Summary
Dermatofibrosarcoma protuberans (DFSP) is rare in infants but requires prompt diagnosis. Radical surgical excision is crucial for successful treatment and preventing recurrence, even after initial unplanned removal.
Area of Science:
- Oncology
- Dermatology
- Pediatric Surgery
Background:
- Dermatofibrosarcoma protuberans (DFSP) is a rare, locally aggressive soft tissue neoplasm originating in the dermis.
- While typically affecting adults, DFSP is exceptionally uncommon in infants, posing diagnostic and therapeutic challenges.
Observation:
- A case of infantile DFSP is presented, initially treated with unplanned excision.
- The infant presented with a superficial enlarging mass on the trunk.
Findings:
- Additional wide resection with a 3-cm margin was performed for the residual tumor.
- No recurrence of DFSP was observed for 3 years following the radical surgical intervention.
Implications:
- DFSP should be considered in the differential diagnosis of enlarging superficial masses in infants.
- Radical local treatment, including wide surgical margins, is essential for infantile DFSP, mirroring adult treatment protocols, even after prior incomplete excision.
