Trichoscopic Diagnosis and Management of a Case of Scalp Dysesthesia with Lichen Simplex Chronicus.

Scalp dysesthesia (SD), a variant of cutaneous dysesthesia syndrome is an underrecognized cause of scalp pruritus. It usually presents with itch, pain, burning, or stinging sensation over localized or diffuse area of the scalp without any objective findings. Trichoscopy, a rapid and in-office procedure, could aid in the early clinical diagnosis of this condition and initiate management. We report a case of SD in an elderly male diagnosed with the aid of trichoscope, evaluated and treated successfully.
