Isolated cutis verticis gyrata of the glabella and nasal bridge: a case report and review of the literature.

Cutis verticis gyrata (CVG) is an uncommon morphological condition of the scalp characterised by ridges and furrows resembling the surface of the brain. We present a case of secondary CVG affecting both the glabella and nasal aesthetic unit. To our knowledge, isolated CVG of the glabella has never been reported nor has extension of CVG onto the nasal aesthetic unit of the face. We also describe an association between hyper-IgE syndrome and CVG, and review this rare disorder including options for its surgical management.
