Abstract

A 70-year-old Caucasian man presented with a several-month history of a solitary, asymptomatic papule on the left eyebrow. His medical history included stage 1A lentigo maligna melanoma and multiple non-melanoma skin cancers. Physical examination demonstrated a solitary 5-mm smooth, dome-shaped skin colored papule with subtle central erosion on the left eyebrow. No overlying telangiectasias were noted. A biopsy of the lesion was performed. The lesion was composed of plump spindle cells arranged in a plexiform pattern in the background of thick, keloidal collagen bundles. The lesional cells were NKI/C3-positive and S-100-negative. A diagnosis of cellular neurothekeoma was made.
