Proliferative myositis is a rare, self-limiting, benign disease. Its diagnosis can be difficult and in many cases is not confirmed until after surgical resection. Herein, we report a case of proliferative myositis of the right brachioradialis in a 64-year-old man. The patient presented with a rapidly growing, painless mass in his right forearm. Magnetic resonance imaging and fine-needle aspiration biopsy led to a diagnosis of proliferative myositis. Complete surgical resection of the mass was performed. Postoperative pathological examination confirmed the diagnosis. To the best of our knowledge, this is the first report of proliferative myositis in the right brachioradialis. Fine-needle biopsy is helpful in the diagnosis of proliferative myositis, thus avoiding unnecessary surgical trauma and costs.
增殖性肌炎是一种罕见的、自限性的良性疾病。其诊断可能较为困难，在许多情况下直到手术切除后才能确诊。在此，我们报告一例64岁男性右侧肱桡肌增殖性肌炎病例。患者右侧前臂出现一个迅速生长的无痛肿块。磁共振成像和细针穿刺活检确诊为增殖性肌炎。对肿块进行了完整的手术切除。术后病理检查证实了诊断。据我们所知，这是右侧肱桡肌增殖性肌炎的首例报告。细针活检有助于增殖性肌炎的诊断，从而避免不必要的手术创伤和费用。
