Desmoid tumors are rare; however, they sometimes form in the abdominal wall after surgery or trauma. We report a case of desmoid tumors in the abdominal wall mimicking port-site metastasis after laparoscopic surgery for endometrial cancer. A 53-year-old woman with familial adenomatous polyposis presented to our hospital with vaginal bleeding and was diagnosed with endometrial cancer. We performed a total laparoscopic hysterectomy and began observation. Two years after surgery, follow-up computed tomography revealed three nodules with a size of approximately 15 mm in the abdominal wall at the trocar sites. Tumorectomy was performed because endometrial cancer recurrence was suspected, but desmoid fibromatosis was finally diagnosed. This is the first report of desmoid tumors at the trocar site after laparoscopic surgery for uterine endometrial cancer. Gynecologists should be aware of this disease because differentiating it from metastatic recurrence is challenging.
