A Rare Case of Secondary Cutis Verticis Gyrata on the Forehead

Abstract

Cutis verticis gyrata (CVG) is an unusual morphological condition of the scalp characterized by ridges and furrows resembling the surface of the brain. Most patients have lesions on the scalp, and only a few cases with forehead lesions have been described in literature. We report an extremely rare case of secondary CVG on the forehead. A 61-year-old female patient was referred to our outpatient clinic with a large area of hypertrophic skin on the forehead. A lesion measuring 12×3 cm extended across both eyebrows, the glabella, and the forehead. The patient reported that a pruritic erythematous lesion in that region had occurred 10 years ago after she performed acupuncture on herself on the forehead several times. She had no underlying diseases and no relevant family history. We removed the entire lesion and covered the defect with a forehead advancement flap. This solved the initial aesthetic problem. Her forehead skin became flattened, and the sagging upper eyelid skin was aesthetically corrected. Pathological findings showed nodular lesions with dense collagen fibers and microvascular proliferation, supporting the diagnosis of CVG. We achieved good results through surgical treatment for the extremely rare case of CVG on the forehead.
