Pigmented Neurofibroma of the Skin

Pigmented neurofibroma is a rare variant of neurofibroma commonly associated with neurofibromatosis 1 of diffuse type. Histopathologic examination is essential to differentiate it from other pigmented lesions. We report here a case of pigmented neurofibroma of skin, which was diagnosed after histopathology, histochemistry and immunohistochemistry. We also review the pertinent literature to highlight the differential diagnoses.
