Abstract:
Pilomatrixoma is a benign adnexal tumour characterised by pathological hair matrix differentiation and is most commonly observed in children. It typically presents as a slow-growing, pink to purplish dermal nodule. Due to its low clinical diagnostic accuracy, pilomatrixoma is often misidentified as other tumours. This case highlights an atypical presentation of pilomatrixoma in a girl in early adolescence and underlines the importance of considering ultrasonography or proceeding directly to surgical excision for definitive diagnosis.

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.
