Palmoplantar keratoderma (PPK) constitutes a heterogeneous group of disorders characterized by thickening of the palms and the soles of individuals who are affected. Woolly (dense, rough, and bristly) scalp hair is present at birth. Patients have an increased susceptibility to developing carcinoma of the esophagus (95% chance by age 65 y). There is characteristic involvement of the Achilles tendon. Late neurosyphilis occurs decades after infection. Patients commonly report pruritus. Cardiomyopathy with alopecia and palmoplantar keratoderma (CAPK) is caused by a JUP mutation.

Increased skin fragility may lead to skin splitting following trauma. PPK caused or exacerbated by water may improve with iontophoresis or botulinum toxin.Careful selection of footwear and treatment of fungal infections are important.Dermabrasion may permit increased penetration of topical agents, and carbon dioxide laser treatment may be beneficial in persons with limited keratodermas.For severe and refractory keratoderma, consider surgery. Punctate PPK with spastic paralysis Hystrixlike ichthyosis-deafness (HID) syndrome The cornea bends light rays as a result of its curved shape and accounts for approximately two-thirds of the eye's total optical power, with the lens of the eye … Punctate PPK with guttate hypopigmentation and calcinosis cutis (Cole disease) Efficacy, tolerability, and safety of calcipotriol ointment in disorders of keratinization.
