ABSTRACT

Metaplastic breast carcinoma is a rare subtype of invasive breast carcinoma. Metaplastic carcinoma with osseous differentiation is exceptionally uncommon. Because of the heterogenous microscopy of the lesion, various clinical and radiological features are observed, leading to diagnostic difficulty. Herein, we present a case of a 43-year-old female with a recurrent breast lump, who was clinically diagnosed as a phyllodes tumor. However, histopathological examination revealed metaplastic carcinoma with extensive osseous differentiation.

ABSTRACT

Phyllodes tumors account for less than 1% of tumors of the mammary gland, have both epithelial and stromal components and are classified as benign, borderline and malignant. The malignant tumors are highly heterogeneous: they can differentiate to liposarcomas, fibrosarcomas, rhabdomyosarcomas, chondrosarcomas or osteosarcomas. The differentiation to osteosarcoma is extremely rare, constitutes 1.3% of cases and is very aggressive. The standard treatment of these tumors is surgical. The role of radiotherapy and chemotherapy is not clear. However, in patients in whom wide surgical margins are not achieved, adjuvant radiotherapy can be of help. We report a 63 years old female with a right breast osteosarcoma with an osteoclastic component, originating in a phyllodes tumor. The tumor was excised surgically and afterwards she was treated with 10 sessions of 50 Gy of radiotherapy in 25 fractions. She has remained free of disease for the last 10 months.

ABSTRACT

Los tumores Phyllodes agrupan un conjunto de patologías caracterizadas por presentar una arquitectura histológica estromal y epitelial; dividiéndose en benignos, borderline o malignos, en función de múltiples características. Se desarrollan más frecuentemente en pacientes entre los 35-55 años de edad, representando el 0.3%-1% de los tumores primarios de la mama. Clínicamente se caracterizan por la aparición de una masa indolora, firme, dura, multilobulada y de crecimiento rápido que puede llegar a alcanzar un gran tamaño, denominándose gigantes cuando superan los 10 cm de longitud. El diagnóstico de los tumores Phyllodes, se basa en el estudio anatomopatológico mediante biopsia radioguiada y las pruebas de imagen mamarias. La cirugía conservadora o radical, con márgenes de resección quirúrgica libres de enfermedad mayores de 1 cm, y la radioterapia adyuvante sobre el lecho tumoral, son el tratamiento de elección de este tipo de tumores. El tamaño de la masa, el tipo histológico y la afectación tumoral de los bordes quirúrgicos son los principales factores de riesgo de recurrencia, que puede alcanzar un 40%, siendo casi siempre a nivel local. Por otro lado, la probabilidad de desarrollar metástasis a distancia presenta una mayor variabilidad, siendo más frecuente a nivel pulmonar y óseo. A continuación, presentamos el caso de una paciente diagnósticada de un tumor Phyllodes maligno gigante de mama derecha (mayor de 20 cm) que, tras tratamiento mediante cirugía radical y radioterapia adyuvante, desarrolló múltiples metástasis a distancia, recibiendo actualmente cuidados paliativos, a pesar de los esfuerzos terapéuticos multidisciplinares realizados.


Those Phyllodes tumors grouped a set of pathologies characterized by presenting an architecture histological stromal and epithelial; divided into benign, borderline or malignant, based on multiple characteristics. Occur most frequently in patients between 35-55 years of age, representing 0.3% - 1% of primary tumors of the breast. Clinically is characterized by the appearance of a mass painless, firm, hard, multilobulated and of growth fast that can get to reach a great size, calling is giant when exceed the 10 cm of length. Phyllodes tumors diagnosis, based on the study pathological radioguided biopsy and breast imaging tests. It surgery conservative or radical, with margins of resection surgical free of disease greater of 1 cm, and the radiation therapy adjuvant on the bedding tumor, are the treatment of choice of this type of tumors. He size of the mass, the type histologically and it involvement tumor of them edges surgical are the main factors of risk of recurrence, that can reach a 40%, being almost always to level local. On the other hand, the probability of developing metastasis to distance presents a greater variability, being more frequent to level lung and bone. Then, present the case of a patient diagnosed of a tumor Phyllodes malignant giant of mama right (greater of 20 cm) that, after treatment by surgery radical and radiotherapy adjuvant, developed multiple metastasis to distance, receiving currently care palliative, despite those efforts therapeutic multidisciplinary made.

