Lipid-rich carcinoma of male breast in Chinese: a case report and literature review.

Lipid-rich carcinoma of the breast is a rare variant of breast cancer, especially in males. Herein we report a case occurring in a 54-year-old male patient, who presented with a noticed painless, pea-sized lump in his left breast. Clinical examination and mammography suggested malignancy. Subsequent modified radical mastectomy revealed the diagnosis of lipid-rich carcinoma. To our knowledge, this subtype of mammary carcinoma is unprecedented in Chinese males in literature.
