胰腺实性假乳头状肿瘤

胰腺实性假乳头状瘤（SPTP）是一种罕见的低度恶性胰腺肿瘤,其组织来源尚不清楚。近年来,随着对其认识的提高,临床诊断病例逐渐增多,但术前容易误诊为无功能胰岛细胞瘤、腺泡细胞癌和胰母细胞瘤等。该肿瘤最早由Frantz描述,故又称Frantz肿瘤。其他名称还包括乳头状囊性肿瘤、胰腺乳头状上皮肿瘤、胰腺实性和囊性肿瘤等。1996年WHO对其重新分类命名为胰腺实性假乳头状瘤。SPTP患病率低,在胰腺肿瘤中占0．31％～2．7％。大多数SPTP患者就诊时无症状,部分因为体检发现腹部肿块后就诊,有症状者主要表现为上腹部胀痛、食欲不振等（有报道可表现为腹腔内出血）,可能与肿瘤压迫有关,缺乏特异性,因此常延误诊断。就诊时肿瘤体积往往较大。     

胰腺囊实性乳头状肿瘤1例报告

患者女，24岁，发现腹部肿物4a逐渐增大入院。查体：左腹部触及一肿物，活动，无压痛。B超及CT均提示胰腺区占位性病变。术中胰体尾下缘及横结肠系膜间见一肿物，界限清，易剥离。病理检查：灰白灰褐色肿物一块，约16cm×11cm×6cm大小，有包膜。切面囊实性，实性区灰白灰黄，质细、软，囊性区有出血，肿瘤周围有完整包膜。     

胰腺实性假乳头状肿瘤29例临床分析并国内文献复习

胰腺实性假乳头状肿瘤（solid peudopapillary tumor of pancreas,SPTP）是胰腺少见的特殊类型肿瘤,占胰腺肿瘤的0．2％～2．7％。该病发病率低,无典型临床表现,影像学检查无明显特征,较易误诊。1959年Frantz等首次报道此病,2000年世界卫生组织将其统一命名为胰腺实性假乳头状瘤。     

胰腺实性假乳头状肿瘤的外科治疗

胰腺实性假乳头状肿瘤(SPTP)是一种交界恶性的胰腺实体肿瘤,治疗方法以手术切除为主,目前主要采用肿瘤局部切除术、胰腺节段切除术、肿瘤扩大切除术,手术方式的选择取决于对肿瘤恶性程度的判断,术后并发症以胰瘘为主,保守治疗有效,完整切除肿瘤后,患者可获得长期生存。放射、化学治疗等辅助治疗效果尚不明确。     

胰腺实性假乳头状肿瘤66例临床病理分析

胰腺实性假乳头状肿瘤（solid pseudopapillary tumor of the pancreas,SPTP）是一种相当少见、组织发生尚未定论、具有低度恶性潜能的肿瘤.临床一般无特殊症状和体征,术前诊断较为困难.本研究回顾性分析66例胰腺实性假乳头状肿瘤,就其临床病理特征进行分析总结.     

Synchronous pancreatic solid pseudopapillary neoplasm and intraductal papillary mucinous neoplasm

Solid pseudopapillary neoplasm (SPN) is a rare and low-grade malignant pancreatic neoplasm composed of poorly cohesive monomorphic neoplastic cells forming solid and pseudopapillary structures with frequent hemorrhagic-cystic degeneration. Intraductal papillary mucinous neoplasm (IPMN) is a pancreatic exocrine tumor composed of intraductal papillary growth of mucin containing neoplastic cells in the main pancreatic duct or its major branches. In the case presented here, a 53-year-old, Japanese man was found to have multiple cystic lesions and dilatation of the main pancreatic duct in the neck of the pancreas. Histological examination revealed a main-duct and branch-duct type IPMN, of the gastric-type, involving the neck of the pancreas, associated with a 0.5 cm SPN in the caudal side of the IPMN. We diagnosed this case as synchronous SPN and IPMN. As far as we know, only one other case of synchronous SPN and IPMN has been reported. Both the present case and the previously reported case showed abnormal nuclear expression of β-catenin in SPN, whereas IPMN showed no abnormal nuclear expression. These results suggest that β-catenin abnormality is not a common pathogenetic factor of synchronous SPN and IPMN.

