Endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) is a useful modality when the target is a lymph node located in the mediastinum, perigastric area or perirectum. Although it is difficult to carry out EUS‐FNA of the colon using an oblique view linear scope, we report two cases of successful EUS‐FNA of the lesions via the proximal sigmoid colon using a recently available new convex type EUS scope. Case 1 was a 77‐year‐old Japanese woman noted to have multiple lymph node swelling in the para‐aortic area and in the pelvis. Case 2 was a 60‐year‐old Japanese woman noted to have a large mass in the left lower abdomen. In case 1, oral EUS showed no lymph node swelling. In both cases, EUS with forward‐viewing radial echoendoscope was carried out via the anus, and multiple lymph‐node swelling or a large mass was observed near the proximal sigmoid colon. In the EUS‐FNA for these cases, we used a new convex‐type EUS scope that has an oblique view, but with a wide‐angled optical device giving a view similar to a forward one. EUS‐FNA was successfully carried out on the lesions. The pathological specimen revealed diffuse large B‐cell lymphoma in case 1 and gastrointestinal stromal tumor (GIST) in case 2.
