A 3-Year Causative Study of Pompholyx in 120 Patients

Abstract

Our data confirm the existence of reactional pompholyx to interdigital-plantar intertrigos and endogenous reactions to metals or other allergens, but they mainly point at the unexpected importance of a so-called contact pompholyx in which cosmetic and hygiene products play a preponderant role compared with metals. The great frequency of atopic conditions, even if idiopathic pompholyx is not inferred as an equivalent of atopy, should lead to further causative investigations before undertaking more expensive or extensive treatments of refractory pompholyx.
