DIAZ C, M. LORENA  ; ARANCIBIA H, PATRICIA; MOYANO S, LEONOR  y  BURGOS S, NELSON. Breast fibromatosis: Report of one case. Rev Chil Cir [online]. 2009, vol.61, n.4, pp.370-374. ISSN 0718-4026.

Desmoid tumors or fibromatosis, a rare lesion of the connective tissue, corresponds to 0.2% of breast tumors. It does not metastasize but has high local recurrence rates due to margin infiltration. The clinical presentation and imaging is almost indistinguishable from breast carcinoma. Diagnosis is histological and the treatment of choice is surgical excision. We report a 31 years old woman consulting for skin retraction in right breast, without previous history of trauma or surgery. Breast ultrasound showed an irregular nodule that extended into the skin. The mammogram showed a discrete retraction of the skin and increased density of adjacent subcutaneous tissue. An ultrasound guided percutaneous biopsy showed stromal fusocelular proliferation, suggesting a phyllodes tumor. A partial mastectomy was performed and the pathological study of the surgical piece showed a mesenchymal proliferation with infiltrative borders, consistent with breast fibromatosis.

Palabras clave : Breast fibromatosis; desmoid tumor; mammary nodule.
