Palmoplantar keratoderma | Primary Care Dermatology

Palmoplantar keratoderma, non-epidermolytic, focal or diffus

  1. A dermatological disorder characterized by non-epidermolytic abnormal thickening of the skin on the palms and soles. Diffuse palmoplantar keratoderma is characterized by uniform involvement of the palmoplantar surface, while the focal form consists of localized areas of hyperkeratosis located mainly on pressure points and sites of recurrent friction
  2. Based on clinical and histopathological findings, diagnosis of Unna-Thost variety of Diffuse Non-epidermolytic Palmoplantar Keratoderma (NEPPK) was done. Both, the patient and her father have been prescribed topical tretinoin and emollients, and at present, they are under follow-up
  3. antly inherited condition traced to KRT1 and KRT16 keratins
  4. ant genodermatosis that clinically is indistinguishable from epidermolytic PPK other than tending to be milder, but does not show epidermolysis in biopsy sections

Clinical patterns. Clinically, three distinct patterns of palmoplantar keratoderma may be identified: diffuse, focal, and punctate. [1]:505: Diffuse. Diffuse palmoplantar keratoderma is a type of palmoplantar keratoderma that is characterized by an even, thick, symmetric hyperkeratosis over the whole of the palm and sole, usually evident at birth or in the first few months of life Palmoplantar keratoderma (PPK) is a group of skin conditions characterized by thickening of the skin on the palms of the hands and soles of the feet. PPK can also be a feature of various underlying syndromes. In rare forms of PPK, organs other than the skin may also be affected. PPK can be either acquired during the lifetime (more commonly) or inherited Palmoplantar keratoderma is also sometimes known as ' keratosis palmaris et plantaris'. Classification of keratodermas depends on whether it is inherited or acquired, and the clinical features. Diffuse keratodermas affect most of the palms and soles. Focal keratodermas mainly affect pressure areas Diffuse hereditary palmoplantar keratoderma associated with other abnormalities Deafness. Vohwinkel syndrome (MIM 124500) is an autosomal dominant keratoderma associated with 'starfish'-shaped thickening over knuckles, tight bands forming around fingers which sometimes result in amputation of the finger or toe affected (pseudoainhum), and deafness
