Unna-Thost type of palmoplantar keratoderma: a case report

Non-epidermolytic variety of hereditary palmoplantar keratoderma with autosomal dominant inheritance characterised by uniform, thick, yellow hyperkeratosis over palms and soles was first described separately by Thost and Unna and named as Unna-Thost Keratoderma. We present a case of Unna-Thost keratoderma in a 9 year old male child who presented with waxy, thick, yellow palms and soles with fissures and contractures in hands.
