[Syndrome of giant deratoma of the feet (syndroma cornuum giganteum dedum)].

The syndrome of giant keratoma of the feet with disseminated keratotic papules on the thighs and legs, lack of fusion of the posterior arch of the L5, S1 vertebrae, varus deformity of feet and (congenital?) deformity of metatarsal bones and skeletal atrophy of feet, supernumerary 6th fingers and toes, extreme gothic palate, scanned speech, and low oscillometric values on the legs was described in a 28-year-old man. Good results were achieved after electrocoagulative removal of the keratomas and systemic treatment with Tigason and high doses of vitamin E.
