[Cutaneous paraneoplastic syndromes]

Abstract

The authors list the really significant paraneoplastic cutaneous syndromes: acanthosis nigricans, paraneoplastic acrokeratosis, acquired ichthyosis (and eventually the "explosive" onset of seborrheic warts) and a special type of desquamative circinate erythema (erythema gyratum repens). The possible paraneoplastic character of other conditions is also discussed: dermatomyositis, necrosing vasculitis, autoimmune bullous conditions and pruritus "sine materia".
