Breast Fibromatosis

We report a case of fibromatosis of the breast in which both clinical and mammographic appearances were indicative of carcinoma. The patient was 46 years old Bahraini, obese woman who presented with a hard right breast mass. As fine needle aspiration (FNA) cytology did not reveal any malignant cells, a conservative local excision was performed. Fibromatosis should hence be considered in the differential diagnosis of patients presenting with hard breast lumps suspicious of malignancy. The differential diagnosis is discussed with review of the literature.
