Intracystic Papillary Carcinoma in the Male Breast: A Case Report
Abstract
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.
Fig 1
Ultrasonographic findings. This tumor is a 2.3×1.6 cm sized well marginated cystic mass with an internal fluid level (arrow) and an irregular solid component in the right subareolar area.
Fig 2
Fine needle aspiration cytology findings. There are two papillary structures consisting of a central core of stromal cells surrounded by layers of epithelial cells in a hemorrhagic background (H&E stain, ×100).
Fig 3
Gross specimen after excision. The tumor is a well-encapsulated round mass composed of friable solid tissue in a papillary pattern (arrow) and brown fluid.
Fig 4
Histopathologic findings (H&E stain A×100, B×200). Papillary proliferations of the tumor cells with a fibrovascular core within the cystically dilated duct are observed. The high power view shows the layering of tumor cells, loss of nuclear polarity, hyperchromasia and lack of myoepithelial cell layer.

Immunohistochemical stains of estrogen receptor is positive (A×200) and SMMHC is negative (B×200).
