Grover's disease treated with isotretinoin. Report of four cases

Grover's disease (transient acantholytic dermatosis; TAD), a disorder of unknown etiology, may resemble Darier's disease and frequently resists conventional therapies. The lesions can be extensive and pruritus can be a prominent feature. Four patients with Grover's disease were treated with isotretinoin. Three patients with relatively acute disease responded with remissions of up to 10 months after treatment. One patient with disease of 8 months' duration obtained partial relief but experienced a relapse when medication was stopped.
