Desmoid tumor arising in a cesarean section scar during pregnancy: Monitoring and management

Desmoid tumors (DTs) are frequently associated with either surgical trauma, like scars, or physiologic trauma, like pregnancy. A DT arising in a cesar ean scar during pregnancy shows both correlations. A case of DT that grew g radually in a cesarean scar during the first trimester of a subsequent preg nancy is presented. After initial MR imaging, the lesion was biopsied and c arefully monitored; immediate surgical removal was considered at any time i f indicated by the follow-up results. No increase in the tumor size was obs erved during the following 6 months of gestation, and the lesion was extirp ated with mesh replacement of the abdominal defect at the time of cesarean section.
