Fibromatosis of the breast mimicking carcinoma at mammography

Abstract
Fibromatosis (extra-abdominal desmoid) presenting as a breast mass is a rare lesion. We have been able to find 42 cases in the literature (Adair & Herrmann, 1946; Ali et al, 1979; Bogomoletz et al, 1981; Cameron & Adair, 1965; Das Gupta et al, 1969; Gump et al, 1981; Haggitt & Booth, 1970; Hunt et al, 1960; Kalisher et al, 1976; Nichols, 1923; Norris & Taylor, 1968; Pearman & Mayo, 1942; Prior & Sisson, 1954; Rosen et al, 1978; Schremmer, 1971; Simpson et al, 1964; Zayid & Dihmis, 1969). In some of these cases the patient underwent preoperative mammography (Bogomoletz et al, 1981; Gump et al, 1981; Haggitt & Booth, 1970; Kalisher et al, 1976; Schremmer, 1971). We present a patient with a breast lesion which clinically as well as radiographically mimicked carcinoma, but which on histopathological examination proved to represent fibromatosis. A 28-year-old woman was treated in August 1978, a few months post partum, with incision and drainage of a purujent mastitis in the upper lateral quadrant of her left b...
