Punctate Palmoplantar Keratodermas: Case Reports and A Review of the Literature and Terminology
ثبت نشده
چکیده
Keratodermas encompass a wide spectrum of disorders of keratinization that may be acquired or hereditary. We present two cases of focal acral hyperkeratosis (FAH), a subtype of punctate palmoplantar keratoderma. We review the literature and attempt to clarify the confusing classification of the heritable punctate palmoplantar keratodermas.

Palmoplantar keratodermas (PPKs) represent a diverse group of hereditary and acquired disorders characterized by hyperkeratosis of the skin on the palms and soles [1].

متن کاملUnilateral Linear Punctate Palmoplantar Keratoderma: A Case Report
Punctate palmoplantar keratoderma (PPPK) is a rare entity with an estimated prevalence rate of 1.17/100,000. PPPK usually presents with bilateral asymptomatic, tiny, hyperkeratotic punctate papules and plaques on the palmoplantar surface.

متن کاملIdentification of a locus for type I punctate palmoplantar keratoderma on chromosome 15q22-q24.
BACKGROUND The identification of the molecular basis of disorders of keratinisation has significantly advanced our understanding of skin biology, revealing new information on key structures in the skin, such as the intermediate filaments, desmosomes, and gap junctions. Among these disorders, there is an extraordinarily heterogeneous group known as palmoplantar keratodermas (PPK), for which only...
