White fibrous papulosis of the neck
Abstract:
We report a case of white fibrous papulosis of the neck in a 70-year-old Iranian woman. To date this recently reported entity has only been described in Japanese patients. This asymptomatic eruption characteristically affects the posterior neck. The pale papules are round to oval 2-3 mm in diameter, and not follicular. Histology shows thickened collagen bundles in the superficial and mid-dermis with a normal elastic pattern.

Introduction to 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.
