Malignant myositis ossificans. A case report.
A patient presented with an ossifying thigh mass suggestive of myositis ossificans. He had no antecedent trauma to the area. The mass was found to be an ossifying soft tissue metastasis from an occult gastric adenocarcinoma primary. Malignancy, and especially metastatic malignancy, is rarely considered in the differential diagnosis of a radiographic presentation of myositis ossificans.
