Asynchronous Liver Metastasis from Rectal Carcinoid Tumor 12mm in Diameter: A case report A 53-year-old man was diagnosed with a rectal carcinoid tumor at Rs because of fecal occult blood.
We performed transsacral resection of the rectal tumor. The rectal carcinoid measured 12×10mm and tumor invasion was limited to the submucosal layer. About 3 years later, we diagnosed liver metastasis from the rectal carcinoid tumor, and performed lateral segment rescection of the liver. The liver tumor measured 35×30mm, the histological finding of the tumor was rectal carcinoid-like tumor. In the Japanese literature, only 6 cases of liver metastasis from rectal carcinoid tumor, smaller than 20mm and limited to the submucosal layer have been reported. To our Knowledge, this is the first case to be reported in Japan of liver metastasis after resection of rectal carcinoid tumor.
