Myxoid soft tissue tumors consist of a heterogeneous group of mesenchymal neoplasms with a hallmark of the abundant extracellular myxoid matrix. Intramuscular myxomas are rare benign tumor affecting the musculoskeletal system. The common sites include the thigh, upper arm, calf, and the buttocks. Magnetic resonance imaging is the radiological modality of choice in diagnosing these cases, while tissue biopsy is the gold standard.
A 70-year-old male presented to orthopedics out-patient department with complaints of a humongous swelling engulfing his right thigh all around. The gradual and progressive appearance of burning sensations and rest pain around the affected area with difficulty in bearing weight, over the past 6-7 months forced him to seek medical attention. Biopsy and imaging were performed followed by final excision. The tumor was removed En-bloc and post-operative period was uneventful. The patient did not show any signs recurrence and was asymptomatic until the final followup of 26 months.
Myxomatous swelling mimics an intramuscular lipoma, sarcoma, hematoma, or a hemangioma and must be carefully evaluated. En-bloc excision without spillage is the treatment of choice which ensures long and lasting recovery.
