Recurrent abdominal wall dermatofibrosarcoma protuberans in a child: a challenging reconstruction.

INTRODUCTION

Dermatofibrosarcoma protuberans is an uncommon low-grade soft tissue sarcoma with a high potential for recurrence as it has irregular finger like extensions.

CASE DESCRIPTION

We report a case of a large, recurrent dermatofibrosarcoma protuberans in a child involving the anterior abdominal wall, which posed a challenge for reconstruction. Peritoneum sparing full thickness resection of the anterior abdominal wall, meshplasty and a free anterolateral thigh flap was performed for reconstruction of the defect.

DISCUSSION AND EVALUATION

Large composite defect, involving more than half of the anterior abdominal wall, necessitate a free flap reconstruction. Although these reconstructions are technically challenging in children, they are the only option available.

CONCLUSION

Complete surgical excision is essential for DFSP of the abdominal wall, which may result in large challenging defects. Free flaps remain the only option in this scenario and hence it is essential to have expertise for microvascular flap reconstruction.
