Abstract
We report the case of a 65-year-old woman presenting with a 15-month history of recurrent episodes of focal alopecia at the site of a bluish plaque on the vertex of her scalp. Histopathological examination revealed an admixture of focally nested oval, dendritic or epithelioid melanocytes together with slender spindle cells and occasional melanocytes. The spindle cells were positive for S100 and focally positive for epidermal membrane antigen, while the melanocytes were positive for S100 and Melan A.