ABSTRACT

Introduction: Breast Phyllodes tumors are rare breast tumors present in less than 1% of new cases of breast cancer, usually occurring among middle-aged women (40-50 yrs). Objective: This study shows diagnostic experience, surgical management and follows up of patients with this disease during a period of ten years in a oncology referral center. Methods: Retrospectively, breast cancer registries at the institution were reviewed, identifying 77 patients with Phyllodes tumors between 2002 and 2012, who had been operated on at the Instituto de Cancerología - Clínica Las Américas, in Medellín (Colombia). Clinical and histopathological data belonging to these cases was captured and analyzed and descriptive statistics were used. Results: The follow up median was 22.5 months (IQR: 10.5-60.0), average age was 47.2 yrs (SD: 12.4), mean tumor size was 3.6 cm (SD: 4.6), 88.3% of the patients (68 cases) presented negative margins and none of them received adjuvant chemotherapy. Of the patients with Phyllodes tumors; 33.8% had benign, 31.2% had borderline and 35.0% had malignant tumor. Disease-free survival was 85.8% and overall survival was 94.5%. Discussion: Reported data in this article is in accordance with what has been reported in worldwide literature. In our cohort even the high mean size of the tumors, the risk of local relapse and metastatic disease is low than previously reported in literature. Trials with longer follow up and molecular trials in Phyllodes tumors are necessary to understand the behavior of these tumors in Hispanics population.


Introducción: Los tumores phyllodes mamarios son Tumores infrecuentes en la mama presentes en menos del 1% de los casos nuevos de cáncer mamario, por lo general ocurre en mujeres de mediana edad (40-50 años) Objetivo: Este estudio muestra la experiencia de diagnóstico, tratamiento quirúrgico y seguimiento de los pacientes con esta variedad de tumor durante un período de diez años en un centro de referencia oncológico. Métodos: Retrospectivamente, los registros de cáncer de mama en la institución fueron revisados, se identificaron 77 pacientes con tumores phyllodes entre 2002 y 2012, que habían sido operados en el Instituto de Cancerología - Clínica Las Américas, en Medellín (Colombia). Los datos clínicos e histopatológicos pertenecientes a estos casos fueron recolectados y analizados utilizando técnicas de estadística descriptivas. Resultados: La mediana de seguimiento fue de 22.5 meses (RIC: 10.5-60.0), la Media de edad fue de 47.2 años (DE: 12.4), tamaño medio del tumor fue de 3.6 cm (DE: 4.6), 88.3% de los pacientes (68 casos) presentaron márgenes negativos y ninguno de ellos recibieron quimioterapia adyuvante. De los pacientes con tumores phyllodes; 33.8% fueron benignos, 31.2% Borderline y 35.0% phyllodes maligno. Supervivencia libre de enfermedad fue 85.8% y la supervivencia global fue de 94.5%. Discusión: Los datos reportados en este artículo están acordes con lo que se ha reportado en la literatura mundial. En nuestra cohorte, a pesar de que el tamaño promedio de los tumores fue mayor, el riesgo de recidiva local y las tasas de enfermedad metastásica es menor que el reportado previamente en la literatura. Los ensayos con seguimiento más prolongado, y los ensayos moleculares en tumores phyllodes son necesarios para comprender de una manera mas precisa el comportamiento de estos tumores en la población hispana.

