Case Of Serous Cystic Neoplasm Research Articles

A case of serous cystic neoplasm with tumor growth acceleration leading to extrapancreatic invasion.

Serous cystic neoplasm (SCN) is a potentially malignant and invasive disease. However, there are no established guidelines regarding the surgical management of SCN. Here, we report a case of SCN with jejunal invasion that ultimately required a distal pancreatectomy with partial resection of the jejunum. The patient was a 65-year-old female who was referred to our department after a diagnosis of SCN in the pancreatic tail. CT and MRI showed a 75-mm multifocal cystic mass with calcifications; the splenic vein and left adrenal vein were entrapped within the tumor. Furthermore, the tumor was in contact with the beginning of the jejunum. Finally, she underwent a posterior radical antegrade modular pancreatosplenectomy with a partial wedge-shaped resection of the jejunum. Histological findings indicated serous cystadenoma. In addition, the tumor cells were found to have infiltrated the jejunal muscularis propria in some areas, suggesting that the tumor had malignant potential. Currently, 14months have passed since surgery and there is no evidence of metastasis or recurrence. Surveillance and the decision to perform surgical resection should be made based on tumor size and growth rate to avoid malignant transformation as well as to provide SCN patients with organ-sparing, less invasive surgery.

A long-term survivor of metachronous liver metastases of pancreatic serous cystic neoplasm associated with von Hippel\u2013Lindau disease

BackgroundPancreatic serous cystic neoplasm (SCN) is an uncommon exocrine neoplasm, which is believed to be a benign entity. However, some of these neoplasms may occasionally attain metastatic ability. Von Hippel–Lindau disease (VHL) manifests a dominantly inherited systemic syndrome accompanied by several benign or malignant tumors, including cystic tumors, in various organs. We describe here a long-term survival case who underwent surgical resection for metachronous liver metastases of pancreatic SCN associated with VHL disease.Case presentationA 35-year-old woman with VHL underwent total pancreatectomy and right nephrectomy for pancreatic SCN and renal cell carcinoma, respectively. At the 4th year follow-up examination after the resection, contrast-enhanced computed tomography (CT) and gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) showed arterially hyper-enhanced neoplastic lesions in the segment VI and VIII of the liver. Partial resections of the liver were performed 53 months after the initial surgery. At the 6th month follow-up examination from the second surgery, one and two tumors located in the liver segment III, and VIII, respectively, were detected by contrast-enhanced CT and Gd-EOB-DTPA-enhanced MRI. Anterior segmentectomy and partial resection of the segment III were performed 66 months after the initial surgery and 13 months after the second, respectively. The tumors were pathologically diagnosed as liver metastases of pancreatic SCN synonymous with serous cystadenocarcinoma. She remains disease-free without recurrence 6.5 years after the last operation.ConclusionsThis is the first report of a case of metastatic SCN associated with VHL. Surgical resection might confer a favorable prognosis in patients of pancreatic SCN with liver metastases.

A Serous Cystic Neoplasm of the Pancreas with Synchronous Pancreatic Ductal Adenocarcinoma

Serous cystic neoplasm (SCN) represents 10–16% of cystic pancreatic lesions, first classified by Compagno and Oertel at 1978. In contrast to mucinous cystic neoplasm or intraductal papillary mucinous neoplasm of pancreas which have malignant potential, SCN is thought to be exclusively benign as solitary lesion in nearly all cases. There has been rare reported association between the SCN and pancreatic ductal adenocarcinoma, and few cases were documented their coexistence. In this report, we present the case of SCN of the pancreas with literature review in which synchronous pancreatic ductal adenocarcinoma and pancreatic intraepithelial neoplasm coexist together.

A case of serous cystic neoplasm of the pancreas with stenosis of the main pancreatic duct

A 64-year-old woman was accidentally detected to have multiple cystic tumors measuring 30 mm in diameter in the pancreatic head in 2009. The probable diagnosis was a serous cystic neoplasm of the pancreas. However, the tumor had grown to 52 mm in diameter in 4 years, and endoscopic retrograde pancreatography (ERCP) showed stenosis of the main pancreatic duct. We performed subtotal stomach-preserving pancreaticoduodenectomy, and histopathological diagnosis was serous cystadenoma.

Serous cystic neoplasm in an intrapancreatic accessory spleen

Serous cystic neoplasm (SCN) of the pancreas is a benign epithelial neoplasm, except in extremely rare malignant cases. Development of SCN in tissues other than the pancreas has been never reported. Here we present the first reported case of SCN in an intrapancreatic accessory spleen (IPAS). A 54-year-old female patient with von Hippel-Lindau (VHL) syndrome was found to have pancreatic tail mass. Pathologically the 25-mm solid mass was an IPAS showing proliferation of clear cuboidal tumor cells without atypia, forming numerous small cysts. The tumor cells were rich in cytoplasmic glycogen and distributed in the splenic tissue almost diffusely. Immunohistochemically, tumor cells were positive for cytokeratins, MUC6, and neuron-specific enolase, and negative for neuroendocrine markers. From these findings, we diagnosed the lesion as SCN in IPAS. This tumor is suggested to develop as a VHL-associated SCN from coexisting pancreatic tissue in IPAS rather than as a metastatic tumor.

A Case of Serous cystic neoplasm (SCN) with back pain

症例は55歳，女性。背部痛，体重減少を主訴に来院。腹部エコーでは膵尾部に嚢胞性病変が疑われ，精査となった。画像検査上，SCNが最も疑われたが，MCN（mucinous cystic neoplasm）との鑑別が難しく，informed consentの上，手術を行い，診断を確定した。今回，MCNとの鑑別に難渋したSCNの1例を経験したので報告する。
