Abstract:
Follicular porokeratosis represents a rare variant of porokeratosis, distinguished histologically by the presence of cornoid lamella confined to the follicular infundibulum. We report a case of alopecia secondary to follicular porokeratosis confined to the scalp, which has been rarely reported in the literature. This report aims to raise awareness of follicular porokeratosis as a potential cause of alopecia, and to prompt pathologists to examine the epidermis for porokeratosis in biopsies for alopecia in which a cause is not identifiable otherwise.

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.
