Abstract

Gastrointestinal stromal tumors (GISTs) arising from the rectum are rare. We report the case of an aggressive rectal gastrointestinal stromal tumor (GIST) in a 60-year-old female that presented for symptoms of constipation and lower gastrointestinal bleeding. Upon rectal examination, a hard mass was found at 6cm from the anal marge. An MRI was indicated that shows a well-demarcated lesion originates from the distal rectum with exophytic growth and central necrosis. The diagnosis of rectal gist was confirmed by colonoscopy with biopsy and immunohistochemical analyses of bioptic material. Liver metastases were seen on computerized tomography (CT). She was referred for palliative chemotherapy. The patient had suffered from intestinal obstruction three weeks after his initial presentation and passed away shortly thereafter. We aimed to report this case as an aggressive and rare GIST localization.
