Obstructive jaundice due to a rare periampullary tumor

Table 1 Summary of case reports, findings and outcome from selected publications

Author	Presentation	Endoscopic findings	Outcome	Conclusion
Kwon et al[5]	56 yr old male with melena	EGD-tumor of ampulla of Vater with bleeding on surface	Pancreaticoduodenectomy	If followed up after a diagnosis, local excision can be curative, avoiding surgery or lymph node dissection
Okubo et al[6]	61 yr old male with epigastric pain and melena	EGD, ERCP, EUS-tumor of papilla of Vater	Pylorus-preserving Pancreaticoduodenectomy and lymph node dissection; Lymph nodes positive	Do not limit to local resection, as disease recurrence, lymph node involvement or distant metastases may occur
Witkiewicz et al[7]	38 yr old female with right upper quadrant abdominal pain	EGD-mass in duodenum near ampulla of Vater	Endoscopic excision of mass followed by pylorus-preserving pancreaticoduodenectomy as margin was positive	It may recur or metastasize; hence pancreaticoduodenectomy with lymph node dissection might be indicated for large lesions with infiltrative margin or lesions with pleomorphism and mitoses
Morita et al[8]	53 yr old male with incidental finding on EGD	EUS-submucosal tumor in the 3rd-4th layer	Endoscopic mucosal resection	Endoscopic removal is an alternative to surgical resection if no local or distant invasion
Sakhuja et al[9]	33 yr old male with obstructive jaundice	ERCP-periampullary growth	Pancreaticoduodenectomy	Recognize and diagnose this rare benign entity (with 3 components on H and E sections)
Evans et al[10]	56 yr old male with epigastric pain, vomiting and obstructive jaundice	EGD-pedunculated ampullary tumor	Pylorus-preserving total pancreatectomy	Benign entity-2 yr post procedure no recurrence of tumor

EGD: Esophagogastroduodenoscopy; ERCP: Endoscopic retrograde cholangiopancreaticography; EUS: Endoscopic ultrasound.
