Gómez-López-Hernández Syndrome: A Rare Cause of Bilateral Nonscarring Alopecia.

Gómez-López-Hernández syndrome is a rare neurocutaneous disorder characterized by the triad of rhombencephalosynapsis, parietal alopecia, and trigeminal anesthesia. We report a 16-year-old girl with bilateral parietotemporal alopecia in whom cranial magnetic resonance imaging revealed rhombencephalosynapsis, suggesting a diagnosis of Gómez-López-Hernández syndrome. Neurologic examination and neuroimaging may be warranted in select patients with parietal alopecia to exclude this uncommon entity.
