Dermatological marks in athletes of artistic and rhythmic gymnastics.

The authors present dermatological signs in: a) rhythmic gymnastics athletes, b) male artistic gymnastics athletes, compared to a control group of fitness athletes. Athletes from the artistic gymnastics group were observed twice. The signs they showed on their first examination (20 days previous to the competition) were two circular zones of thickening of the skin with relation to the radial epiphysis. In all of them, two zones of frictional alopecia were present, one on the dorsal face of the forearms, slantwise outlined, the other on the wrists. A noticeable thickening of the skin was present on the palms of the hands. On a second examination, at the beginning of the training, after about two months of inactivity, the alopecic area was replaced by hypertrichosis, although featuring different patterns in each athlete. Thickening of the skin was slightly smaller than that observed at the first examination. The authors describe onychopathology shown in its different forms in 94% of the athletes of the rhythmic group. Subsequently the authors discuss the pathogenesis of the above described signs.
