Sarcoidosis presenting initially as breast mass: report of two cases.

The cases of two patients who presented with breast masses suggesting carcinoma and no other clinical features of sarcoidosis are reported. Biopsies in both patients revealed noncaseating, epithelioid granulomas. Mycobacteria, fungi, and foreign material were not identified. In one of the patients, other sites of involvement were discovered five years later. These cases illustrate that sarcoidosis should be considered in patients with granulomatous breast disease, even without evidence of disease elsewhere.
