Mastite granulomateuse idiopathique : à propos de huit cas avec revue de la littérature

Abstract

Aim of the study. – The authors report eight cases of idiopathic granulomatous mastitis in which the epidemiological, clinical, diagnostic, therapeutic and prognostic features are discussed. Material and methods. – Retrospective study of eight cases registered among 2,000 breast anatomopathological study during 5-years period. Results. – The mead age was 44,3 years. Breast lump measuring 2,5 to 15 cm in size was noted at clinical examination. Mammography noted nodular opacities and ultrasonography showed hypoechoic nodules. Histological findings were consistent on granulomatous inflammation centred on mammary lobules. The inflammatory infiltrate was including leukocytes, lymphocytes, plasma cells as well as epithelioid and giant cells without caseous necrosis in the granuloma. Discussion and conclusion. – Idiopathic granulomatous mastitis is a rare entity. This entity can clinically mimic other breast mastitis disease. Diagnosis is assessed by histological analysis This disease can be treated with drugs and surgical excision of the lump. The prognostic of this chronic disease is favourable.
