Keratosis pilaris.

Keratosis pilaris, or 'plucked chicken skin', is a very common condition. It is caused by keratin accumulation in the hair follicles. Although mild cases of the condition can be considered to be a normal variant, it can lead to multiple appointments with general practitioners and dermatologists. In rare cases, keratosis pilaris can form part of specific syndromes or be associated with other diseases. The aim of this article is to give an overview of the different variants of keratosis pilaris and discuss the pathogenesis and treatment options.
