It presents with thickening of the skin of the palms and/or soles which may be diffuse (involving most of the palms and soles) or focal (localised mainly to pressure areas)

Alerts and Notices Synopsis Palmoplantar keratoderma (PPK) is thickening of the palms and/or soles that cannot be attributed to friction alone. Cases are either inherited or acquired. Heritable PPKs are identified by the presence of a family history and childhood onset; they may manifest in isolation, as the defining feature of a syndrome, or as a minor aspect of a syndrome (eg, congenital. Histologically, the papules demonstrated hyperkeratosis, without columns of parakeratosis. A diagnosis of type I hereditary punctate keratoderma (Buschke-Fisher-Brauer disease) was made. This condition, which is classified as one of the three hereditary forms of punctate palmoplantar keratoderma, is an autosomal-dominant condition with variable.
