Endoscopic ultrasound-guided fine needle aspiration biopsy of suspected cholangiocarcinoma  Mohamad A. Eloubeidi, Victor K. Chen, Nirag C. Jhala, Isam E. Eltoum, Darshana Jhala, David C. Chhieng, Sujath A. Syed, Selwyn M. Vickers, C. Mel Wilcox  Clinical Gastroenterology and Hepatology  Volume 2, Issue 3, Pages 209-213 (March 2004) DOI: 10.1016/S1542-3565(04)00005-9

Figure 1 EUS reveals a 22 × 15-mm echo-poor mass traversed by a stent (Olympus GF-UM-130). Clinical Gastroenterology and Hepatology 2004 2, 209-213DOI: (10.1016/S1542-3565(04)00005-9)

Figure 2 EUS reveals an echo-poor mass traversed by a stent (s). EUS-FNA (Olympus UC-30P) was performed next to the stent and revealed malignant-appearing cells compatible with cholangiocarcinoma. ne denotes needle.

Figure 3 Photomicrograph of Diff-Quik stained air-dried smear reveals characteristic features of carcinoma including loosely cohesive cell groups with nucleomegaly, marked variation in nuclear size, and dyscohesive single cells (Diff-Quik ×400). Clinical Gastroenterology and Hepatology 2004 2, 209-213DOI: (10.1016/S1542-3565(04)00005-9)

Figure 4 Photomicrograph of H&E-stained histologic section of the bile duct and surrounding parenchyma shows classical histological changes of cholangiocarcinoma: moderately to poorly differentiated carcinoma with extensive fibrosis (×200).
