Grover's disease: 34 years on.

Grover's disease is an entity reported worldwide and recognized as a common disease since Grover first described it in 1970. Its cause remains obscure, but hospitalized, febrile and sun-damaged patients are particularly prone. It is frequently associated with some other skin diseases, including eczemas, psoriasis and solar keratoses. Acantholysis is the universal histological finding in all the varying clinical presentations. Treatment in the past has been ad hoc, but topical therapy, acitretin and phototherapy can suppress symptoms.
