Abstract
Mucocele of the appendix is a rare entity usually mimicking an adnexal tumour. There is no specific imaging or screening method to determine the diagnosis with certainty preoperatively. Appendiceal malignancy can be the underlying cause, although it is not common. We present a case of an appendiceal mucocele mimicking an ovarian tumour by both clinical and imaging (TVS and MRI) methods. This pathological condition should be considered by all the gynaecologists in the differential diagnosis of a right-sided pelvic mass.

Abstract
CONTEXT Cystic dystrophy in heterotopic pancreas is a rare and serious condition. Diagnosis is difficult because of non-specific clinical manifestations and radiologic and endoscopic imaging are pivotal. Therapeutic management is still under debate. CASE REPORT We describe a case of cystic dystrophy of the duodenal wall in heterotopic pancreas complicated with chronic pancreatitis and pancreatic cystadenoma. DISCUSSION Computed tomography and magnetic resonance are very useful in demonstrating the presence of cysts in a thickened duodenal wall but, for the most part, endoscopic ultrasonography is the most useful imaging examination. The choice of different therapeutic options is still under debate; although some authors have proposed a medical approach using octreotide or endoscopic treatment for selected patients, a pancreaticoduodenectomy is usually proposed for symptomatic patients. CONCLUSION When surgery is needed, a pancreaticoduodenectomy is preferred, reserving by-pass procedures for high risk patients. Because of the non-specific clinical manifestation and the very difficult diagnosis and therapeutic management, these patients should be studied and treated in specialized and dedicated centers.

Abstract
INTRODUCTION Cystic and neuroendocrine pancreatic neoplasms are quite rare tumors which diagnosis is often difficult due to their non specific symptomatology and limited diagnostic accuracy of conventional diagnostic instruments. Their treatment is still controversial. CASE REPORT A young woman is admitted with abdominal pain and dyspepsia. Instrumental diagnosis reveals a cystic pancreatic lesion which seems to be malignant as CEA of pancreatic liquid is increased. The patient undergoes distal spleno-pancreatectomy and postoperative histological examination found IPMN associated with MCN and furthermore there was occasional diagnosis of a small neuroendocrine tumor in the pancreatic tail. DISCUSSION A correct diagnostic approach is indispensable for a correct therapeutic approach. Radical surgical treatment is indicated in all cases of main- and branch duct IPMN and in case of MCN with signs of malignant transformation. Surgical treatment is also the gold standard for pancreatic neuroendocrine tumors if they are singular and in M0 stage. CONCLUSIONS In case of cystic and neuroendocrine neoplasms of the pancreas the preoperative diagnostic approach is often not enough to obtain a definite diagnosis. Review of literature and this case report show that a definite diagnosis can only be done after postoperative histological examination. Recent prospective studies suggest the possibility for a follow up instead of surgical treatment for some neuroendocrine tumors.

Abstract
A 53-year-old woman was wheelchair-dependent and unable to work due to an extreme increase in abdominal circumference. Closer investigation revealed an ovarian tumour. A mucinous cystadenoma of the ovary weighing more than 20 kg was removed with laparotomy. A 63-year-old woman presented with postmenopausal haemorrhage. Morbid obesity and agoraphobia had prevented her from visiting a doctor earlier. She was eventually diagnosed with stage 1C grade III endometrial carcinoma, which was treated with surgery and vaginal brachytherapy. The incidence of gynaecological tumours is increased in patients with a high BMI. This association is stronger for endometrial carcinoma than for ovarian carcinoma. Obesity has a favourable influence on the histological grade of endometrial carcinoma, and is associated with lower-stage ovarian cancer. Surgery-related complications are more common in obese patients. Determining the optimal dose of adjuvant therapy is also problematic in obese patients.

Abstract
A 79-year-old woman presented with complaints of upper abdominal pain, nausea and vomiting since a few days. Laboratory tests showed no abnormalities except for some indications of an inflammation. Based on the medical history, physical examination and findings from radiological examination, initially the diagnosis was 'chronic pancreatitis with formation ofa pseudocyst caused by alcohol abuse'. After one week the patient developed cholestatic liver function disorders with elevated serum pancreatic enzymes. A CT scan of the abdomen showed a dilated gallbladder and progression of the cystic lesion in the pancreatic head with compression of the distal common bile duct. An endoscopic retrograde cholangiopancreatography was performed and the findings fitted a diagnosis of an intraductal papillary mucinous neoplasm. Differentiation between an inflammatory or neoplastic origin of cystic lesions in the pancreas can be difficult. There is a risk ofmisdiagnosing a cystic neoplasm for a pseudocyst. This may lead to delays in making the correct diagnosis.

