Insights
A rare congenital skin condition presented as a large scalp mass and verrucous plaques in an infant. Clinical and pathological findings confirmed a new phenotype of polypoid nevus sebaceous.
Area of Science:
- Dermatology
- Pathology
- Pediatrics
Background:
- Nevus sebaceous (NS) is a congenital skin tumor typically presenting as a yellowish, waxy plaque.
- Large, polypoid variants of NS are rare and may exhibit diverse clinical presentations.
- Congenital skin anomalies require accurate diagnosis for appropriate management.
Abstract:
We present a 6-week-old female infant from the Lao People's Democratic Republic with a large, red, exophytic scalp mass and numerous flesh-colored verrucous plaques on her face and the right half of her body since birth. The clinical and pathological findings are consistent with the new phenotype of the large, polypoid types of nevus sebaceous.

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.
