[Solid, asymptomatic nodules on several toes in a child].

Area of Science:

• Dermatology
• Pediatric Oncology
• Pathology

Background:

• Infantile digital fibromatosis (IDF) is a rare benign tumor, accounting for approximately 2.5% of all fibromatoses.
• The exact cause (etiopathogenesis) of IDF remains unknown.
• These tumors typically present as asymptomatic, solid nodules on digits within the first three years of life.

Observation:

• IDF nodules are often pink or skin-colored and can be present at birth or develop shortly after.
• They commonly affect one or multiple fingers or toes.
• The tumors are generally asymptomatic.

Findings:

• Surgical excision of IDF is associated with a high postoperative recurrence rate, ranging from 50% to 75%.
• A significant proportion of IDF cases exhibit spontaneous regression, indicating a self-limiting nature.
• Current evidence does not support surgical intervention as the primary treatment modality.

Implications:

• The high recurrence rate and possibility of spontaneous resolution suggest conservative management for infantile digital fibromatosis.
• Further research into the etiopathogenesis of IDF may reveal less invasive treatment strategies.
• Pediatricians and dermatologists should be aware of the natural history of IDF to guide appropriate clinical decision-making.
