Proliferative myositis is a rare tumor that rapidly grows in muscles. A 60-year-old male patient with a firm chest wall tumor suggestive of a malignant lesion was referred to our clinic. The tumor was surgically resected after the confirmation of its benignity by frozen sections. The histological findings confirmed the diagnosis. In conclusion, proliferative myositis is an unusual, benign, pathological entity. Its clinical and radiological features may, however, simulate a malignant process, and a simple local excision is satisfactory for diagnosis and treatment.
