A healthy 9-year-old girl presented to our dermatology department with multiple spiky keratotic projections on her palms and fingers since the age of 11 months. The patient described only occasional pruritus. Her mother and grandfather also had these keratotic lesions on their palms and soles. Skin examination revealed multiple 1 to 2 mm spiny papules and hyperkeratotic plugs symmetrically involving the palms as well as the sides of several digits (Figures 1 and 2). A punch biopsy specimen is demonstrated (Figures 3 and 4).
