Fleur-de-lis Miniabdominoplasty Access in Radical Resection of a Large Abdominal Wall Desmoid Tumor

Abstract

Summary: Desmoid tumor (DT) is a rare benign soft tissue neoplasm that develops in the musculoaponeurotic structures, one-third of which involve the abdominal wall. Due to local aggressive infiltration of DT, the recurrence rate is approximately 45%–77%, according to the locations of the tumors, and 25%–50% for those with unclear surgical margins. Limited by adverse effects of radiotherapy and chemotherapy, surgical excision is still the standard management recommended. Differing from traditional midline or abdominoplasty access, we applied a fleur-de-lis miniabdominoplasty access in a 37-year-old woman who had primary abdominal wall DT with less than 1 cm depth from the umbilicus. The approach not only provides a better surgical field for radical tumor excision but also eliminates redundant skin and dog-ear formation at bilateral flanks. An appropriate surgical margin could be processed simultaneously when the tumor was close to the skin surface. After abdominal wall reconstruction, the postoperative course was uneventful, and no DT recurrence or incisional hernia was noted during the follow-up. The patient was satisfied with the tumor treatment and aesthetic outcome.
