Abstract:
Porokeratosis of Mibelli, a chronic heritable disorder of the skin, presents with characteristic histopathological features including cornoid lamella as a result of faulty keratinization. Amyloid deposits are characterized by the accumulation of ultrastructually fibrillar material and have been observed in inflammatory and tumoral skin diseases. Some cases of amyloid deposits in the upper dermis in various subtypes of porokeratosis have been reported, but no porokeratosis of Mibelli reports are available in Korea. We report a case of a 26-year-old woman with three verrucous hyperkeratotic plaque lesions on her right popliteal fossa with histological feature of hyperkeratosis, cornoid lamella, and dermal amyloid deposits.
