Two Cases of Kyrle's Disease / 대한피부과학회지

ABSTRACT

Kyrle's disease is a rare disorder characterized by hyperkeratotic papules containing a central, cone-shaped plug on the extensor surface of the extremites. We describe two cases of Kyrle's disease. The first case is 65-year-old male patient. He had multiple pruritic hyperkeratotic papules with a central plug on both lower extremities. He has suffered from Diabetes mellitus for 20 years. The second case is 54-year-old male patient. He had multiple pruritic hyperkeratotic papules with a central plug on the back, upper and lower extremities. He has been suffered from Diabetes mellitus for 20 years and chronic renal failure for 6 months. Histopathologic findings showed central epidermal invagination filled with heavy keratotic, partly parakeratotic plug and basophilic debries. Many vacuolated cells and a few dyskeratotic cells were seen below the keratotic plug.
