[Benign skin neoplasms in children]

Area of Science:

• Pediatric Dermatology
• Dermatopathology

Background:

• Most pediatric skin neoplasms are benign, requiring accurate differentiation by dermatologists.
• Surgical excision is a primary treatment modality for benign skin neoplasms.

Purpose of the Study:

• To provide a comprehensive overview of various benign skin neoplasms in children.
• To discuss diagnostic and therapeutic considerations for pediatric skin tumors.

Main Methods:

• Literature review of epidermal lesions, appendage tumors, fibromatoses, and fibrotic reactions.
• Discussion of histopathological and genetic studies in understanding pathogenetic mechanisms.

Main Results:

• Categorization of pediatric skin neoplasms including epidermal lesions (e.g., inflammatory linear verrucous epidermal nevus, nevus sebaceous), appendage tumors (e.g., pilomatrixoma), cutaneous neoplasms (e.g., angiofibroma), fibromatoses (e.g., knuckle pads), tumors of fat, muscle, or bone (e.g., osteoma cutis, subungual exostosis), epidermal cysts, and keloids.
• Emphasis on the limited availability of scientific data and recent progress in histopathological and genetic research.

Conclusions:

• Accurate diagnosis of pediatric skin neoplasms is crucial for appropriate management.
• Advancements in molecular techniques are improving the understanding of the pathogenesis of these lesions.
