How do i treat grover disease?

Stay cool; see MD: Acantholytic dermatosis, sudden onset, unknown cause, transient or persistent, worse with heat so keep cool. Minimize itch with zyrtec and benadryl (diphenhydramine). First line treatment is prescription corticosteroid creams. If resistant to creams can use accutane, tetracyline, puva phototherapy. All treatments require seeing an experienced dermatologist who can confirm diagnosis and prescribe proper therapy.
