[Atypical presentation of infantile digital fibromatosis]

Area of Science:

• Dermatology
• Pediatric Oncology
• Pathology

Background:

• Infantile digital fibromatosis (IDF) is a rare, benign fibro/myofibroblastic tumor.
• Typically presents on the fingers and toes in infants and young children.
• Characterized by distinctive intracytoplasmic eosinophilic inclusions.

Observation:

• A case report of a 6-year-old child diagnosed with infantile digital fibromatosis.
• The tumor presented on the digits, consistent with typical IDF locations.
• Microscopic examination revealed characteristic bright, round, intracytoplasmic, eosinophilic inclusions.

Findings:

• The case aligns with the established clinical and histopathological features of infantile digital fibromatosis.
• Confirms the presence of characteristic eosinophilic inclusions in a pediatric patient.
• Demonstrates the typical presentation of this rare benign tumor.

Implications:

• Contributes to the literature on infantile digital fibromatosis, a rare pediatric condition.
• Highlights the importance of recognizing characteristic histopathological findings for accurate diagnosis.
• Underscores the benign nature and typical digital presentation of this fibro/myofibroblastic proliferation.
