Fibromatosis is an uncommon, relatively benign though locally infiltrating neoplasm consisting of well-differentiated fibroblasts surrounded by collagen bundles. In this paper we present a case of fibromatosis of the breast. The patient, a 25-year-old female, came to our hospital complaining of a lump in her right breast. A physical examination revealed a firm, nontender, mobile mass measuring 3 cm in the upper area of the right breast. A mammography of the right breast demonstrated heterogeneously dense fibroglandular tissue, and ultrasound revealed a partially poorly defined 2 cm hypoechoic mass with enhanced posterior-echo. Doppler ultrasound also showed the existence of peripheral palsatile blood flow. We suspected fibroadenoma and performed an excisional biopsy of the mass. A gross pathological examination showed a 2 cm firm, off-white specimen of fibroadipose tissue, Microscopic sections showed spindle cells surrounded by collagen bundles. The spindle cells had infiltrated the normal breast ducts. Fibromatosis of the breast is uncommon: of the 100 or so cases that have been reported, the sonographic features of only three have been described to date.
