Paraneoplastic importance of reactive dermatoses

Abstract

Reactive dermatoses may occur related to many underlying causes induding infections, inflammatory diseases, medications and malignancies. In the management of these dermatoses the investigation of underlying cause is crucial besides the therapy of dermatosis. In this review, mainly the paraneoplastic potentials of reactive dermatoses have been evaluated and additionally the etiology, follow-up and treatment have been discussed. Recent literature about figurated erythemas (erythema annulare centrifugum, erythema gyratum repens, necrolytic migratory erythema), neutrophilic dermatoses (Sweet's syndrome, pyoderma gangrenosum, subcorneal pustular dermatosis) and erythema nodosum have been scrutinized.
