Pyomyositis is a rare complication of chemotherapy. A 47-year-old woman with metastatic breast cancer, in whom pyomyositis developed after chemotherapy, is described. It was difficult to differentiate between pyomyositis and deep venous thrombosis early in her admission. Pyomyositis should be considered part of the differential diagnosis of deep venous thrombosis. This infection, after chemotherapy, usually is considered to be caused by neutropenia or immunodeficiency secondary to the cancer, or both. It is postulated that subclinical myopathy, secondary to the malignancy or drugs used in treating the malignancy, or both, may also predispose to pyomyositis.
脓性肌炎是化疗的一种罕见并发症。本文描述了一名47岁患有转移性乳腺癌的女性，她在化疗后发生了脓性肌炎。入院早期很难区分脓性肌炎和深静脉血栓形成。脓性肌炎应被视为深静脉血栓形成鉴别诊断的一部分。化疗后的这种感染通常被认为是由癌症继发的中性粒细胞减少或免疫缺陷，或两者共同引起的。据推测，继发于恶性肿瘤或治疗恶性肿瘤所用药物，或两者共同作用的亚临床肌病也可能易患脓性肌炎。