Intraductal oncocytic papillary neoplasm of the pancreas: A systematic review

BackgroundIntraductal oncocytic papillary neoplasm of the pancreas (IOPN–P) is a rare subtype of intraductal papillary mucinous neoplasm (IPMN). This study was performed to summarize the clinicopathological features and management of IOPN-P.MethodsEnglish-language articles were searched from MEDLINE and EMBASE from the first report of IOPN-P in 1996 until 1 May 2019 following the methodology in the PRISMA guidelines.ResultsIn total, 66 patients from 24 full articles were included in the final data analysis. The patients’ average age was 61 years, and the male/female ratio was 1. Most lesions were large (average size, 5.50 cm), located in the pancreatic head, and found either incidentally or by uncharacteristic abdominal symptoms. IOPN-P was usually a cystic and solid lesion with or without mural nodules on radiological examination. A definitive diagnosis was often acquired from fine needle aspiration biopsy or postoperative pathology. All tumors were diagnosed as carcinoma in situ or minimally invasive carcinoma, necessitating surgical resection. The prognosis of IOPN-P was better than that of other IPMN subtypes, even when metastasis occurred. Recurrence after surgical resection of IOPN-P was rare.ConclusionsIOPN-P is rare among IPMN subtypes with unique pathological characteristics. Because of the nontypical symptoms and radiological findings, a definitive preoperative diagnosis usually depends on multimodal examinations. Management and surveillance of IOPN-P after surgical resection should be differentiated from those of other pancreatic benign cystic lesions because of its relative malignancy, but IOPN-P should also be differentiated from other IPMN subtypes and malignant cystic tumors because of its favorable prognosis.

Validation of serum tumor biomarkers in predicting advanced cystic mucinous neoplasm of the pancreas

BACKGROUND Early detection of advanced cystic mucinous neoplasms[(A-cMNs),defined as high-grade dysplasia or malignancy]of the pancreas is of great significance.As a simple and feasible detection method,serum tumor markers(STMs)may be used to predict advanced intraductal papillary mucinous neoplasms(IPMNs)and mucinous cystic neoplasms(MCNs).However,there are few studies on the usefulness of STMs other than carbohydrate antigen(CA)19-9 for early detection of A-cMNs.AIM To study the ability of five STMs-CA19-9,carcinoembryonic antigen(CEA),CA125,CA724,and CA242 to predict A-cMNs and distinguish IPMNs and MCNs.METHODS We mainly measured the levels of each STM in patients pathologically diagnosed with cMNs.The mean levels of STMs and the number of A-cMN subjects with a higher STM level than the cutoff were compared respectively to identify the ability of STMs to predict A-cMNs and distinguish MCNs from IPMNs.A receiver operating characteristic curve with the area under curve(AUC)was also created to identify the performance of the five STMs.RESULTS A total of 187 patients with cMNs were identified and 72 of them showed AcMNs.We found that CA19-9 exhibited the highest sensitivity(SE)(54.2%)and accuracy(76.5%)and a moderate ability(AUC=0.766)to predict A-cMNs.In predicting high-grade dysplasia IPMNs,the SE of CA19-9 decreased to 38.5%.The ability of CEA,CA125,and CA724 to predict A-cMNs was low(AUC=0.651,0.583,and 0.618,respectively).The predictive ability of CA242 was not identified.The combination of STMs improved the SE to 62.5%.CA125 may be specific to the diagnosis of advanced MCNs.CONCLUSION CA19-9 has a moderate ability,and CEA,CA125,and CA724 have a low ability to predict A-cMNs.The combination of STM testing could improve SE in predicting A-cMNs.     

Spleen-preserving distal pancreatectomy following neoadjuvant chemotherapy for papillary solid and cystic neoplasm of pancreas.

Papillary solid and cystic neoplasm (PSCN) is a rare neoplasm of the pancreas with low-grade malignant potential and favorable prognosis. We report an 18-year-old girl with PSCN presenting with advanced disease. The tumor regressed with six cycles of gemcitabine and cisplantin-based neoadjuvant chemotherapy; spleen-preserving distal pancreatectomy was then done. She is disease-free at 13 months' follow-up.     

Intraductal papillary mucinous neoplasm of the ileal heterotopic pancreas in a patient with hereditary non-polyposis colorectal cancer: A case report

We report a case of intraductal papillary mucinous neoplasm (IPMN) originating from the ileal heterotopic pancreas in a patient with hereditary non-polyposis colorectal cancer (HNPCC). A 49-year-old woman had a past history of total colectomy and total hysterectomy with bilateral salpingo-oophorectomy due to colonic adenocarcinoma and endometrial adenocarcinoma 11 years ago. Her parents died from colonic adenocarcinoma and her sister died from colonic adenocarcinoma and endometrial adenocarcinoma. The clinician found an ileal mass with necrotic change and the mass increased in size from 1.7 cm to 2.2 cm during the past 2 years on computed tomography. It was surgically resected. Microscopically, the ileal mass showed heterotopic pancreas with IPMN high grade dysplasia. Immunohistochemical staining revealed positive reactivity for MLH1/PMS2 and negative reactivity for MSH2/MSH6. This is the first report of IPMN originating from the ileal heterotopic pancreas in a patient with HNPCC in the English literature.
