Hyperkeratosis Palmaris et Plantaris, also known as palmoplantar keratoderma or palmoplantar keratosis, is a dermatological condition characterized by the abnormal thickening of the skin on the palms of the hands and soles of the feet. It is a type of hyperkeratosis, which refers to the excessive development of the outer layer of the skin (keratin), resulting in the formation of thickened, dry, and calloused areas.
The condition typically begins in childhood or adolescence and tends to be chronic, often persisting throughout the affected individual's life. It can present with various symptoms, including dryness and scaling of the palms and soles, rough and thickened patches of skin, and occasionally painful fissures or cracks. These symptoms can cause discomfort and impairment in daily activities such as walking or gripping objects.
Hyperkeratosis Palmaris et Plantaris can be inherited in an autosomal dominant or autosomal recessive manner, indicating that it may be passed on from generation to generation. In some cases, the condition can also occur sporadically without any familial history. The exact causes of this condition are not yet fully understood, but genetic mutations are thought to play a significant role.
Treatment options for Hyperkeratosis Palmaris et Plantaris primarily focus on managing and relieving symptoms, as there is no known cure. This may include regular and intensive moisturization, the use of topical keratolytic agents to reduce excessive keratin production, and the application of specialized creams or ointments. In severe cases, more aggressive treatments such as surgical removal of the thickened skin or laser therapy might be considered. A dermatologist is typically consulted for proper diagnosis and treatment of this condition.
