摘要IgG4相关性疾病是近年来提出的一种新病种,本病可累及人体任何组织和器官.IgG4相关性疾病的显著特征为血清IgG4水平升高以及多种器官和组织中IgG4阳性浆细胞浸润.近年来发现,IgG4相关性疾病可有皮肤改变,皮损可表现为多种皮肤病的症状,包括Mikulicz病、皮肤浆细胞增多症、假性淋巴瘤、血管淋巴样增生伴嗜酸细胞增多和木村病等.IgG4相关性疾病患者对系统糖皮质激素治疗反应较好.

abstractsImmunoglobulin G4 (IgG4)-related disease is a recently proposed entity, and can affect any tissue or organ in the human body.It is characterized by increased serum levels of IgG4 and infiltration of abundant IgG4-positive cells in various organs and tissues.Recent studies have found that IgG4-related disease may present with various skin manifestations, such as Mikulicz's disease, cutaneous plasmacytosis, pseudolymphoma, angiolymphoid hyperplasia with eosinophilia and Kimura's disease.Systemic glucocorticoids are effective for the treatment of IgG4-related disease.
