Treatment of a Desmoid Tumor That Enlarged During Pregnancy: A Case Report and Literature Review

Summary

Desmoid tumors are rare soft-tissue tumors that exhibit locoregional aggressiveness and a high local recurrence rate following initial resection. No fixed recommendations have been established with regard to the timing and method of treatment for desmoid tumors that enlarge during pregnancy. Desmoid tumors tend to enlarge during pregnancy, and most do not regress spontaneously postpartum. Thus, surgery may be required even during pregnancy. We report a case of an abdominal wall desmoid tumor that grew to 90 mm during pregnancy and was resected at 17 weeks of gestation. Marginal resection was performed, and the surgical margin was microscopically positive. The postoperative course and the pregnancy were uneventful, and no recurrence was observed at the 15-month follow-up visit.
