Annular pompholyx.

Abstract

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.
