Isolated muscle mass as an initial presentation of sarcoidosis: a case report and discussion.

Sarcoidosis is a multisystemic inflammatory disorder of unknown etiology. It can present in various clinical forms. Involvement of muscles is common but isolated muscle mass, the only initial presenting complaint has never been reported. We report a 55-year-old white female who presented with a muscle mass, with no other clinical features of sarcoidosis. She was later found to have hilar lymphadenopathy and muscle biopsy confirmed the diagnosis of sarcoidosis. During clinical follow up patient remained stable without any medical intervention.
