Granulomatous mastitis secondary to Corynebacterium requiring surgical intervention: a complicated diagnosis

Abstract

Corynebacterium species is a Gram-positive bacillus endogenous to human integument that has previously been associated with idiopathic granulomatous mastitis. The diagnosis and treatment of this bacteria may be complicated by inability to distinguish colonization from contamination and infection. We present an uncommon case of granulomatous mastitis associated with negative wound cultures requiring surgical intervention.
