Objective:
To report on a rare case of Pacinian neurofibroma of the vulva.
Methods:
A 27-year-old patient who presented with a vulvar tumor is described. Patient evaluation showed no other remarkable findings.
Results:
The nodule was resected without difficulty. The histopathological analysis-demonstrated Pacinian neurofibroma with abundant concentric laminar structures. The immunohistochemical (CD34+), ultrastructural and histological analyses showed perineural cells. No signs of neurofibromatosis were found.
Conclusions:
Pacinian neurofibroma may present in the vulva and could probably arise from the so-called perineural fibroblasts.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
