Recurrent metastatic Klatskin's carcinoid tumor to celiac lymph nodes in a teenager: diagnosis by endoscopic ultrasound-guided fine needle aspiration biopsy with immunocytochemical correlation.

Abstract

Tumors of the extrahepatic ducts are relatively rare and consist mostly of adenocarcinomas. Carcinoid tumors of the bile duct are exceedingly rare (1–4). Only 26 cases of carcinoid tumors of the bile duct are reported in the literature (5); 3 of these occurred in childhood or adolescence (1,6,7). Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) biopsy is an effective method for tissue diagnosis of periintestinal lymphadenopathy, especially in the posterior mediastinum and the celiac axis area (8). We report this case to illustrate the role of EUS-FNA in diagnosing recurrent metastatic carcinoid Klatskin’s tumor to a celiac lymph node in a teenager.
