Abstract
Primary tuberculous pyomyositis is a rare manifestation of musculoskeletal tuberculosis especially in immunocompetent individuals without a focus of tuberculosis in the body and the underlying bone disease. It can cause a diagnostic dilemma for a physician and surgeon because of its similar presentation to soft tissue sarcomas, hematomas, and myopathies. We present a case of a 45-year-old immunocompetant gentleman with a thigh swelling with sepsis due to pyomyositis of the quadriceps requiring a multimodal management of drainage of abscess, debridement of devitalized muscle, antitubercular drugs, and physiotherapy. In a tubercular endemic country, a high index of suspicion is required to diagnose this disease which can be cured completely.
