Cutis verticis gyrata.

An 82-year-old man had deep, linear skin folds on the scalp. The patient did not have a history of neuropsychiatric disorders and was generally in good health except for diabetes mellitus, hypertension, and benign positional vertigo. Cutis verticis gyrata is a term used to describe the appearance of deep, linear skin folds in the scalp. Primary and secondary types of this condition exist. No treatment is typically needed, although surgical modalities may be beneficial for severely disfiguring types.
