Double-layer biodegradable temporising matrix reconstruction for abdominal skin and soft-tissue reconstruction.

Dermatofibrosarcoma protuberans (DFSP) is a rare, locally invasive dermal sarcoma. The management is generally surgical, with wide local excision (WLE) forming the mainstay of treatment. Large abdominal wall defects are most aesthetically reconstructed using pedicled or free flaps; however, these require tumour-free surgical margins, and are off-set by donor site morbidity. We describe an alternative, aesthetic and low-morbidity technique for reconstruction of a subfascial defect following WLE of DFSP in a young woman in her early 20s, using two layers of a novel synthetic dermal matrix (NovoSorbBTM). To our knowledge, a double-layer reconstruction using an artificial dermal matrix has never been described for trunk reconstruction. We found that double-layer biodegradable temporising matrix can restore the inherent thickness and pliability of skin in a partial-thickness abdominal wall defect and offers improved durability and cosmesis compared with skin grafting or indeed single layer skin substitutes alone.
