A Case of Small Rectal Carcinoid Tumor with Local Lymph Node Metastases / 대한소화기내시경학회지

ABSTRACT

Carcinoid tumors are rare and they arise from the enterochromaffin cells of the gastrointestinal tract. The rectum is the most common site for gastrointestinal carcinoids, and the majority of rectal carcinoids are found incidentally during colonoscopy. As the use of diagnostic colonoscopy has recently become more common, the number of cases with small rectal carcinoids resected by endoscopic resection has increased. However, distinguishing benign from malignant carcinoids is usually imposible based solely on the histology; therefore, evaluation for the local and distant metastases of rectal carcinoids is necessary even after complete endoscopic resection. We have experienced a case of small rectal carcinoid tumor that was endoscopically completely resected and surgical resection was done for the associated lymph node metastases.
