Mycobacterium Avium Infection in a Silicone-Injected Breast

: A case of atypical mycobacterial infection (M. avium intracellulare) in a silicone-injection augmented breast is described. The silicone injection may have been a contributing factor to the development of this unusual infection. Disseminated M. avium was present in this patient, with breast involvement being suggested by the rapid appearance and disappearance of localized areas of erythema and tenderness. Aggressive treatment of these breast infections while they are still localized may prevent systemic spread. Conventional incision and drainage of the breast abscess combined with multidrug treatment directed against M. avium is the recommended therapy.
