Giant Phyllodes Tumor in the Male Breast: A Rare Case Report and Review of Literature

Abstract

Cystosarcoma phyllodes, also known as phyllodes tumor, is a rare breast neoplasm that can occur in men, though it is more commonly seen in women. The majority of phyllodes tumors are benign, but some can be borderline or frankly malignant. These tumors are biphasic fibroepithelial in nature and are rare overall, accounting for less than 1% of all breast tumors. They are exceedingly uncommon in males, with only a few cases documented in the literature. Clinically, phyllodes tumors present as rapidly growing, painless masses in the breast. The standard treatment involves surgical excision—typically a lumpectomy—with a recommended margin of at least 1 cm of healthy surrounding tissue to reduce the risk of recurrence. We report a rare case of a giant cystosarcoma phyllodes of the breast in a 65-year-old male, managed successfully with a simple mastectomy.
