Reconstruction of an Abdominal Hernia after Wide Tumor Resection with Multilayer Acellular Dermal Matrix and Skin Graft: A Case Report

Abstract

An abdominal hernia is a relatively common complication after abdominal surgery. However, no reports have previously described the reconstruction of a soft tissue defect with a hernia after wide excision of a tumor in the abdominal wall. A 41-year-old man presented with a painless, rapidly growing mass in his abdominal wall. Enhanced magnetic resonance imaging of the abdomen revealed a 7.8×6.4×4.2 cm mass, consistent with a soft tissue sarcoma suspected to be angiosarcoma in the subcutaneous layer of the left anterior upper abdominal wall. After wide excision of the mass, a hernia measuring 6.0×5.8 cm was observed. The abdominal hernia was repaired using multilayered acellular dermal matrix (ADM), and the soft tissue defect was covered with a split-thickness skin graft. A histopathological examination confirmed that the mass was fibrosarcomatous dermatofibrosarcoma protuberans (DFSP-FS). No complications occurred after surgery, and the patient was followed up for 10 months without any issues. Herein, we present a case of hernia after the removal of DFSP-FS in the abdominal wall, which was repaired using multilayer ADM and a split-thickness skin graft.