ABSTRACT

Background: Phyllodes tumors are group of biphasic fibroepithelial tumors of the breast of varying malignant potential, ranging from benign tumors to fully malignant sarcomas. According to the Egyptian National Cancer Institute, female malignant cases showed appreciable increase in the recent time period for breast cancer with the malignant phyllodes tumors representing 0.41% of cases in the year 2003-2004. Aims: This is an immunohistochemical study to compare CD10 expression in benign, borderline, and malignant phyllodes tumors, in order to highlight its diagnostic and prognostic values. Materials and Methods: This study conducted 34 Egyptian female cases of phyllodes tumors of different grades to be studied histologically and immunohistochemically using antibodies against CD10. Statistical Analysis: The Chi-square test was used to determine differences in CD10 expression between benign, borderline, and malignant tumors. One-way ANOVA test was used to determine whether the difference was significant. Significance was established at P<0.05. Results: In the 24 cases of benign phyllodes tumors, only four cases (16.7%) showed positive CD10 reactivity. Three cases (60%) out of five borderline phyllodes tumors showed positive CD10 reactivity, while four (80%) out of five cases of malignant phyllodes tumors showed positive CD10 staining. Conclusion: From these highly significant results, we believe that there is a strong correlation between CD10 expression and tumor grade, which could be an important observation that may have both diagnostic and prognostic implications as well as promising potential target for development of novel therapies.

ABSTRACT

El tumor Phyllodes de mama es un tumor poco frecuente que se engloba dentro de los tumores fibroepiteliales de mama, con un amplio abanico de presentación clínica y comportamiento biológico. Se clasifican en benignos, borderline o malignos, en base a factores histológicos. Las formas menos agresivas o benignas presentan un comportamiento similar al de los fibroadenomas, sin embargo las formas malignas suelen presentar un comportamiento más agresivo. El pronóstico de este tipo de tumor es favorable, con una recurrencia local del 15 por ciento de forma global y recurrencia a distancia entre 5-10 por ciento. El tratamiento se basa en la escisión quirúrgica de la lesión, acompañada de radioterapia e incluso quimioterapia en las formas más agresivas. Presentamos la revisión de 13 casos clínicos de esta entidad diagnosticados en nuestro centro entre 2001-2009.


Phyllodes tumor of the breast is a rare tumor, which is part of fibroepithelial breast tumors with a wide range of clinical presentation and biological behavior. They are classified into benign, borderline or malignant based on histologic factors. The less aggressive or benign forms show a more behavior to that of fibroade-nomas, but malignant forms usually show a more aggressive behavior. The prognosis of this tumor is favorable, with local recurrence in 15 percent overall and distant recurrence between 5-10 percent globally. The treatment relies on surgical excision of the lesion accompanied by radiotherapy and chemotherapy even in the most aggressive. We present a review of 13 cases of this entity diagnosed in our center between 2001-2009.

ABSTRACT

Introduction: The phyllodes tumor (PT) of the breast is a rare disease of unknown origin. Despite its classification into benign, borderline and malignant, their behavior tends to be uncertain. Because of this, treatment remains controversial. Objective: To describe the management of the FT in breast pathology unit of our hospital and their outcomes. Material and Methods: We retrospectively reviewed the files of the patients with PT, operated in our hospital between 2001 and 2008. We analyzed the clinical characteristics, diagnostic studies, treatment and outcomes. Results: During this period 12 patients were operated. The ave-rage age was 42 +/- 15.2 years (16-64) and usually the form of presentation was painless palpable nodule. Both mammography and ultrasound were unable to suggest the diagnosis. Eight patients had core biopsy, which revealed the diagnosis of PT in 5, while in the other 3 was fibroadenoma. All patients underwent a partial mastectomy. The biopsy showed six benign, two borderline and two malignant PT. The latter two patients received adjuvant radiotherapy. At the end of this study, 2 patients had relapsed at 12 and 30 months (borderline and benign, respectively). There were no cases of lymphatic or distant metastases. Conclusions: The PT has a low frequency of presentation and preoperative diagnosis is difficult, so we recommend a core biopsy, but it can confuse with fibroadenoma. The management with partial mastectomy and negative borders had a recurrence rate of 18 percent in this series.


