Diagnóstico de precisão das lesões mamárias / Accurate diagnosis of breast lesions

PONTOS-CHAVE As lesões mamárias compreendem uma ampla variedade de diagnósticos que apresentam comportamentos diversos. As lesões mamárias podem ser classificadas como lesões benignas, de potencial de malignidade indeterminado (B3), carcinoma in situ e carcinoma invasor. Na era da medicina personalizada, individualizar e obter um diagnóstico preciso faz grande diferença no desfecho final da paciente, principalmente no caso do câncer de mama. Exames de imagem direcionados e de qualidade, métodos de biópsia adequadamente selecionados e análises de anatomopatologia convencional, imuno-histoquímica e até molecular são determinantes no diagnóstico e no manejo das pacientes.

Underestimation Rate in the Percutaneous Diagnosis of Radial Scar/Complex Sclerosing Lesion of the Breast: Systematic Review / Taxa de subestimação no diagnóstico percutâneo de cicatriz radiada/lesão esclerosante complexa da mama: Revisão sistemática

Abstract Objective To evaluate the underestimation rate in breast surgical biopsy after the diagnosis of radial scar/complex sclerosing lesion through percutaneous biopsy. Data Sources A systematic review was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The PubMed, SciELO, Cochrane, and Embase databases were consulted, with searches conducted through November 2020, using specific keywords (radial scar OR complex sclerosing lesion, breast cancer, anatomopathological percutaneous biopsy AND/OR surgical biopsy). Data collection Study selection was conducted by two researchers experienced in preparing systematic reviews. The eight selected articles were fully read, and a comparative analysis was performed. Study selection A total of 584 studies was extracted, 8 of which were selected. One of them included women who had undergone a percutaneous biopsy with a histological diagnosis of radial scar/complex sclerosing lesion and subsequently underwent surgical excision; the results were used to assess the underestimation rate of atypical and malignant lesions. Data synthesis The overall underestimation rate in the 8 studies ranged from 1.3 to 40% and the invasive lesion underestimation rate varied from 0 to 10.5%. Conclusion The histopathological diagnosis of a radial scar/complex sclerosing lesion on the breast is not definitive, and it may underestimate atypical andmalignant lesions, which require a different treatment, making surgical excision an important step in diagnostic evaluation.

Resumo Objetivo Avaliar o grau de discordância entre biópsia percutânea e cirúrgica da mama em pacientes com diagnóstico de cicatriz radiada/lesão esclerosante complexa (CR/LEC) por meio de uma revisão sistemática. Fontes dos dados Foi realizada uma revisão sistemática segundo as recomendações do Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA, na sigla em inglês). As bases de dados primárias consultadas foram PubMed, SciELO, Cochrane e Embase, combuscas conduzidas até novembro de 2020, utilizando palavras chaves específicas (cicatriz radiada OU lesão esclerosante complexa, câncer de mama, anatomopatológico de biópsia percutânea E/OU biópsia cirúrgica). Seleção dos estudos A busca dos artigos resultou em um total de 584 estudos, sendo 8 selecionados, os quais incluíam mulheres submetidas a biópsia com diagnóstico histológico de CR/LEC e posteriormente submetidas a exérese cirúrgica para avaliar como desfecho o grau de subestimação de lesões atípicas e malignas. Coleta de dados A seleção dos estudos foi conduzida por dois pesquisadores, com experiência na elaboração de revisão sistemática. Os oito artigos selecionados foram lidos na íntegra e submetidos a uma análise comparativa. Síntese dos dados Cicatrizes radiadas/lesões esclerosante complexas foram associadas com lesões atípicas e malignas após a exérese cirúrgica. O grau de subestimação geral foi calculado pela porcentagem de lesões atípicas e malignas no anatomopatológico após a exérese cirúrgica dentre o total de CR/LEC diagnosticadas, enquanto o grau de subestimação de lesões invasoras foi calculado considerando-se apenas os carcinomas invasivos. O grau de subestimação geral dos estudos selecionados variou de 1,3 a 40%, e o de lesões invasoras de 0 a 10,5%. Conclusão O diagnóstico histopatológico de CR/LEC na mama não é definitivo, podendo subestimar lesões atípicas e malignas, cujo tratamento é distinto, tornando a exérese cirúrgica etapa fundamental na investigação diagnóstica.

