title: [A case of rectal carcinoid tumor with lymph node and liver metastasis 5 years after curative resection].
abstract: A 65-year-old man was diagnosed with a rectal carcinoid tumor (10 mm in diameter) in July 2007. We performed low anterior resection with lymph node dissection. Histological depth of penetration of the rectal wall by the primary tumor was up to the submucosa, and lymph node metastasis was observed at station 251 (Japanese Classification of Colorectal Carcinoma, seventh Edition). Five years later, abdominal enhanced computed tomography (CT) revealed multiple liver tumors and swelling of the right obturator lymph nodes. During surgery, ultrasonography revealed 10 hypoechoic masses in both hepatic lobes. We performed right pelvic lymph node dissection, partial hepatectomy (S5/6, S7, and S8), and microwave coagulation therapy. After surgery, the patient was treated with octreotide long-acting repeatable( LAR). The patient remained disease-free for 10 months after surgery. Our findings suggest that careful monitoring is necessary for metachronous lymph node and liver metastasis during follow-up treatment for rectal carcinoid tumors.
