ABSTRACT

Porokeratosis is an inherited disorder of keratinisation which is characterized by brownish annular lesions with raised margins and atrophic centers. This raised margin corresponds to the characteristic „cornoid lamella‟ on histopathology. Dermoscopy aids to the diagnosis which is mainly clinical showing various features such as white peripheral rim, brown globules, red dots, white flakes etc. Here we report one such patient showing how dermoscopy acts as a definitive tool in the diagnosis of porokeratosis decreasing the need for more invasive procedures such as skin biopsy.