Correlation of nipple eczema in pregnancy with atopic dermatitis in Northern India: a study of 100 cases

Abstract Background Nipple eczema is a less common presentation of atopic dermatitis. No studies in the literature have correlated nipple eczema in pregnancy as a manifestation of atopic dermatitis. Objective To evaluate whether nipple eczema presenting in pregnancy is a manifestation of atopic dermatitis. Methods This was a prospective observational study including 100 women who presented with nipple eczema for the first time during pregnancy. The exclusion criteria were any patient with previous history of nipple eczema, those already on oral or topical treatment for atopic dermatitis or nipple eczema, and other disorders mimicking eczema. Patients were divided into two groups ‒ nipple eczema with atopic dermatitis and without atopic dermatitis. Demographic data, clinical features, total leukocyte count, differential leukocyte count, absolute eosinophil counts, and serum IgE levels were compared between the two groups to detect association between nipple eczema in pregnancy and atopic dermatitis. Results Out of 100 patients, 39 were diagnosed with atopic dermatitis, whereas 61 were ruled out to have any features suggestive of atopic dermatitis. There were no statistically significant differences in mean age, mean duration of symptoms, and serum IgE levels. In patients with atopic dermatitis, bilateral symptoms were noted more commonly than in patients without the disease, but this was statistically insignificant. Study limitations Lack of long term follow-up and no large studies in literature to compare results. Conclusion Nipple eczema in pregnancy follows a similar pattern as in other age groups. The clinical profile of patients is similar in cases with and without atopic dermatitis.

Ectasia ductal mamaria, una entidad poco frecuente en la edad pediátrica: A propósito de un caso / Duct ectasia, an infrequent condition in childhood: A case report

La secreción sanguínea a través del pezón (telorragia) es un síntoma muy poco frecuente y que genera gran alarma en pediatría por su relación con el carcinoma en la edad adulta. La entidad más frecuente asociada en edades tempranas, de naturaleza benigna y autolimitada, es la ectasia ductal mamaria. Se caracteriza por la dilatación del conducto mamario, fibrosis e inflamación periductal. La etiología es desconocida y multifactorial. Son pocos casos los descritos en la literatura científica. Se presenta a un lactante de 5 meses con telerragia por ectasia ductal mamaria, cuya resolución fue espontánea a las 4 semanas. Nuestro objetivo es facilitar el rápido reconocimiento por parte de los médicos, dar a conocer esta patología tan poco frecuente y, así, evitar estudios y tratamientos agresivos e invasivos innecesarios.

Bloody discharge from the nipple (thelorrhagia) is a rare symptom in childhood and is a cause of great concern due to the association with carcinoma in adults. The most common cause in children is mammary duct ectasia, which is a benign and self-limiting condition. It is characterized by dilatation of the mammary ducts, fibrosis and periductal inflammation. The etiology has not been identified and is multifactorial. Up to date, only isolated case reports have been published. Therefore, we present a review of the literature and we report a case of a fivemonth- old male infant that resolves spontaneously. We aimed to improve physicians’ diagnosis accuracy, the knowledge of this condition and to avoid aggressive studies and treatments.

Cat scratch disease presenting as axillary lymphadenopathy and a palpable benign mammary nodule mimicking a carcinoma

Abstract We present a case involving a 74-year-old woman with cat scratch disease characterized by an enlarged and hard axillary lymph node as well as a palpable breast nodule mimicking a carcinoma. The lymph node and the breast nodule were excised. The pathologic examinations revealed granulomatous lymphadenitis with gram-negative bacilli and an intraductal papilloma. Antibiotic therapy (azithromycin) was prescribed and the patient's clinical evolution was excellent.

Mastopatía diabética: a propósito de un caso clínico / Diabetic mastopathy: a clinical case

La mastopatía diabética es una lesión fibroinflamatoria de la mama muy infrecuente, que característicamente se presenta en mujeres premenopáusicas y está fuertemente asociada a diabetes mellitus tipo I. La patogénesis es desconocida, sin embargo, histopatológicamente se ha observado una reacción en el tejido conectivo similar al de algunas enfermedades autoinmunes. La clínica y exámenes complementarios pueden ser sugerentes de neoplasia, por lo que se requiere estudio histopatológico para establecer el diagnóstico definitivo.

