한쪽 유방에서 동시에 발견된 피낭 유두상 암종과 관내 유두종에서 기원한 침윤성 관상피암: 증례 보고

Abstract

Encapsulated papillary carcinoma of the breast is rare, accounting for just 0.5% to 2% of all breast cancers. A histological upgrade from papillary lesion can also possibly occur, however, an upgrade to invasive ductal carcinoma has uncommonly been reported. Furthermore, to the best of our knowledge, there is no reported case of encapsulated papillary carcinoma and invasive ductal carcinoma arising from intraductal papilloma in the same breast. We report an extremely rare case of synchronous encapsulated papillary carcinoma and invasive ductal carcinoma arising from intraductal papilloma on the same breast with radiologic-pathologic correlation.
