A Case of Diffuse Neurofibroma with Hair / 대한피부과학회지

ABSTRACT

Diffuse neurofibroma is an uncommon subtype of neurofibroma that occurs principally in children and young adults. It is most common in the head and neck region and appears clinically as a plaque-like elevation of the skin. A 3-year-old girl presented to our hospital with a complaint of skin-colored elevated plaques with hair on her lower back since birth. An ultrasonogram showed several 5~10 mm sized subcutaneous hypoechoic nodules with increased vascularity. The histopathologic examination revealed ill-defined, uncapsulated infiltrative, spindle shaped cells within the dermis and subcutaneous tissue. Immunohistochemical examination with antibodies to S-100 protein showed positive. We report a rare case of diffuse neurofibroma with hair.
