ABSTRACT

Carcinoid tumors are a very rare type of slow-growing cancer that arises in 0.5 to 8.4/100,000. The most common place of presentation is the gastrointestinal tract (68%) followed by the lungs and bronchus (25%). Rectal carcinoids represent 1.8% of the malignant neoplasms in the rectum being more frequently found during the sixth decade of life. Approximately 50% of the patients are asymptomatic at the moment of presentation, and most of them are diagnosed incidentally with a routine colonoscopy. Case report: A 61 year-old-male with an ongoing history of hematochezia for twelve months was seen in our service. A rectal lesion of 2 cm of diameter, at 8 cm of the anal margin was found. I biopsy was performed reaching the diagnosis, of poorly differentiated adenocarcinoma. Hepatic metastatic lesions were observed in the staging process. Treatment with chemotherapy was begun without improvement. A review of the histopathological report by another doctor was requested reaching the diagnosis of a neuroendocrine tumor. A Positron emission tomography computed tomography was performed, finding metabolic evidence in the rectum and the hepatic lesions. A hand assisted laparoscopic resection of the tumors was fulfilled with metastasic hepatic resection.
