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.
