POROKERATOSIS OF MIBELLI – A CASE REPORT
Porokeratosis are the result of a clonal proliferation of keratinocytes. About six clinical variants were des- cribed to date, sharing the histological feature of cornoid lamella in the stratum corneum.
The authors report a porokeratosis of Mibelli in a 27-year-old black female appearing in childhood successfully treated with a topical retinoid. Common manifestations of a rare dermatosis are presented with emphasis to the role of histo- pathology in the diagnosis. Porokeratosis of Mibelli is a chronic and progressive dermatosis, rarely with spontaneous remission. Malignant degeneration has been described with a reported incidence of 7%, with highest malignant trans- formation into squamous cell carcinoma, therefore the importance of regular skin checks.
