Prevotella bivia: A Rare Cause of Zuska's Breast Disease.

Zuska's breast disease is a rare disorder leading to recurring subareolar abscess typically in obese patients with a history of smoking. The pathophysiology is a combination of ductal obstruction from squamous metaplasia and infection usually by anaerobic and gram-positive bacteria. Zuska's breast disease does not have a single standardized treatment partly attributed to the lack of physician awareness of the disorder. The initial management should include smoking cessation, anaerobic and gram-positive antibiotic coverage, and drainage of abscesses if present.
