Grover's disease in patients with chronic renal failure receiving hemodialysis: clinicopathologic review of 4 cases

In 4 patients undergoing hemodialysis for chronic renal failure, a transient or persistent, papular and keratotic eruption developed on the trunk and arms. Histologic examination disclosed focal acantholysis with dyskeratosis. The lesions were clinically and histologically indistinguishable from those of Grover's disease. A possible association with Grover's disease and chronic renal failure and/or hemodialysis is postulated. Possible implicated pathogenic mechanisms are discussed. We suggest that Grover's disease should be included in the differential diagnosis of cutaneous eruptions in patients with chronic renal failure.
