Mammary sarcoidosis: A rare case report.

Introduction: Sarcoidosis is an inflammatory, systemic, idiopathic disease characterized by multisystem involvement, of which mediastinal and pulmonary involvement is the most frequent. Mammary sarcoidosis is exceptional.

Case Presentation: We report the case of a 50-year-old, diagnosed with mediastinal and mammary sarcoidosis. Therapeutic abstention with clinical and radiological surveillance was recommended. The evolution was marked by a clear improvement (clinical and radiological).

Discussion: Mammary sarcoidosis is a rare anatomical and clinical entity which poses a problem of differential diagnosis with other granulomatous diseases and especially with breast carcinoma. The coexistence of systemic manifestations should lead to the discussion of sarcoidosis.

Conclusion: Mammary sarcoidosis involvement is rare and is manifested by a mass with a smooth or spiculated border, requiring the exclusion of malignancy.
