Cancer-related muscle diseases are usually paraneoplastic disorders. Dermatomyositis (DM) is a type of inflammatory myopathy that is strongly associated with a broad range of malignant disorders. The malignancy can occur before, concomitantly or after the onset of myositis. The malignancies most commonly associated with DM are carcinomas of ovary, lung, stomach, colorectal and pancreas, as well as non-Hodgkin's lymphoma. An association of DM with carcinoma of the gall bladder (GB) is extremely rare with only two previously reported cases in the literature. We report a case of carcinoma of GB with DM as the paraneoplastic manifestation.
癌症相关的肌肉疾病通常是副肿瘤性疾病。皮肌炎（DM）是一种炎性肌病，与多种恶性疾病密切相关。恶性肿瘤可在肌炎发作之前、同时或之后发生。与皮肌炎最常相关的恶性肿瘤是卵巢癌、肺癌、胃癌、结直肠癌和胰腺癌，以及非霍奇金淋巴瘤。皮肌炎与胆囊癌（GB）的关联极为罕见，文献中此前仅报道过两例。我们报告一例以皮肌炎为副肿瘤表现的胆囊癌病例。
