[Hereditary sclerodactyly and syndactyly].

A 61-year-old man is described with sclerodactyly of the hands and syndactyly of the second and third toes. Hereditary sclerodactyly is a rare condition, beginning in early youth with flexion contracture of the fingers. In this patient the skin of the fingers was sclerotic and thickened, and the dorsal skin of the hands was atrophic and dry. The condition did not progress nor did it show signs of Raynaud's phenomenon. Both feet showed syndactyly of the second and third toes. The family tree suggested autosomal dominant inheritance, with reduced penetrance since the grandfather of our patient was reported to have had a similar disease.
