A case of idiopathic granulomatous mastitis associated with erythema nodosum, arthritis, and reactive cough

Abstract

Idiopathic granulomatous mastitis (IGM) is a rare, chronic inflammatory disease of the breast.1-5 IGM most commonly affects young, healthy parous women and usually presents as an ill-defined breast lump simulating malignancy.1-5 On histopathology, noncaseating granulomas confined to the breast lobules are typically seen.1-5 We present a unique case of IGM that may be of interest to dermatologists who are not readily familiar with this condition.
