皮肌炎是一种以对称性近端肌无力、肌痛和典型皮疹为特征的皮肤和肌肉的弥漫性炎症性疾病。1863年,Wanger首先称之为多发性肌炎,1891年由Unverricht命名为皮肌炎。本病和恶性肿瘤的关系早已提出,但由于缺乏深入的研究和大量的、可靠的统计学资料以佐证,这种关系仍不明瞭。本文收集近年来国内外文献共32篇,重点就这种关系作一简单的叙述。 Dermatomyositis is a diffuse inflammatory disease of the skin and muscles characterized by symmetrical proximal muscle weakness, myalgia and a classic rash. Wanger first called polymyositis in 1863 and dermatomyositis in 1891 by Unverricht. The relationship between the disease and malignant tumors has long been proposed, but the relationship remains unclear due to a lack of in-depth research and a large body of reliable statistical data. This article collects a total of 32 domestic and foreign literature in recent years, focusing on this relationship for a simple description.
