SANTA MARIA, Brazil -- A 21-year-old man has been diagnosed with cutis verticis gyrata, a rare condition that forms folds and furrows in the scalp.
The unidentified man first began noticing the changes 2 years ago.
That's when his skin started to grow into thick, soft folds, resembling the ridges of the brain, according to a report in the New England Journal of Medicine.
The patient's hair was also affected.
It remained thick in the deep furrows of the skin, but thinned out over the large folds, said the authors of the study, Dr. Karen Schons and Dr. Andre Berber of the Hospital Universitario de Santa Maria in Brazil.
While the disorder has clearly affected the patient's appearance, doctors say it is largely a benign condition.
