Intracystic Papillary Carcinoma in the Male Breast: A Case Report / 한국유방암학회지

Intracystic papillary carcinoma of the breast is a variant of ductal carcinoma in situ (DCIS) characterized by the presence of papillary carcinoma within a cystically dilated duct. DCIS of the male breast is an uncommon disease, accounting for approximately 7% of all male breast carcinomas. Most DCIS in men is of the papillary type. We experienced one case of intracystic papillary carcinoma in the right breast of a 49-yr-old male and report the case with a review of the literature.
