Pancreatic splenosis mimicking neuroendocrine tumors: microhistological diagnosis by endoscopic ultrasound guided fine needle aspiration.

Context: Pancreatic splenosis is a benign condition which can mimic a pancreatic neoplasm.

Objective: To describe the role of the endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of pancreatic nodules suspicious for pancreatic splenosis.

Method: From 1997 to 2011, patients with pancreatic solid tumors suspicious for splenosis by computed tomography and/or magnetic resonance imaging were referred to EUS-FNA.

Upper endoscopy versus endosonography in differential diagnosis of gastrointestinal bulging.

Context: The identification of a bulging covered by normal epithelium is a common finding during an upper gastrointestinal endoscopy.

Objective: To compare the endoscopic and endosonography findings in the differential diagnosis of the gastrointestinal bulging (subepithelial tumor or extrinsic compression).

Method: Patients referred by endosonography with bulging of upper gastrointestinal tract were studied retrospectively.
