Congenital Atrophic Plaque: Fibroblastic Connective Tissue Nevus

Area of Science:

• Dermatology
• Pediatric Pathology
• Medical Genetics

Background:

• Fibroblastic connective tissue nevus (FCTN) is an uncommon benign dermal tumor.
• FCTN primarily affects the pediatric population, presenting as a mesenchymal hamartoma.
• Understanding FCTN's diverse presentations is crucial for accurate diagnosis.

Observation:

• A 15-year-old male presented with a congenital FCTN.
• The case involved detailed clinical examination and dermatoscopic evaluation.
• Histopathological analysis provided definitive diagnostic features.

Findings:

• The report elucidates the specific clinical manifestations of congenital FCTN.
• Dermatoscopic findings offer unique insights into the tumor's superficial characteristics.
• Histopathology confirmed the diagnosis, detailing the fibroblastic and connective tissue components.

Implications:

• This case contributes to the limited literature on FCTN, particularly congenital forms.
• Enhanced understanding of FCTN's features aids in differentiating it from other pediatric skin lesions.
• Accurate diagnosis of FCTN is essential for appropriate patient management and prognosis.
