Whole-exome sequencing uncovers frequent GNAS mutations in intraductal papillary mucinous neoplasms of the pancreas
Intraductal papillary mucinous neoplasm (IPMN) is a common pancreatic cystic neoplasm that is often invasive and metastatic, resulting in a poor prognosis. Few molecular alterations unique to IPMN are known. We performed whole-exome sequencing for a primary IPMN tissue, which uncovered somatic mutations in KCNF1, DYNC1H1, PGCP, STAB1, PTPRM, PRPF8, RNASE3, SPHKAP, MLXIPL, VPS13C, PRCC, GNAS, KR...
متن کاملAppendiceal mucinous neoplasms: controversial issues.
Low grade appendiceal mucinous neoplasms can spread to the peritoneum as pseudomyxoma peritonei even though they are not obviously invasive in the appendix. During the past several decades, several problematic issues surrounding this enigmatic tumor have been debated in the literature, including appropriate nomenclature for the appendiceal tumors and their peritoneal metastases. In this article...
متن کاملLow-grade appendiceal mucinous neoplasm and endometriosis of the appendix
BACKGROUND A distended, mucous-filled appendix is known as an appendiceal mucocele. They are a rare form of an appendiceal mass and develop from both benign and malignant processes. Mucoceles can develop secondarily to an obstruction, such as from a fecalith, scarring or, rarely, endometriosis. Only 12 cases of non-neoplastic appendiceal mucoceles caused by endometriosis have been previously de...
متن کاملLow-Grade Appendiceal Mucinous Neoplasm Presenting as an Adnexal Mass
Appendiceal tumors are rare, late diagnosed neoplasms that may not be differentiated from adnexal masses even by advanced imaging methods and other diagnostic procedures. They may be asymptomatic and remain undiagnosed until surgery. We report a case of an 80-year-old postmenopausal woman presenting with a pelvic mass and a history of weight loss. The patient underwent laparotomy which revealed...
متن کاملAn incidental discovery of low-grade appendiceal mucinous neoplasm.
A 65-year-old man with a history of hyperplastic polyps underwent a surveillance colonoscopy, which revealed a large, smooth cystic bulge at the appendicular orifice (Figure 1). Subsequently, a computed tomography (CT) of the abdomen with contrast revealed an appendiceal mucocele measuring 13.3 x 4.5 cm (Figures 2a and 2b). Because of the abnormal imaging findings, an elective laparoscopic appe...
