Grover disease (transient acantholytic dermatosis) and piebaldism

A 35-year-old white man with lifelong stable white lesions on the anterior trunk and extremities presented with a pruritic papular eruption limited to the white patches. Results of a histologic examination led to a diagnosis of Grover disease (transient acantholytic dermatosis). To our knowledge, this article is the first to report an association between Grover disease and piebaldism or other depigmented disorders. We review the literature and speculate on the association between these conditions.
