A Case of Kyrle's Disease / 대한피부과학회지

ABSTRACT

We report a case of Kyrle's iisease occurring in a 60-year-old woman with chronic renal failure. The patient had multiple hyperkeratotic papules with a central plug on the back, and in the upper and lower extremities. Histopathological findings showed epidermal invagination filled with parakeratotic column and basophilic debris. Many dyskeratotic and vacuolated cells were present below the keratotic plug, and penetration of the parakeratotic column into the dermis was seen.
