagnosis in the three patients and the treatments offered was based on the histological findings - modified radical mastectomy and simple mastectomy for invasive carcinoma and carcinoma in-situ respectively.

Enfermedad de Paget de hueso esporádica. Serie de casos y revisión de la literatura / Sporadic Paget's disease of the bone. Case series and literature review

RESUMEN La enfermedad de Paget ósea es una enfermedad metabólica del hueso de etiología no esclarecida, que se caracteriza por una fase de resorción aumentada seguida por una fase de osteoformación aberrante. Es frecuente en Europa, Norteamérica, Nueva Zelanda y Australia, pero infrecuente en Asia, Medio Oriente y África. En población colombiana hay reportes de casos. Generalmente cursa asintomática y se diagnostica incidentalmente por hallazgos radiográficos o fosfatasa alcalina elevada. El uso de bifosfonatos favorece el control del recambio óseo y permite prevenir complicaciones como las fracturas. Se presenta una serie de casos en Colombia y una revisión de la literatura.

A B S T R A C T Paget's disease of the bone is a metabolic bone disease of unknown origin, and is characterised by an increased phase of resorption, followed by an aberrant osteoformation phase. It is common in Europe, North America, New Zealand, and Australia, but infrequent in Asia, the Middle East, Africa, and in the Colombian population there are case reports. It is usually asymptomatic and is diagnosed incidentally by radiographic findings or an elevated alkaline phosphatase. The use of bisphosphonates favours the control of bone turnover and prevents complications such as fractures. A series of cases in Colombia is presented, along with a review of the literature.

Diagnostic value of high-frequency ultrasonography for Paget disease of breast / 中国介入影像与治疗学

Objective: To investigate the diagnostic value of high-frequency ultrasound for Paget disease of breast (PDB). Methods :High-frequency ultrasound data of 30 patients with pathology approved PDB were retrospectively analyzed, including 13 cases complicated with invasive ductal carcinoma (IDC). Ultrasonic appearances of PDB with or without IDC were compared. Results: Ultrasonic features of PDB included hypo-echogenicity in nipple, thicken areola skin, mammary nodules, calcification, dilated duct and enlarged axillary lymph nodes. Compared with PDB without IDC, PDB complicated with IDC showed more mammary nodules (P=0.001) and enlarged axillary lymph nodes (P=0.002). No significant difference of breast imaging reporting and data system (BI-RADS) classification, hypo-echogenicity in nipple, thicken areola skin, calcification nor dilated duct rate was found between groups (all P>0.05). Conclusion: PDB have certain ultrasonic characteristics. High-frequency ultrasound is helpful to diagnosis and assessment of PDB.

Caso Clínico: Enfermedad de Paget del Pezón / Clinical Case Report: Paget's Disease of the Nipple

INTRODUCCIÓN: La enfermedad de Paget del pezón es infrecuente y representa del 1 al 3 % de las neoplasias de mama. Está asociada con un carcinoma invasivo o in situ en el 82 al 94 % de los casos. Se presenta entre los 55 a 64 años de edad. CASO CLÍNICO: Se presenta el caso de una mujer de 58 años con zona de descamación de 1 cm2 indolora en pezón derecho y tumor de 4 cm2 en mama izquierda, ecografía y mamografía BI-RADS III. Biopsia incisional de pezón derecho que reportó enfermedad de Paget, con ampliación de márgenes. Se completó estudios de extensión con resonancia magnética que reportó lesión retro-areolar sospechosa en mama derecha y lesión nodular maligna en mama izquierda. EVOLUCIÓN: Se realizó cuadrantectomía central más neo-pezón en mama derecha, y en mama izquierda cuadrantectomía superoexterna con vaciamiento ganglionar axilar bilateral, el reporte de patología fue mama derecha negativa para malignidad, mama izquierda hiperplasia intraductal atípica con focos de carcinoma intraductal. Se administró 25 sesiones radioterapia, tras un año de seguimiento se mantiene sin recurrencia. CONCLUSIÓN: La enfermedad de Paget es poco frecuente, pero debe considerarse como diagnóstico diferencial en pacientes sobre los 55 años, su tratamiento estandarizado es quirúrgico, la adyuvancia con radioterapia aún es motivo de discusión. El autoexamen de mama, el acudir a controles periódicos a partir de los 40 años además de realizar una ecografía y mamografía nos lleva a diagnósticos tempranos con un elevado porcentaje de cirugías más conservadoras.(au)

BACKGROUND: Paget's disease of the nipple is uncommon and represents 1 to 3% of breast malignancies. It is associated with invasive or in situ carcinoma in 82 to 94% of cases. It occurs between 55 to 64 years old. CASE REPORT: We present the case of a 58 year old woman with a painless 1cm2 scaling skin lesion in the right nipple and a 4cm2 tumor in the left breast, ultrasound and mammograghy classified as BIRADS III. Incisional biopsy of the right nipple that reported Paget's¬ disease, with extension of surgical margins of resection. MRI extension studies were made; they reported suspicious retroaereolar lesion in the right breast and malignant nodular lesion in the left breast. EVOLUTION: We performed central quadrantectomy with nipple reconstruction in the right breast, and superoexternal quadrantectomy in the left breast, with bilateral axillary lymph node dissection, the pathology report was negative for malignancy in the right breast, in the left breast atypical intraductal hiperplasia with foci of intraductal carcinoma. The patient received 25 radiotherapy sessions. After one year of follow-up there is no recurrence. CONCLUSIONS: Paget's disease is rare, but should be considered as a differential diagnosis in patients over 55 years, its standardized treatment is surgery, adjuvant treatment with radiotherapy is still a matter of discussion. Breast self-exam, regular checkups in people over 40 years old, ultrasound and mammogram lead to early diagnosis with a higher percentage of conservative surgeries.(au)
