title: Myxoid liposarcoma of the breast in a 25-year-old female as a diagnostic pitfall in fine needle aspiration cytology: report of a rare case.
abstract: Primary sarcomas of the breast are extremely rare comprising less than 1.0% of all malignant tumors of the breast. It is even rarer to be reported in a 25-year-old female. This can cause a diagnostic dilemma not only for the clinician but also for the cytopathologist. A 25-year-old woman presented with a well defined firm, mobile lump in her right breast. With fine needle aspiration cytology (FNAC) and ultrasonography a diagnosis of fibroadenoma was made. The patient underwent lumpectomy. Histopathologically it was diagnosed as myxoid liposarcoma. This case is reported to highlight the fact that, even though rare in young females but the possibility of a breast lump being a myxoid liposarcoma does exist. This report discusses a primary myxoid liposarcoma of female breast, considers cytologic differential diagnoses with review of the relevant literature.
