Lipid-rich Carcinoma of the Breast: a Case Report

Abstract

Lipid-rich carcinoma is a rare variant and accounts for < 2% of all breast cancer diagnoses. We report a case occurring in a 53-year-old female. The patient presented with a painless, right breast mass. Clinical examination and mammography suggested malignancy. Subsequent modified radical mastectomy revealed the diagnosis of lipid-rich carcinoma. The morphological features, differential diagnosis and treatment along with a brief review of the literature are discussed in this article.

Lipid-rich carcinoma (L-RC) is a very rare variant of breast carcinomas with an aggressive clinical course and poor prognosis. It presents only 1% to 2% of all breast cases (1,2). It is classified as a specific variety of mammary carcinoma because the tumour cells possess abundant vacuolated cytoplasm which is strongly positive when stained for neutral fat. Aboumrad (2) first described it in 1963 as lipid-secreting carcinoma. However, Ramos and Taylor (1) renamed it as lipid-rich breast carcinoma. In China, the first case was reported in 1984 (3). Herein, we report a case of lipid-rich carcinoma occurring in a 53-year-old female patient, and the literature is reviewed.

Key Words:
