Dermatomyositis (DM) or polymyositis (PM) are possibly considered to have an association with malignancies. We describe a case of dermatomyositis in which (18)F-fluorodeoxy glucose (FDG)positron emission tomography (PET) was able to detect cancer recurrence earlier than any other modality in a patient with a history of primary pleural lymphoma, a very rare condition of malignancy. Further, a typical finding of dermatomyositis is diffuse hypermetabolism in the bilateral proximal shoulder and pelvic girdle areas was shown on (18)F-FDG PET, which can implicate the inflammatory process in the skeletal muscle in dermatomyosistis. This case well illustrates the characteristic (18)F-FDG findings of dermatomyositis as well as a capability of (18)F-FDG PET in detection of recurrence of lymphoma, even in a rare condition.
皮肌炎（DM）或多发性肌炎（PM）可能被认为与恶性肿瘤有关。我们描述了一例皮肌炎病例，在一名有原发性胸膜淋巴瘤病史（一种非常罕见的恶性肿瘤情况）的患者中，（18）F - 氟脱氧葡萄糖（FDG）正电子发射断层扫描（PET）比任何其他检查手段都能更早地检测到癌症复发。此外，（18）F - FDG PET显示皮肌炎的一个典型表现是双侧近端肩部和骨盆带区域弥漫性代谢增高，这可能与皮肌炎患者骨骼肌中的炎症过程有关。该病例很好地说明了皮肌炎的特征性（18）F - FDG表现以及（18）F - FDG PET在检测淋巴瘤复发方面的能力，即使在罕见情况下也是如此。
