Type of disease: Rare conditions
Pachydermoperiostosis is a rare disorder characterized by clubbing of the fingers and toes; thickening of the skin of the face (pachyderma); excessive sweating (hyperhidrosis); and new bone formation associated with joint pain. Other features may include congenital heart disease and delayed closure of fontanelles. This condition typically appears during childhood or adolescence, often around the time of puberty, and progresses slowly for about ten years. Both autosomal dominant and autosomal recessive inheritance has been reported. Mutations in the HPGD gene have been found in those with the autosomal recessive form of this condition.
