Abstract
- Sarcoidosis is a systemic granulomatous disorder of unknown cause. The isolated noduar type muscular sarcoidosis without other systemic involvement is very rare in Korea. We report a case of sarcoidosis presented with myofasciitis. A 46-year-old man visited hospital with painful nodular swelling on the right arm for 1 month. We performed a humerus MRI and it revealed irregular shaped subcutaneous mass infiltrating along the fascial plane. The biopsy of triceps mass showed non-caseating granuloma of muscle and fascia. To find out the cause of granuloma, we checked chest CT scan and found out some enlargement of mediastinal lymph nodes. The biopsy also demonstrated non-caseating granulomas. It had no cancerous component and culture for microorganisms were all negative. He was diagnosed as sarcoidosis and given NSAID. On follow up evaluation, the size of mass was decreased.
