A Case of Diffuse Neurofibroma of the Scalp Associated with Poliosis / 대한피부과학회지

ABSTRACT

A 37-year-old man presented with a 1-year history of asymptomatic ill-defined subcutaneous thickening with overlying whitish hairs on right occipital scalp. Histopathologic examination from this subcutaneous mass revealed neurofibromatous tissue with a diffuse infiltrative growth. S-100 protein staining showed decreased melanocytes and melanin in hair follicles. He was diagnosed as a diffuse neurofibroma associated with poliosis. To our knowledge, only two cases of poliosis associated with neurofibroma have ever been reported in English.