Diabetic mastopathy is a very infrequent fibro-inflammatory lesion generally found in pre-menopausal women and is strongly associated with type 1 diabetes mellitus. Its pathogenesis is unknown; however its histopathology shows a connective tissue reaction similar to that of some auto-immune diseases. Its clinical presentation and complementary tests may suggest neoplasm, thus definitive diagnosis requires a histopathological study.

Calcificaciones mamarias: descripción y clasificación según la 5ª edición BI-RADS / Breast calcifications: description and classification according to BI-RADS 5th edition

Abstract. Breast calcifications are frequent findings in mammography. Most of them have a benign origin, such as in the case of the response to inflammatory disease of the ducts or coarse calcifications in benign nodules. Many of these calcifications show a characteristic benign appearance, and they do not need to be magnified or monitored. However, other calcifications can show a grouped pattern, have a suspicious appearance, and transform into an in situ ductal carcinoma or a high risk breast lesion. It is important to know the morphological and distribution patterns of these calcifications in order to make right decisions for each case. In the 5th edition of the BI-RADS atlas, 2013, categories and levels of suspicion for some patterns were modified. The objective of this article is to update descriptors and categories of BI-RADS micro-calcifications, pointing out their most important features and malignancy risk linked to each descriptor.

Resumen. Las calcificaciones mamarias son un hallazgo frecuente en mamografía. La mayoría de ellas tienen un origen benigno, como puede ser la respuesta a patología inflamatoria de los conductos o calcificaciones gruesas en nódulos benignos. Muchas de estas calcificaciones presentan un aspecto benigno característico y no requieren ser magnificadas o controladas. Otras calcificaciones sin embargo pueden presentarse agrupadas, tener un aspecto sospechoso y originarse en un carcinoma ductal in situ o una lesión de alto riesgo. Es relevante conocer los patrones morfológicos y de distribución de estas calcificaciones a fin de tomar la conducta adecuada para cada caso. En la 5.ª edición del atlas BI-RADS, 2013, las categorías y grados de sospecha de algunos patrones fueron modificados. El objetivo del presente artículo es realizar una actualización de los descriptores y las categorías BI-RADS de las microcalcificaciones, señalando sus características más importantes y el riesgo de malignidad asociado a cada descriptor.

Mastopatía diabética: una entidad infrecuente a diferenciar / Diabetic mastopathy: an uncommon entity to differentiate

Antecedentes. La diabetes mellitus produce microvasculitis y alteración histoarquitectural de la mama. Se encuentra en el 1% de la mastopatía benigna. Sin embargo, la distorsión del parénquima produce sintomatología inflamatoria clínicamente similar a las mastopatías inflamatorias infecciosas. Su diagnóstico imagenológico es, a su vez, de gran dificultad interpretativa. Estos parámetros inespecíficos desembocan en tratamientos que no logran eficacia en la enfermedad, más aún si se ignora el contexto de la enfermedad de origen, la cual es sistémica. Objetivos. Destacar la importancia del diagnóstico diferencial de esta infrecuente entidad patológica. Material y Métodos. Se revisaron historias clínicas de un servicio de mastología por el término de seis meses a efectos de recabar información estadística. Población. Se estudiaron dos pacientes en un universo de más de cien historias clínicas abordadas. Resultados. Histológicamente, estas pacientes presentaron rasgos microscópicos que consisten en una lobulitis linfocitaria que afecta al epitelio y gran vasculitis edematosa. El diagnóstico histológico es crucial para llegar al tratamiento. Discusión y conclusiones. La mastopatía de las pacientes diabéticas insulinodependientes es la manifestación crónica de eventos sistémicos, producida en un porcentaje muy bajo de pacientes con la enfermedad. La correcta interpretación clínica y mamográfica, además de la sospecha semiológica, desembocan en el adecuado tratamiento de esta enfermedad inserta en un contexto sistémico.

