Plica neuropathica (PN) is an uncommon scalp condition that usually presents as a compact mass of scalp hair. We report a case of a 55-year-old woman presenting with PN. She presented with a 40-year history of thick plaques of yellow scale afflicting the entire scalp, progressive alopecia, and seeming lack of care of her own condition. Histology showed epidermal nevus-like features and severe miniaturization.
