Muscle Mass in the Calf as a Presenting Symptom of Sarcoidosis / 대한류마티스학회지

ABSTRACT

Sarcoidosis is a multisystemic granulomatous disease of unknown cause. Lung, skin, eye, liver and lymph nodes are commonly affected. But the nodular type of muscular sarcoidosis is rare. The nodular type can be presented with a soft tissue mass that may be confused with a tumor. Magnetic resonance imaging and muscle biopsy are useful methods for early diagnosis. Optimal management of nodular sarcoidosis is not well known, but surgical excision or corticosteroid may be considered as an initial management. We report a case of nodular muscular sarcoidosis as an initial manifestation of sarcoidosis in a 56-year-old woman who was treated with corticosteroid therapy after surgical excision.
