Abstract
Lymphocytic mastitis is an uncommon fibro-inflammatory breast disease , found in association with some
auto-immune disorder e.g Type 1 diabetes , rheumatoid arthritis ,Sjogren's syndrome etc. The lymphocytic
mastitis is a benign lesion affecting young to middle aged females, involving one or both breasts. I am
reporting a rare case of lymphocytic mastitis in a 25 year old Indonesian patient with involvement of one
breast and having no known under lying risk factors.
