Mesenteric fibromatosis (MF) is a rare tumor (2–4 cases per 1 million people annually) with few presented features. In this case study, we reported five MF patients, one of whom suffered a recurrence. Patients received renogram, colonoscopy, cystoscopy, and gastrointestinal examinations. Histology and immunohistochemistry evaluations were performed after the surgical resection. Hormone levels were measured before and after the surgery. It was found that clinical imaging readily confirmed an abnormal mass but was unable to distinguish MF from other tumors. Histology and immunohistochemistry were definitive diagnoses because the tissue was vimentin ± β–catenin ± CD117−/CD34−. Furthermore, the patient who suffered a recurrence showed an elevated estrogen level. A 6-month postoperative administration of letrozole drove the estrogen down to normal level. Our study showed that vimentin, β–catenin, CD117, and CD34 were the markers for MF whereas medical imaging, and estrogen level could be used for the complimentary purpose.
