The common manifestation of pompholyx is easily recognized by the clinician. Morphologic variants are known in which the predominant lesions are pustules or desquamation with or without erythema. A patient is described herein whose eruption was composed mainly of arciform, annular, and target-like vesicles. Pompholyx (bubble) is a preferred term because "dyshidrosis" denotes a dysfunction of sweating, which does not occur in this condition. The causes of this eruption have not been determined, but it is likely that a certain genetic predisposition and multiple environmental factors are responsible. Pompholyx should be considered in the differential diagnosis of eruptions with annular pattern.
汗疱疹的常见表现很容易被临床医生识别。已知存在形态学变异，其中主要病变为脓疱或脱屑，伴有或不伴有红斑。本文描述了一名患者，其皮疹主要由弧形、环形和靶样水疱组成。汗疱疹（水疱）是一个更合适的术语，因为“出汗不良”表示出汗功能障碍，而这种情况并不存在。这种皮疹的病因尚未确定，但很可能是由某种遗传易感性和多种环境因素导致的。在鉴别诊断具有环形形态的皮疹时应考虑汗疱疹。
