Bullous ichthyosiform erythroderma (BIE) is a rare disorder of keratinization (mutations in either keratin 1 or 10). It typically presents with fragile skin, which gives way to gradual evolutionof hyperkeratosis. Flaccid blisters, peeling, and superficial erosions at sites of minor trauma or friction are apparent within the first few hours of life. Yellow-brown, waxy, ridged or corrugated...

Focal acral hyperkeratosis (FAH) is a rare genodermatosis. FAH usually observed in the second or third decades of life, and it type palmoplantar keratoderma, heterogeneous group diseases characterized by abnormal incrassation palms soles. Although an autosomal dominant inher- itance, could also be sporadic. It known as variant Costa’s Acrokeratoelastoidosis (AKE). Its etiology not clearly there...

Palmoplantar keratodermas (PPKs) are a large group of disorders characterized by hyperkeratosis of palms and soles. They can be classified by their mode of inheritance, the morphology and distribution of the hyperkeratosis (diffuse, focal or punctate), the involvement of other ectodermal structures, the presence or absence of associated nonectodermal features and the morphological findings at l...

Brunauer-Fuhs-Siemens palmoplantar keratoderma, commonly known as striate palmoplantar keratoderma, is a rare, autosomally inherited disease of linear hyperkeratosis in which patient usually presents with conspicuous longitudinal hyperkeratosis on volar surface of hands and feet. Mutations in 3 genes namely desmoglein 1, desmoplakin and keratin 1, have been identified and held responsible for t...

DESCRIPTION We report the case of a 28-year-old man presenting to our hospital with refractory diffuse hyperkeratosis of palms and soles. He reported first appearance in early childhood. His first-born daughter also developed hyperkeratosis on palms and soles directly after birth. No other family member seems to be affected by similar skin lesions.
