Hypertrichosis Cubiti: Another Case of a Well‐Recognized but Under‐Reported Entity

Abstract: Hypertrichosis cubiti, also named hairy elbows syndrome, is an uncommon variety of congenital, circumscribed hypertrichosis with a remarkable amount of long vellous hair localized on the extensor surfaces of the upper extremities. It may appear both as a familial or sporadic form. In most patients, it is not associated with any other physical anomalies, although short stature and other development disorders have been described. We report a case occurring sporadically in a 5‐year‐old girl without associated abnormalities, and with a negative family history.
