Psoriasiform napkin dermatitis

Definition

A napkin eruption characterised by sharply marginated confluent erythema and scale in the napkin area. It is considered a component of infantile seborrhoeic dermatitis, the disseminated form of which may start in the napkin area. In some cases, however, the same clinical picture may eventuate into psoriasis (napkin psoriasis). The clinical picture is essentially identical.
