Abstract
Intramuscular myxoma is a rare, benign neoplasm of mesenchymal origin, affecting the musculoskeletal system. It usually develops after trauma. Herein, we report a rare case of an intramuscular myxoma which was located in the musculus gluteus maximus due to continuous intramuscular injections to the same buttock every 21 days for seven years. A 61-year-old male patient presented with progressive buttock pain with a two-year onset which worsened in the last three months. On magnetic resonance imaging, a well-circumscribed, septated, cystic mass was detected. The lesion was removed completely. Pathological examination revealed the diagnosis of intramuscular myxoma. After the excision, the patient was relieved of pain, and there was no recurrence at one-year postoperatively. In conclusion, continuous intramuscular injections may lead to development of intramuscular myxoma, similar to trauma etiology. Marginal resection of the mass can be curative in selected cases.
