| [ Summary ] |
Pertinent findings from endoscopy and radiography of rectal carcinoids generally include yellowish submucosal tumors with smooth surfaces, since the size is less than 10mm. With increases in tumor size, central depressions are more often observed, along with ulcerations or reddish discoloration. Endoscopic ultrasonography reveals that carcinoid tumors are clearly of submucosal origin, with homogeneous hypoechos.
Carcinoid tumors may possiblely metastasize when tumors are over 20mm in size. However, we must note that even the smaller tumors under 20mm, may metastases when associated with central depressions and/or ulceration. |