Background. Diabetes mellitus occurs histoarquitectural microvasculitis and alteration of the breast. It is found in 1% of benign breast disease. However, distortion occurs parenchymal inflammatory symptoms clinically similar to infectious inflammatory breast disease. Its diagnostic imaging is in turn highly interpretive difficulty. These nonspecific parameters lead to effective treatments that fail in the disease, especially if the context of disease origin is unknown, which is systemic. Objectives. To highlight the importance of the differential diagnosis of this rare disease entity. Material and methods. Clinical histories mastology service for a period of six months for the purpose of collecting statistical data were reviewed. Population. Two patients were studied in a universe of more than one hundred medical records addressed. Results. Histologically, these patients had microscopic features consisting lobulitis lymphocytic affecting large edematous epithelium and vasculitis. Histological diagnosis is crucial to get the treatment. Discussion and conclusions. Diabetic mastopathy in insulin dependent patients is chronic manifestation of systemic events produced in a very low percentage of patients with the disease. The correct clinical and mammographic interpretation, in addition to lead to suspicion semiológica proper treatment of this disease, inserted in a systemic context.

Enfermedad de Rosai-Dorfman mamario / Mammary Rosai Dorfman disease

Background: Rosai Dorfman disease is uncommon and consists in a benign fibrous and hematopoietic tissue proliferation, usually located in the head or neck. It is self-limited and the treatment is the surgical excision of the lesion. Case Report: We report a 69 years old woman consulting for a palpable right breast nodule with a mammography and mammary ultrasound informed as BIRADS 4 and 5, respectively. A core biopsy was informed as a mammary Rosai Dorfman disease. Two years later, due to a lesion growth, the patient was subjected to a partial mastectomy. The pathological study of the surgical piece confirmed the diagnosis of the core biopsy. This disease may resemble a malignant disease and the clue for its diagnosis is the pathological study.

Introducción: La enfermedad de Rosai Dorfman es una entidad infrecuente, que consiste en la proliferación benigna del tejido fibroso y hematopoyético ubicado generalmente en cabeza y cuello. Se trata de una enfermedad benigna, autolimitada, cuyo tratamiento generalmente se limita a la resección quirúrgica, con elevada tasa de recidiva. Objetivo: Exposición de un caso de Enfermedad de Rosai Dorfman mamario, inicial-mente sugerente de patología maligna. caso clínico: Mujer 69 años derivada de atención primaria por nódulo palpable en mama derecha, mamografía y ecografía mamaria BIRADS 4 y 5, respectivamente. Biopsia Core informa Enfermedad de Rosai Dorfman mamaria. A los dos años de diagnóstico se objetiva lesión de mayor tamaño. Se realizó mastectomía parcial con biopsia de pieza quirúrgica compatible con diagnóstico de Biopsia Core previa. Discusión: La similitud clínica de esta enfermedad con patologías malignas mamarias, asociado a su baja prevalencia, dificultan la pesquisa de casos como el expuesto. En los estudios de imágenes raramente se sospecha. La clave del diagnóstico son los hallazgos histológicos en el que característicamente se observa emperipolesis con tinciones inmunohistoquímicas positivas para S 100 y negativo para CD 1. Dado que es una enfermedad benigna y autolimitada su tratamiento generalmente se limita a la resección quirúrgica. Este permite extirpar el tumor en estudio, realizar el diagnóstico, y aliviar la sintomatología producida por el efecto masa de la lesión. A pesar de lo anterior la recidiva es alta, por lo que el seguimiento debe ser a largo plazo.

Diagnostic accuracy of high frequency ultrasound and mammography in breast lump

The study was conducted to evaluate the diagnostic accuracy of high frequency ultrasound and mammography in common breast lumps. Observational study. This study was carried at Radiology Department, LUMHS and NIMRA Jamshoro/Hyderabad and Isra University Hospital, Hyderabad from June 2008 to June 2012. A sample of 520 female of age 20 - 80 years presenting with breast lumps after initial examination were evaluated for further benignity or malignancy using ultrasonography and mammography. The findings were then compared with both diagnostic modalities. Data were entered and analyzed by using SPSS 21.0. Continuous and categorical variables were analyzed by student t test and chi square test. A p value =/< 0.05 was considered statistically significant. Mean +/- SD of age was noted as 45.69 +/- 10.77 years. Most of the patients were married [76.9%] and belonged to middle age group [51.5%]. There were insignificant associations observed when we compared the underlying diagnosis with the diagnostic techniques used [p=0.075]. On the other hand, the diagnosis in young age group was significantly made by using ultrasonography and in older group mammography was the diagnostic modality of choice [p = 0.020]. Non-invasive test such as ultrasonography should be the preferred technique in young patients who present clinically with abreast lump

