Lymphatic malformations are benign tumors that arise from congenital defects of the lymphatic system. Despite the fact that all lymphatic malformations develop embryologically, their presence may not be detected until the tumor enlarges from hemorrhage or infection. Typical of these tumors is a slow-growing, asymptomatic phase with the potential for rapid and massive expansion and a tendency to infiltrate into surrounding tissues. These tumors are associated with a high rate of recurrence, especially with incomplete excisions. To minimize the chance of recurrence, a complete resection of a groin microcystic lymphatic malformation was performed on this 15-month-old boy, creating a significant defect in the upper thigh. Immediate coverage was felt to be the best option for reducing any associated morbidity. We used a skin-soft tissue flap supplied by perforators of the deep inferior epigastric artery to repair the wound. Using this technique, the musculofascial structures in the abdominal wall were completely spared, and the skin and fat were transferred on a vascular leash to the desired location. The donor site was closed by approximating the fascial edges without tension. The defect on the thigh was filled with tissue of similar thickness and characteristics, avoiding potential contour irregularities and color mismatch. The deep inferior epigastric perforator (DIEP) flap is a useful option for groin defects and can be applied safely in the pediatric population.
