Rectal carcinoid tumor, 6 mm in diameter, with lymph node metastases.


hospital because of a positive fecal occult blood test. Colonoscopy revealed a hemi− spheric submucosal tumor, 8 mm in di− ameter, at the lower rectum (l" Fig. 1a). There was neither a central depression nor ulceration on the lesion. The patho− logical diagnosis of the biopsy specimen was carcinoid tumor. Abdominal CT de− tected no liver or lymph node metastasis. The lesion was diagnosed as a rectal carci− noid tumor confined to the submucosal layer, and therefore endoscopic submuco− sal resection with a ligating device (ESMR−L) [1] was performed. The pathological diagnosis of the endo− scopically resected specimen was a rectal carcinoid tumor, 6 mm in diameter, in− vading the submucosa by 2900 m from the surface (l" Fig. 1b). The surgical mar− gin was negative. However, lymphatic permeation was confirmed by D2 ± 40 im− munohistochemistry (l" Fig. 1c), and the Ki−67 labeling index (l" Fig. 1d) was in− creased to 1.66. Therefore, the patient un− derwent low anterior resection of the rec− tum. There was no residual tumor in the rectal wall, but two out of seven regional lymph nodes revealed metastasis of the carcinoid (l" Fig. 2).
