Darier-Roussy Sarcoidosis Mimicking Metastatic Breast Cancer.

Subcutaneous sarcoidosis (also known as 'Darier-Roussy sarcoid') is a cutaneous condition characterized by numerous deep-seated nodules on the trunk and extremities. Coexistence of sarcoidosis and breast cancer are reported in the literature, but there will always be a chance of misdiagnosis. It is very crucial to obtain a tissue diagnosis of suspicious metastatic lesions.
