Juvenile aponeurotic fibroma

Area of Science:

• Dermatology
• Orthopedic Oncology
• Pediatric Surgery

Background:

• Juvenile aponeurotic fibroma (JAF) is a rare, benign soft-tissue tumor typically affecting children and adolescents.
• While commonly found in the palms and fingers, JAFs can occur in other locations.
• Understanding the anatomical distribution of JAFs is crucial for diagnosis and treatment planning.

Observation:

• A case report details a large aponeurotic fibroma on the dorsum of the hand in a 14-year-old Nigerian male.
• This presentation is notable due to the tumor's size and specific location.
• The patient's demographic and geographic origin are also documented.

Findings:

• The reported case represents one of only two documented instances of juvenile aponeurotic fibroma occurring on the dorsum of the hand.
• Out of 43 reported cases of JAF of the hand in the literature, this dorsal location is exceptionally rare.
• This finding highlights the variability in the anatomical presentation of JAFs.

Implications:

• This case expands the known spectrum of JAF locations, particularly in pediatric populations.
• It underscores the importance of considering less common anatomical sites when diagnosing suspected soft-tissue tumors in children.
• Further documentation of rare presentations can refine understanding of JAF behavior and epidemiology.
