ABSTRACT

O fibroadenoma é um tumor benigno mais comum da mama. Trata-se de neoplasia mista com componentes epiteliais e estromais. As taxas de frequencia de malignização do componente epitelial do fibroadenoma referidas na literatura são muito baixas (0,3%). Na maioria das vezes o carcinoma associado a fibroadenoma apresenta-se no estágio in situ e tem bom prognóstico. O objetivo deste trabalho é descrever dois casos clínicos de carcinoma dentro de fibroadenoma atendidos no Hospital do Câncer – Instituto do Câncer do Ceará (ICC). Primeiro caso: paciente, 51 anos, submetida à excisão local de nódulo à direita. O anatomopatológico evidenciou fibroadenoma associado a carcinoma lobular in situ. Segundo caso: paciente 42 anos mastectomizada à esquerda em 2005, apresentou nódulo em mama direita cuja punção guiada por ultra-sonografia foi compatível com carcinoma. Submeteu-se a quadrantectomia com pesquisa de linfonodo sentinela. O estudo histopatológico demonstrou carcinoma ductal in situ dentro de fibroadenoma e em tecido periférico.


Fibroadenoma is the most common benign tumor of the breast. It is a mixed neoplasm with epithelial and stromal components. Malignancy rates for the epithelial component reported in the literature are very low (0.3%). Usually carcinomas associated with fibroadenomas are in the in situ stage and have a favorable prognosis. The objective of the present paper was to report two clinical cases of carcinoma arising in fibroadenoma in patients attending the Ceará Cancer Institute (Fortaleza, Brazil). Case 1: 51-year old patient submitted to local excision of node in the right breast. The pathoanatomical examination revealed fibroadenoma associated with lobular carcinoma in situ. Case 2: 42-year old patient with left breast mastectomized in 2005 presenting with node in the right breast. Ultrasound-guided biopsy compatible with carcinoma. The patient was submitted to quadrantectomy and sentinel lymph node biopsy. The histopathological examination revealed ductal carcinoma in situ arising in fibroadenoma and peripheral tissues.

ABSTRACT

Carcinoma ductal in situ é extremamente raro, com incidência aproximada de 7% de todos os carcinomas de mama, no sexo masculino. Nas mulheres, ao contrário, a freqüência do carcinoma ductal in situ ocorre em 20% a 25% de todos os casos de câncer de mama feminino. Em comparação com o carcinoma invasivo da mama, o prognóstico associado com o carcinoma in situ, em homem, é bastante favorável, não obstante a apresentação clínica ser variável. Os autores relatam um caso de carcinoma ductal in situ associado a ginecomastia em paciente de 48 anos, sem outros fatores de risco. Submetido a uma adenomastectomia à esquerda, o exame histopatológico revelou carcinoma ductal in situ, com provável infiltração incipiente. Posteriormente submeteu-se a mastectomia mais linfadenectomia axilar. O exame anatomopatológico, seguido de painel de imunoistoquímica da peça, mostrou tratar-se de ginecomastia associada a carcinoma ductal micropapilar in situ, sem comprometimento axilar.


Ductal carcinoma in situ, an extremely rare occurrence in male patients, accounts for approximately 7% of all breast carcinomas. In contrast, in women ductal carcinoma in situ occurs in 20% to 25% of all cases of female breast cancer. Compared to invasive breast carcinoma, the prognosis associated with carcinoma in situ in men is relatively favorable, in spite of variations in clinical presentation. The authors report a case of histopathologically confirmed ductal carcinoma ductal in situ, with early signs of infiltration, associated with gynecomastia in a otherwise healthy 48-year-old patient submitted to a left-sided adenomastectomy. The patient was subsequently submitted to mastectomy and lymphadenectomy of the axilla. An anatomic pathology examination followed by an immunoshistochemical panel revealed gynecomastia associated with micropapillary ductal carcinoma in situ without involvement of the axilla.
