Focal myositis, the much rarer clinical and pathological variant of polymyositis, is generally a benign inflammatory pseudotumor of skeletal muscle Thus far, only three cases have been reported in association with a neoplasm. We now describe a fourth case of localized gluteal myositis seen in a case of signet ring adenocarcinoma of the stomach occurring not as a paraneoplastic syndrome, as in the previously reported three cases, but as an immunoinflammatory response around metastatic cell foci in both the involved muscles and local lymphatics.
局灶性肌炎是多肌炎中较为罕见的临床和病理变体，通常是骨骼肌的一种良性炎性假瘤。迄今为止，仅有3例与肿瘤相关的病例报道。我们现描述第4例局限性臀肌炎，该病例发生于胃印戒细胞腺癌患者，并非如先前报道的3例那样作为副肿瘤综合征出现，而是作为受累肌肉和局部淋巴管中转移细胞灶周围的免疫炎症反应。
