In a recent, interesting article, Miller and Yeager1 report a sporadic case of hypertrichosis cubiti. In their article, they present the main features of the syndrome, based on this case and the 11 cases reported in the literature.
In 1992, we reported on two familial groups in which five patients presented with hairy elbows.2 The proband of family 1 was a 7-year-old boy who had had long, dark, coarse hair on both elbows since infancy. His father also had hairy elbows, but had observed a partial resolution of the hypertrichosis with age. Both patients were of short stature. No other abnormalities were present. The proband of family 2 was a 10-year-old girl who had diabetes mellitus. Her mother and aunt also had hairy elbows that showed partial resolution with age. Accordingly, hypertrichosis was noticeable only in the probands who were referred to us for other reasons, ie, psoriasis
