Lichenoid folliculitis of the scalp in four patients with ichthyosiform skin disorders and cicatricial alopecia.

ABSTRACT

Ichthyosis is a heterogeneous group of inherited skin disorders characterized by a defect of keratinization. Patients diagnosed with lamellar ichthyosis (LI) and some ichthyosiform syndromes, such as the Conradi-Hünermann-Happle syndrome (CHHS), usually present with hair loss. Even though only few dermatologic complaints carry as many emotional overtones as hair loss, there are very few data available in the literature regarding scalp histopathological features in ichthyosis. A better understanding of scalp changes in such context may result in new therapeutic strategies that in turn would enhance patients' self-esteem and quality of life. The aim of this paper is to describe the scalp histopathological findings of four young patients with cicatricial alopecia three diagnosed as having LI and the fourth with CHHS.