Introducción: El tumor filoides (TF) de la mama es una patología poco frecuente y origen desconocido. A pesar de su clasificación en benignos, borderline y malignos, su comportamiento tiende a ser incierto. Debido a esto su tratamiento sigue siendo controversial. Objetivo: Describir el manejo del TF en la unidad de patología mamaria del Hospital San José y sus resultados. Material y Método: Se revisaron las fichas de las pacientes con diagnóstico de TF, operadas en nuestro hospital entre los años 2001 y 2009. Se analizaron las características clínicas, estudios diagnósticos, tratamiento y resultados. Resultados: Durante este período se operaron 12 pacientes. El promedio de edad fue 42 +/- 15,2 años (16-64) y habitualmente la forma de presentación fue nodulo palpable indoloro. Tanto la mamografía como la ecografía fueron incapaces de sugerir el diagnóstico. Ocho pacientes tenían biopsia core, la cual evidenció el diagnóstico de TF en 5, mientras que en las otras 3 resultó fibroadenoma. Todas las pacientes fueron sometidas a mastectomía parcial. En seis pacientes resultó ser TF benigno, en dos borderline y en dos maligno. Estas últimas dos pacientes recibieron radioterapia adyuvante. Al término de este estudio 2 pacientes habían recidivado a los 12 y 30 meses (borderline y benigno respectivamente). No hubo casos de metástasis linfáticas ni a distancia. Conclusiones: El TF tiene una baja frecuencia de presentación, su diagnóstico preoperatorio es difícil recomendándose la biopsia core, sin embargo, suele confundirse con el fibroadenoma. El manejo con mastectomía parcial y bordes negativos tuvo una recidiva del 18 por ciento en esta serie.

ABSTRACT

O tumor phyllodes geralmente é benigno, muito raro, correspondendo a menos de 1% dos tumores fibroepiteliais da mama. O tratamento é cirúrgico e a taxa de recidiva, alta. Relatou-se o caso de uma paciente com tumor phyllodes benigno gigante, com infiltração de músculos peitorais e parede torácica, ulcerado, sangrante, submetida a tratamento cirúrgico emergenciado no Hospital Erasto Gaertner, em Curitiba, por mal estado geral, anemia intensa e infecção local. Evidenciou-se, pela apresentação desse caso, dificuldade em se apresentar terapêutica definitiva devido à manisfestação clínica atípica de tumor phyllodes benigno, caracterizado por lesão de grandes dimensões, de características invasivas, com comprometimento extenso da parede torácica, sem relatos prévios na literatura. O tratamento conservador nesse caso consistiu em mastectomia simples com ressecção em bloco dos músculos peitorais e preservação da parede torácica, contrastando com a literatura, em que a discussão entre cirurgia radical e conservadora inclui apenas relatos de mastectomia simples e ressecção da lesão com margens respectivamente.


The phyllodes tumor is normaly benignant and rare, accounting for less than 1% of the breast tumors. The treatment is surgical and the recurrence is high. We report the case of a patient with benignant, giant phyllodes tumor, with infiltration of the pectorales muscles and thoracic wall, ulcerated, bleeding, treated by emergency surgecal at the Erastus Gaertner Hospital in Curitiba, because of bad general state of the patient, acute anaemia and local infection.We show the difficulty to present the definitive therapeutic because of the atypical clinical manifestation benignant phyllodes tumor, caracterized by a big and invasive lesion, with infiltration of the thoracic wall, without prior report at the literature. The conservative treatment in this case was simple mastectomy with resection of the pectorales muscles and preservation of the thoracic wall, that contrast with the literature, whose discussion between conservative surgery just include reports of simple mastectomy and resection of the lesion with margin respectively.

ABSTRACT

We report a 65 year-old man with a large cystic phyllodes tumor of the prostate. The patient complained of abdominal discomfort and had a soft palpable mass. Computer tomography showed a solid and cystic mass in the pelvic fossa; the mass was adjacent only to the prostate. We excised the mass. Microscopic findings of the mass showed hyperplastic epithelium lined cysts with leaf-like intraluminal epithelia lined stromal projections, less than 2 mitotic counts/10 HPF, low-to-moderated cellularity, and mild-to-moderate cytoplasm atypia. The pathological findings were consistent with a phyllodes tumor of the prostate, a low-grade tumor. Twenty-eight months after the operation, the patient was well with no recurrence or metastases.

