Acrokeratosis verruciformis.

We present a case of acrokeratosis verruciformis of Hopf in a 58-year-old woman with multiple, skin-colored, flat-topped, hyperkeratotic papules on the dorsal aspects of the hands and feet. Her lesions appeared at age 13 and her son developed similar lesions at about the same age. Acrokeratosis verruciformis of Hopf is a rare genodermatosis, which is distinct from keratosis follicularis; sporadic cases have also been described. Management options include cryotherapy, keratolytics, superficial ablation with CO2 or Nd:YAG lasers, topical retinoids, and acitretin.
