두피에 발생한 담관암 유래 궤양성 결절양 피부 전이암 1예

Abstract

Cholangiocarcinoma frequently metastasizes to several internal organs but rarely to the skin. We report a case of a cutaneous metastasis of cholangiocarcinoma in a 59-year-old female who had asymptomatic, firm, ulcerative nodules and papules on the scalp. She had been diagnosed with cholangiocarcinoma 3 years earlier, and histopathologic examination of the cutaneous lesion showed well differentiated tubular adenocarcinoma.
