Diabetic muscle infarction (DMI) is a rare complication of diabetes mellitus. We report the first recorded case in Japan. A 45-year-old Japanese woman presented with severe pain in the left antero-medial thigh. She had a 14-year history of Type 2 diabetes mellitus (DM). She had first noticed pain in her left thigh after a walk 2 weeks prior to presentation. The pain worsened progressively. She noticed a firm mass in her left thigh. T2-weighted magnetic resonance imaging (MRI) demonstrated a high-intensity signal in the muscle bulk of the anterior component of the left thigh. A needle biopsy of the mass showed necrosis. She was treated with bedrest and an antiplatelet agent. The mass disappeared 8 weeks after admission. DMI is a rare complication of poorly controlled diabetes mellitus. Twenty-seven cases with DMI have been reported in the English literature but we believe this is the first Japanese case with DMI.
糖尿病性肌肉梗死（DMI）是糖尿病的一种罕见并发症。我们报告了日本首例有记录的病例。一名45岁的日本女性出现左大腿前内侧严重疼痛。她有14年2型糖尿病（DM）病史。她在就诊前2周散步后首次注意到左大腿疼痛。疼痛逐渐加重。她注意到左大腿有一个硬块。T2加权磁共振成像（MRI）显示左大腿前侧肌肉块内有高强度信号。对肿块进行针吸活检显示有坏死。她接受了卧床休息和抗血小板药物治疗。入院8周后肿块消失。DMI是糖尿病控制不佳的一种罕见并发症。英文文献中已报道27例DMI病例，但我们认为这是日本首例DMI病例。
