A 50-year-old man who was a heroin addict developed bilateral, symmetrical swelling of the breasts as a result of injecting himself directly into the breasts for several years. Results of histologic examination of the breast tissue showed granulomatous inflammation and a foreign body reaction without gynecomastia or tumor. Liver and endocrine functions were generally normal.