Hiperplasia pseudoangiomatosa nodular gigante de la mama / Pseudoangiomatous stromal hyperplasia (pash) of the breast

La hiperplasia pseudoangiomatosa (PASH) es una lesión proliferativa benigna de la mama, poco frecuente, caracterizada por la existencia de lagos pseudovasculares embebidos en una gran proliferación del estroma mamario. Probablemente, el desarrollo de la PASH tenga una influencia hormonal, por lo que típicamente se diagnostica en mujeres en edad fértil. La PASH es un hallazgo histopatológico casual en las piezas quirúrgicas y biopsias mamarias realizadas por otra patología. La presentación clínica en forma de masa palpable es poco frecuente. El principal diagnóstico diferencial debe realizarse con el angiosarcoma de bajo grado. El tratamiento de la PASH nodular es una correcta exéresis quirúrgica asegurando borde sano amplio. El pronóstico es excelente, con un mínimo riesgo de recidiva si se realiza una adecuada cirugía. Se presenta el caso de una mujer de 37 años que acude a consulta por un nódulo mamario de crecimiento rápido.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast is a rare benign proliferative mesenchymal lesion characterized by the presence of open slit like spaces embedded in a hyalinized fibrous stroma. The development of PASH is probably subject to hormonal influence so it typically affects women in the reproductive age group. Pseudoangiomatous stromal hyperplasia is frequently an incidental histologic finding in breast surgeries or biopsies performed for other injuries. In rare cases, it presents as a localized breast mass. The most important differential diagnosis is low-grade angiosarcoma. Tumorous PASH is treated by local surgical excision with clear margins. The prognosis is excellent, with minimal risk of recurrence after adequate surgery. The presented case was a 37-years-old woman who was admitted with a rapidly growing breast tumor.

Hamartoma e hiperplasia estromal pseudoangiomatosa de la mama, diagnósticos diferenciales infrecuentes de cáncer de mama / Hamartoma and nodular pseudoangiomatous stromal hyperplasia: differential diagnosis

Introducción: Los hamartomas y la hiperplasia estromal pseudoangiomatosa nodular (PASH) son entidades infrecuentes en la patología tumoral mamaria, sin embargo, pueden simular al cáncer de mama. La única herramienta certera preoperatoria es la biopsia. El tratamiento quirúrgico es curativo con bajo índice de recurrencia. Objetivo: El objetivo de este trabajo es exponer un caso de hamartoma mamario con PASH asociado cuya presentación inicial fue sugerente de probable patología maligna. Caso Clínico: Mujer de 44 años, ingresa a controles por probable patología mamaria maligna, la mamografía fue informada como BIRADS 0, la ecografía mamaria como BIRADS US: 5, la biopsia CORE informó PASH. Se realizó mastectomía parcial objetivando en la biopsia diferida un hamartoma mamario con extensa hiperplasia estromal pseudoangiomatosa. Discusión: Los hamartomas y la PASH son patologías sin presentación clínica específica, los hallazgos radiológicos del hamartoma pueden ser patognomónicos, no así en la PASH; en el caso expuesto el estudio anatomopatológico demostró una asociación de estas patologías, la cual se describe desde un 16 por ciento a un 71 por ciento de los casos de hamartoma mamario. El análisis de toda la pieza quirúrgica es fundamental para establecer un diagnóstico definitivo.

Introduction: Hamartoma and nodular pseudoangiomatous stromal hyperplasia (PASH) are inusual breast tumor entities, however, can simulate breast cancer. The only accurate tool is preoperative biopsy. Surgical treatment is curative with low recurrence rate. Objective: To present a case of mammary hamartoma associated with PASH whose initial presentation was suggestive of probable malignancy. Case Report: Woman, 44 years old, admitted to controls because of probable malignant breast disease, mammography was reported as BIRADS 0, breast ultrasound as BIRADS U.S: 5, CORE biopsy reported PASH. Partial mastectomy was performed. On delayed biopsy mammary hamartoma with extensive stromal hyperplasia pseudoangiomatosa was diagnosed. Discussion: PASH and hamartomas are diseases with no specific clinical presentation, radiological findings may be pathognomonic of hamartoma, while not in PASH. In the reported case the pathological study showed an association of these conditions, described in a 16% to 71% breast hamartoma cases. The analysis of the entire surgical specimen is essential for a definitive diagnosis.

