Background:
Wound defects after wide local excision (WLE) for cutaneous melanoma can occasionally require the use of skin grafts for closure. Harvesting the skin graft can result in an additional wound.
Methods:
The increasing use of sentinel lymph node (SLN) biopsy in cutaneous melanoma at our institution has facilitated the development of an alternative technique for obtaining donor skin. The proposed method utilizes the skin overlying the SLN as the skin graft donor site. Sixteen patients underwent WLE of intermediate to thick melanomas with SLN biopsy and full thickness skin graft harvested from the SLN biopsy site.
Results:
After a median follow-up of 12 months, there were no graft failures. There were 2 partial graft losses. There were no wound complications. There were no melanoma recurrences.
Conclusions:
In cases where primary closure is not technically feasible or cosmetically favorable, the use of the SLN incision site as a skin graft donor provides the surgeon with an effective repair and spares the patient an additional skin graft donor site defect.