ABSTRACT

Presentamos un informe de una patología quirúrgica infrecuente y descripción de un caso clínico visto en el servicio de patología mamaria del Hospital Oncológico “Padre Machado”. Paciente femenina de 48 años de edad a la cual se le diagnosticó un tumor Phyllodes benigno de mama derecha, se le realizó mastectomía simple de la mama cuya biopsia definitiva reportó: tumor Phyllodes maligno de alto grado con extensas áreas de necrosis e infiltración a la piel, se observaron áreas de tumor de bajo grado y otros de alto grado, la inmuhistoquímica concluyó: tumor Phyllodes receptores de estrógenos y progesterona con patrón de inmunomarcaje normal, Her-2/neu negativo. El tumor Phyllodes maligno es la neoplasia no epitelial de la mama más frecuente y la cirugía es considerada el pilar fundamental en el tratamiento de esta patología, no existiendo un consenso actualmente sobre el tipo de cirugía debido a la poca incidencia de esta patología.


We presented a report of infrequent surgical pathology and description of a clinical case seen in service of mammary pathology of Oncological Hospital Father Machado. A feminine patient 48 years old which diagnose benign Phyllodes tumor of the right breast, simple mastectomy was made to her whose definitive biopsy report: Malignant tumor Phyllodes of high degree, with extensive areas of necrosis and infiltration to the skin, deep margin with evidence of neoplasia, were observed areas of tumor low degree and others of high degree, the immunohistochemical conclude: Phyllodes tumor, estrogen receivers and progesterone with pattern of normal immunomarcaje, HER-2/neu negative. The malignant tumor Phyllodes is the most frequent no epithelial neoplasia of the breast, and the surgery is considered the fundamental pillar in the treatment of this pathology, not exist a consensus at the moment on the type of surgery, due to the little incidence of this pathology.

ABSTRACT

BACKGROUND: Phyllodes tumors occur with a frequency of 0.3- 0.9% and are rare in young women. Their clinical presentation is unilateral and behavior and management are unclear. We present a phyllodes tumor in an 11-year-old female and we reviewed the literature regarding this pathology. CASE REPORT: We present the case of an 11-year-old female with a diagnosis of phyllodes tumor. Her disease began 4 months previously. We made an incision biopsy followed by simple mastectomy. Histological report demonstrated benign phyllodes tumor. The patient is currently disease free after 1 year. CONCLUSIONS: Small phyllodes tumors can be excised with a 1-cm surgical border, whereas larger phyllodes tumors are treated with simple mastectomy. Precise pathological evaluation is necessary to plan a better surgical approach and to determine recurrence possibility.

ABSTRACT

To determine the clinical and histopathological pattern, surgical protocol and need of adjuvant therapy for phyllodes tumour of breast Case series. Surgical department of Liaquat University Hospital Jamshoro, from November 2000 to October 2006. All female patients with phyllodes tumor of breast diagnosed after triple assessment were included. Non probable purposive sampling technique was used. Female having carcinoma breast were excluded. After taking consent data related to age, parity, site, size of tumor, treatment options, histopathology and metastatics work up done [in case of malignant disease]. Patients were advised follow up for minimum period of two years. Data was collected on proforma and analysed by SPSS version 10. A total of 35 patients with phyllodes tumor were studied. Out of these 23[67.5%] were benign, 5[14.3%] were borderline and 7[20%] were malignant. Mean age was 24 years. All patients were assessed by triple assessment. Nine[25.7%] patients had lumpectomy and 26[74.3%] underwent mastectomy. Patients with proven malignancy and borderline disease on histopathology were submitted for adjuvant chemoradiotherapy. Patients were followed for minimum period f two years. There was one recurrence after lumpectomy among benign disease [16.66%] while there was no recurrence after mastectomy with or without chemoradiotherapy. Phyllodes tumor must be vigorously treated with wide local excision or mastectomy followed by adjuvant chemoradiotherapy in malignant or borderline tumor to minimize recurrence

