Hailey - Hailey Disease.
Keywords:
Hailey-Hailey disease, acantholysis, pathologyAbstract
Hailey – Hailey disease (familiar benign pemphigus) is a genodermatosis, inherited as an autosomal dominant condition mapped to chromosome 3q21-q24.
It encodes a Ca2+pump implicated in the production the cadherins adhesion molecules. The main histologic characteristic is the acantholysis, responsible of the intraepidermal vesicles and bullae.
We report a typical clinical and histological case of the disease.
