Abstract

We report a case of nevus spilus with necrotized nevus studied by immunohistochemical methods using S-100, leu-7, glial fibrillary acid protein (GFAP), and myelin basic protein (MBP). Histologic findings of the speckled lesion showed irregular fete ridge elongation, increased epidermal melanocytes and melanin in the epidermis, and scattered nevus cell nests in the upper dermis, but showed necrotized nevus in the deep dermis, which has many features of neurofibroma. Diffuse expression of S-100 protein and MBP, focal staining with GFAP, and lack of staining with leu-7 were observed, Leu- 7, positive only in neurofibromas and not in necrotized nevus, appears to be the more pertinent method for distinguishing necrotized nevus from neurofibroma.