ABSTRACT

Antecedentes: El tumor phyllodes (TP) es un tumor poco común y aunque el 34,5-63,7 por ciento son benignos, el resto tienen un comportamiento borderline o maligno. Caso clínico: Paciente de 47 años derivada a nuestro centro para valoración por TP recidivante operado previamente tres veces con el resultado de TP de bajo grado con márgenes afectados. Al llegar a nuestro centro presenta un nódulo subcicatricial que se trata mediante escisión con el diagnóstico anatomopatológico de osteosarcoma osteoblástico de alto grado NI/ IV. Al estar con los márgenes afectados se trata posteriormente con cuadrantectomía más quimioterapia. Al terminar el tratamiento se objetivan en el TC torácico múltiples nódulos pulmonares compatibles con metástasis y se decide iniciar quimioterapia con otro esquema pero la paciente no responde y fallece por complicaciones derivadas de la progresión de su enfermedad pulmonar. Discusión: La cirugía es la base del tratamiento del TP, siendo la escisión local con márgenes suficientes, superiores a 1 -2 cm, el tratamiento de elección. La enucleación tumoral se considera insuficiente. La afectación tumoral de la axila ocurre en menos de 5-10 por ciento de las pacientes por lo que la exploración quirúrgica de la axila no se recomienda de rutina. Conclusión: La transformación osteosarcomatosa es una situación poco común, pero una cirugía incompleta en un TP maligno permite la desdiferenciación del componente estromal en sarcoma, incluso si el tumor inicial es de bajo grado. El pronóstico se ensombrece mucho, sobre todo si la transformación sarcomatosa contiene componentes heterólogos, como en este caso.


Background: Phyllodes tumor (TP) is a rare tumor. The majority of them have been described as benign, with the reminder divided between borderline and malignant tumors. Case description: 47-year-old patient derived to our hospital to evaluate a recurrent TP after three local failures. Surgical removal of tumor had positive margins in the previous surgeries. She presented to our service with a nodule in the scar that was resected. The pathology diagnosis revealed a poor differentiated osteosarcoma. As surgical margins were cióse, the treatment was completed with a wide local reexcision and adequate surgical margins plus chemotherapy. Multiple pulmonary nodules compatible with metastasis were targeted in the thoracic TC during follow-up and another chemotherapy scheme was initiated. The patient did not respond and died due to the progression of her pulmonary disease. Discussion: Surgical removal is the mainstay of TP treatment and wide excision with adequate margins superior to 1 -2 cm remains the treatment of choice. Lymphatic spread is uncommon and axillary metastases occur in less than 5-10 percent of patients, and therefore routine axillary dissection is not necessary. Conclusion: An incomplete resection in a malignant TP favours stromal overgrowth and sarcomatous transformation, which has very poor prognostic features.

ABSTRACT

Introducción: Los tumores filodes mamarios son neoplasias poco frecuentes habitualmente benignas. El diagnóstico diferencial principal es el fibroadenoma. El objetivo de este trabajo es caracterizar clínica e histopatológicamente a 39 mujeres tratadas en nuestro hospital. Material y Método: Estudio retrospectivo y descriptivo de fichas clínicas e informes histopatológicos de mujeres con tumores filodes de mama en el Hospital de Valdivia entre los años 1985 y 2006. Resultados: La edad promedio de las pacientes fue 44.4 años (extremos: 20 y 66 años). El tamaño promedio del tumor fue 8.3 cm (extremos: 2 y 28 cm). En 27 se realizó mamografía y en 13 ecotomografía, exámenes que orientaron al diagnóstico. Se obtuvo citología en 20 casos, siendo en 5 compatible con tumor fibroepitelial. El diagnóstico preoperatorio fue correcto en 23 pacientes. El tratamiento fue quirúrgico practicándose 29 mastectomías parciales, 7 mastectomías simples, 1 mastectomía simple extendida, 1 mastectomía de aseo y 1 mastectomía subcutánea. La histopatología concluyó 32 tumores benignos, 3 potencialmente malignos y 4 malignos. Un tumor maligno con margen infiltrativo y sobrecrecimiento estromal desarrolló metástasis pulmonares. El seguimiento promedio es 70 meses, registrándose una recidiva local y una metástasis pulmonar. Conclusiones: El diagnóstico de tumor filodes se sospecha en masas mamarias voluminosas circunscritas sin compromiso de linfonodos regionales. El tratamiento quirúrgico es efectivo siempre que se reseque la totalidad del tumor y un margen de tejido sano.
