Open Access Publication Congenital Hyperkeratosis of the Hand and Foot: Variances discovered in the clinical presentation of palmoplantar keratosis (PPK)

چکیده
Case presentations describing a congenital variation of palmoplantar keratosis are presented. The majority of these conditions are autosomal dominant with associated nail dystrophy. A variant condition is described with little palmar keratosis; however, finger nail and toe nail dystrophy is the most common identifying feature. Gene identification and treatment protocol are presented. Fortunately, these conditions are rare. A good knowledge of these conditions will help in proper diagnosis and treatment.

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. Clinically, our patient presented diffuse hype...

متن کاملKeratinization Disorders and Genetic Aspects in Palmar and Plantar Keratodermas.
Palmoplantar keratoderma (PPK) is a heterogeneous group of hereditary and acquired disorders characterized by abnormal thickening of the palms and soles. There are three clinical patterns: diffuse, focal, and punctuate. Palmoplantar keratodermas can be divided into the following functional subgroups: disturbed gene functions in structural proteins (keratins), cornified envelope (loricrin, trans...
متن کاملMutations in desmoglein 1 cause diverse inherited palmoplantar keratoderma phenotypes: implications for genetic screening
The inherited palmoplantar keratodermas (PPKs) are a heterogeneous group of genodermatoses, characterized by thickening of the epidermis of the palms and soles. No classification system satisfactorily unites clinical presentation, pathology and molecular pathogenesis. There are four patterns of hyperkeratosis - striate, focal, diffuse and punctate. Mutations in the desmoglein 1 gene (DSG1), a t...
متن کاملAutosomal recessive epidermolytic palmoplantar keratoderma.
Palmoplantar keratoderma (PPK) is a heterogeneous group of disorders. Epidermolytic PPK is a well delineated autosomal dominant entity, but no recessive form is known. Here we report two sons of phenotypically normal, consanguineous, Arab parents with features suggestive of PPK. They presented with patchy eczematous skin lesions followed by PPK and raised serum levels of IgE. Skin biopsy from t...
