HYPERTRICHOSIS CUBITI - DISAPPEARANCE OF AN HEREDITARY TRAIT WITH AGE

Hypertrichosis cubiti (hairy elbows) is a localized form of increased hairiness involving the third distal of the upper arm and the proximal third of the forearm, bilaterally. The authors report this trait in a 7-year-old girl and in her father, who had experienced a disappearanc e of the increased hairiness with age. There was also hypertrichosis o f the knees. This observation confirms that hypertrichosis cubiti is a n hereditary trait showing a probably autosomal dominant mode of trans mission and resolving spontaneously with age.
