壊死像が目立った乳腺非浸潤性アポクリン癌の1例

An 88-year old woman had an approximately 20mm tumor in her left breast is described. We performed partial resection of her breast under local anesthesia because of her old age and found out to be an intraductal apocrine carcinoma with necrosis and histiocyte infiltration into the stroma leasion by histological findings. We made a wrong diagnosis as it was invasive ductal carcinoma by the preoperative mammography and ultrasonography findings. It might be due to those histological view. According to the immunostaining procedure, ER was positive and PgR was negative. There are 26 cases reports of intraductal apocrine carcinoma including this case in the Japanese literature. We found only 4 cases were described about intraductal necrosis in their sentences. And 3 cases of them have succeeded in treating by breast partial resection. We examined about this case and report with analyzing those previous literature review.
