BACKGROUND Porokeratosis is characterised by one or more atrophic patches surrounded by a distinctive peripheral keratotic ridge, typically found on sun-exposed areas, with several clinical variants and typical histological findings. Despite ultraviolet radiation, varies antibody - related autoimmune disease treated with systemic steroids and other immunosuppressive conditions such as chronic l...

Porokeratisis is a specific keratinization disorder. The presence of cornoid lamella is histologically characteristic of the disorder. This report describes a 23-year-old male patient with multiple porokeratotic lesions with bilateral symmetric localization on the ala of the nose, which may be a rare variant of porokeratosis.

Porokeratosis is a genodermatosis characterized by abnormal epidermal keratinization with the histological feature of cornoid lamella. There are many clinical variants, but two or more of these variants rarely occur in a single patient. This variation in clinical presentation may be due to the different phenotypic expression of a common genetic abnormality or may be the consequence of abnormali...

Background and objective: Renal transplantation is an appropriate treatment for end stage renal disease and helps prolongation of patients survival with better quality, but immunosuppressive drugs that are used for inhibition of rejection after transplantation may cause some adverse effects in other organs such as the skin. Apparently, early recognition of those side effects and their app...
