A Case of Porokeratosis of Hands and Feet Turning into a Squamous Cell Carcinoma

摘要

Porokeratosis is comprised of heterogeneous group of diseases that inherited as autosomal dominant pattern. It is a disorder of keratinization characterized by one or more atrophic macules or patches, each surrounded by a distinctive hyperkeratotic, ridge-like border called a cornoid lamella. Multiple clinical variants of porokeratosis exist, some of them have genetic inheritance while others are acquired and malignant transformation occurs in a minority of cases. In Iraq, the inherited commonly described entities of porokeratosis are rarely seen, but every now and then localized forms like porokeratosis of the scrotum and other parts of the body were seen. In addition solar facial porokeratosis is an acquired disease not uncommonly seen in young females which disappear over time. The aim of the present report is to record an unusual case of localised porokeratosis of both hands and feet with multiple squamous cell carcinomas with negative family history.