Mondor's disease in puerperium: case report / Doença de Mondor no puerpério: caso clínico

Mondor's disease is a rare entity characterized by sclerosing thrombophlebitis classically involving one or more of the subcutaneous veins of the breast and anterior chest wall. It is usually a self-limited, benign condition, despite of rare cases of association to cancer. We present the case of a 32 year-old female, breast-feeding, who went to emergency due to left mastalgia for the past week. She was taking antibiotics and non-steroidal anti-inflammatory drugs, previously prescribed for suspicious of mastitis, for three days, with no clinical improvement. Physical examination showed an enlarged left breast, an axillary lump and a painful cord-like structure in the upper outer quadrant of the same breast. Ultrasound scan showed a markedly dilated superficial vein in the upper outer quadrant of left breast. The patient was given a ventropic therapy and was kept in anti-inflammatory, with progressive pain improvement. Ultrasound control was performed after four weeks, showing reperfusion.

A doença de Mondor é entidade rara caracterizada por tromboflebite esclerosante envolvendo classicamente uma ou mais das veias subcutâneas da mama e da parede torácica anterior. Trata-se de condição benigna normalmente auto-limitada, apesar de raros casos de associação ao câncer. Descreve-se o caso de uma mulher lactante de 32 anos de idade, que procurou serviço de emergência devido a mastalgia do lado direito na última semana. A paciente estava tomando antibióticos, mas não medicamentos esteroides anti-inflamatórios, previamente prescritos devido a suspeita de mastite, nos últimos três dias, sem melhora clínica. O exame físico mostrou o seio esquerdo aumentado, um nódulo axilar e uma estrutura dolorosa em formato de corda no quadrante superior externo da mesma mama. A ultrassonografia revelou uma veia superficial acentuadamente dilatada no quadrante superior externo da mama esquerda. A paciente recebeu terapia venotrópica and manteve o tratamento com anti-inflamatórios, com melhora progressiva da dor. Controle ultrassonográfico foi realizado após quatro semana, mostrando reperfusão.

Thrombophlebitis of the lateral chest wall (Mondor's disease).

Mondor's disease is a rare condition, which involves the thrombophlebitis of the superficial veins of the breast and anterior chest wall. A 37-year-old woman presented with sudden onset of local pain and edema on her right chest wall, accompanied by a longitudinal retraction of the skin during arm abduction in the area. Clinical, histological and ultrasonographic findings confirmed Mondor's disease and the treatment was symptomatic, using pain relievers and warm compresses. The symptomatology remitted within 2 weeks of therapy. Mondor's disease is a rare condition where ultrasound complements the clinical evaluation and allows the characterization of certain abnormalities, which correlated with functional biochemical data and other procedures may substitute the need of biopsy.

Low tension breast hydatid cyst-A case report

Features of low tension in breast hydatid cyst and symptoms secondary to cyst dying and disintegration are unique and not yet reported in the literature. An young woman of 30 years complained about pain and vague swelling in the right breast during follow-up with albendazole therapy following second laparotomy for post-surgical residual cavity of hydatid cyst in the left lobe of the liver. Breast ultrasound was diagnostic. Segmental breast excision revealed a large dead hydatid cyst. Postoperative course was uneventful. Breast hydatid cyst may become symptomatic and hypotensive after start of albendazole therapy

Pioderma gangrenoso en mamoplastía de reducción con pedículo inferior / Pyoderma gangrenosum secondary to reduction mammoplasty

Background: Pyoderma gangrenosum (PG) is an uncommon inflammatory and ulcerative disorder of the skin. It may be associated with immune deficiencies. It is usually located in the extremities and its appearance after reduction mammoplasty is exceptional. We report three patients with the disease. A 54 years old female subjected to a bilateral reduction mammoplasty with an inferior pedicle. She developed a pyoderma gangrenosum and was treated with systemic steroids and local application of Dapsone with remission of lesions and healing after one month of evolution. A 23 years old women subjected to the same surgical procedure, which developed a wound dehiscence with ulcerative lesions, was treated with steroids and Azathioprine, reducing the local inflammation but leaving a severe esthetic sequel. A 21 years old woman subjected to the same surgical procedure, develop bilateral wound dehiscence and ulcerative lesions, she was treated with steroids and antimicrobials achieving a secondary healing...

