Peripancreatic Lesions that Need to be Differentiated from Pancreatic Tumors

ABSTRACT

There are different kinds of peripancratic diseases that we can hardly differdntiate from pancreatic tumors preoperatively. Seventeen cases of peripancreatic lesions, in which preoperative diagnosis was made as pancreatic tumor during the last six year period were reviewed retrospectively. They were neurogenic tumor(4 cases), tuberculosis of peripancreatic lymph node(2 cases), recurred gastric cancer (2 cases), Castlemann's disease(2 cases), gallbladder cancer(1 case), splenic hematoma(1 case), mesenteric lymphangioma(1 case), lyphoepithelial tumor(1 case), omental cyst(1 case), pheochromocytoma(1 case) and teratoma(1 case). All of them were operated and confirmed histologically. In conclusion, for correct preoperative diagnosis and proper therapy, the application of additional diagnostic measures such as CT or ultrasound guided aspiration cytology, diagnostic laparoscopy, and endoscopic ultrasound should be considered when the diagnosis is not conclusive. The disease entities we mentioned in this paper should be excluded preoperatively or intraoperatively.
