Cutis verticis gyrata as a clinical manifestation of Touraine-Solente-Gole' syndrome (pachydermoperiostosis).

Cutis verticis gyrata is a descriptive term for a condition of the scalp consisting of deep grooves and convolutions that resemble the surface of the brain. We present a case of a 22-year-old man who presented with pain and swelling of both knees and hands. Enlarged wrists, ankles and feet were also noted, along with facial seborrhoea, thickening of the skin and deformity of the fingers. Physical examination of the scalp showed a cerebriform appearance with accentuating folds and deep furrows (cutis verticis gyrata), thickening in the face, frontal and parietal regions. Bone enlargement of the hands, knees, ankles and feet was also found. Secondary causes of pachydermoperiostosis were negative.