Introducción: El Pioderma Gangrenoso es una enfermedad poco frecuente, de difícil diagnóstico y manejo. Puede estar asociado a otras enfermedades, en donde la alteración de la respuesta inmune es común. Su presentación por lo general corresponde a lesiones ulceradas de la piel ubicadas con frecuencia en las extremidades, siendo su presentación en las mamas excepcional; y mucho más rara su relación post mamoplastía de reducción. Métodos: Se realizó una revisión de pacientes sometidas a mamoplastía de reducción con pedículo inferior, asociadas al desarrollo de pioderma gangrenoso post-quirúrgico, durante un período comprendido entre los años 2000 y 2011. Resultados: Se recolectaron 3 pacientes, se describen sus casos clínicos con respecto a esta ubicación, analizando su presentación, evolución y manejo de la enfermedad. Discusión: La presentación del pioderma gangrenoso post-quirúrgico en relación a la mamoplastía de reducción comparte ciertas similitudes, las cuales deben orientar al diagnóstico precoz y de esta forma evitar manejos erróneos que pueden ser deletéreos, secuelantes e incluso potencialmente mortales...

Gangrena gaseosa de la mama / Gas gangrene of the breast

La gangrena gaseosa de la mama es una enfermedad rara y potencialmente mortal descrita como consecuencia de un traumatismo, por complicaciones infecciosas de la cirugía o por una trombosis venosa. También se ha relacionado ocasionalmente con otras causas tales como la diabetes mellitus, el envenenamiento con monóxido de carbono o la cirugía plástica. Presentamos un caso de gangrena gaseosa de mama en una mujer diabética de 74 años. Esta rara infección representa una emergencia médico-quirúrgica(AU)

Gas gangrene of the breast is a rare and potentially lethal disease following trauma, as a result of infectious complications from surgery or venous thrombosis. Other rare etiologies, such as diabetes mellitus, carbon monoxide poisoning, and plastic surgery, have also been reported as related to this illness. A case of gas gangrene of the breast found in a 74-year-old diabetic woman was presented in this paper. This rare infection is a medical and surgical emergency situation(AU)

Pleomorphic MPNST of Breast.

Malignant peripheral nerve sheath tumors (MPNST) are a rare type of soft tissue sarcomas accounting for 5-10% of all sarcoma cases.They are a tumor of adult age group occuring in patients 20-50 years of age.Though these tumors due to their schwann cell origin may occur anywhere near a nerve trunk, breast is a rare site of its occurence.They are rare breast tumors which in association with type 1 neurofibromatosis syndrome .We report a case of pleomorphic MPNST occuring in a 32 years old female patient without any evidence of Neurofibromatosis 1 syndrome.

Diagnostic usefulness of Tru-Cut biopsy in the diagnosis of breast lesions

To evaluate the usefulness of Tru-Cut biopsy [TCB] in the diagnosis of breast lesions. An observational non-interventional cross-sectional review was performed of all TCB reports of a mass or lesion observed in patients admitted between January 2008 and December 2010, at King Khalid University Hospital, Riyadh, Saudi Arabia. A total of 275 trucut biopsies were performed during the study period. Histopathology showed 92 [33.5%] malignant lesions, 177 [64.3%] benign lesions and 6 [2.2%] suboptimal or suspicious lesions. Repeat trucut biopsies were done in 29 [16.4%] of the benign cases, 12 [13%] of the malignant cases, and for 6 inconclusive specimens which showed 4 of the 29 benign cases to be malignant lesions, and 5 of the 6 inconclusive cases were also malignant lesions. All 12 malignant cases that had repeat trucut biopsy had a confirmed diagnosis of malignancy. Trucut biospy had a sensitivity of 95.1%, specificity of 100%, positive predictive value of 100%, negative predictive value of 97.2%, and an overall diagnostic accuracy of 98.2%. Trucut biopsy is an accurate alternative to fine needle aspiration cytology in the diagnosis of breast lesions with a high diagnostic accuracy of 98.2%
