Abstract:
Pigmented neurofibroma is a rare cutaneous tumor accounting for less than 1% of all neurofibroma. It is characterized histologically by the coexistence of scattered melanin-laden cells and benign spindle cells with neural differentiation. The origin of these tumors are unknown, and they show a storifom pattern. In our case, the patient had giant cafe au lait patches on the left trunk which had been present since birth, freckles on both axilla, and two dark-red colored plaques which had appeared 2 years ago. Histologic examination revealed pigmented neurofibromas showing the melanin-laden, pigmented cells within the upper dermis and plexiform neurofibromas in the subcutaneous tissue. We describe a case of pigmented neurofbroma in a 13-year-old male patient.