Abstract
BACKGROUND Cystic neoplasms of the pancreas represent between 5% and 10% of all pancreatic tumors. Due to their malignant potential, surgery is indicated. Because of the uncommon nature of this pathology, the aim of this study was to present a series of six patients who were operated on for a cystic tumor and to analyze the morphological characteristics, surgical experience and follow-up. METHODS This was a retrospective study. Clinical files were studied, as well as surgical and pathological registries from patients diagnosed with cystic neoplasms of the pancreas. Five females and one male were included with a mean age of 54 +/- 15 years. The main symptom was abdominal pain. RESULTS Clinical course and CT scan results were the criteria for suspecting the diagnosis. In 4/6 patients, the tumor was located within the body and tail of the pancreas. The most frequent intervention was distal pancreatectomy. There was no mediate operative mortality in a 30-day period. Histopathological diagnoses were three serum cystadenomas, two mucinous cystadenomas and one cystadenocarcinoma. After a 4-year follow-up, no tumor recurrences have been reported in the surviving patients. CONCLUSIONS The natural history of cystic neoplasms of the pancreas is generally benign, but complications may occur by direct invasion of neighboring structures. Clinical course, tomography, pancreatography and punction are fundamental for its treatment.

Abstract
BACKGROUND Primary retroperitoneal mucinous cystadenoma is a rare tumor only 48 cases have been reported in international literature. Patients affected by primary retroperitoneal mucinous cystadenoma/cystadenocarcinoma ranged in age from 17 to 86 years (median, 42.3 years) and the size of the cystis ranged from 5 to 35 cm (median, 16.1 cm). There is no unanimous opinion on the genesis of these tumors and, due to their extreme rarity, its histogenesis, biological behavior and the optimal management strategy remain at a speculative level. CASE REPORT We report the case of a huge borderline primary retroperitoneal mucinous cystadenoma (24 x 25 cm) in a 35-year-old woman and the strategies adopted for the diagnosis and surgical management. CONCLUSION Primary mucinous cystic tumor of the retroperitoneum was correctly diagnosed only at the time of surgery. As well as in the majority of cases reported in the literature, preoperative investigations were not able to give information about the tumor site. In spite of the short follow-up (two years), the patient's favorable course supports the hypothesis that primary retroperitoneal mucinous cystadenoma may be treated in the same manner as a primary ovarian tumor of the same grade and comparable stage.

Abstract
PURPOSE To identify differential findings of biliary cystic intraductal papillary mucinous tumor (IPMT) and biliary cystadenoma/cystadenocarcinoma on CT images. MATERIALS AND METHODS Records of 7 patients with biliary cystic IPMT and 17 patients with biliary cystadenoma/cystadenocarcinoma were accessed. A pathologist reviewed gross morphologic and microscopic findings and confirmed the diagnosis. Two radiologists who were blind to the pathologic diagnosis reviewed CT images regarding size of cystic mass, mural nodule, septa, calcification, dilatation of the proximal, and distal bile ducts to the tumor, and the results were analyzed using multivariate analysis. RESULTS Mural nodule and dilatation of the bile ducts distal to the cystic tumor were more commonly seen in patients with cystic IPMT than in patients with biliary cystadenoma/cystadenocarcinoma and these are statistically significant, the P values being 0.029 and 0.016, respectively. Size of the cystic tumor, presence of septa, calcification, and dilatation of the bile duct proximal to the cystic tumor were not statistically different. CONCLUSION Biliary cystic IPMT could be differentiated from biliary cystadenoma/cystadenocarcinoma on CT images based on the presence of mural nodules and dilatation of the bile ducts distal to the cystic tumor.

Abstract
Mucinous cystic tumors (MCTP) are uncommon borderline lesions of the pancreas that may often be misdiagnosed as pseudocysts and have unknown propensity to malignity. During the last two decades in our clinic of 38 patients with cystic lesions of the pancreas two presented MCTP: a 48-year-old woman with a cyst located in the body and tail of the pancreas and a 59-year-old man with a tumor situated in the head of the gland producing an obstructive jaundice. Ultrasonography and computer tomography confirmed the presence of the cystic mass in both patients but the precise diagnosis was made only after the histologic examination of the removed lesions. With an attempted curative resection: distal pancreatectomy with preservation of the spleen in the first case and a Whipple procedure in the second one, both cases were cured. Pathology do not reveal malignant transformations. Both patients were alive, had no complaints or recurrences at 12 and 24 month after surgery. The treatment of choice in such cystic tumors is surgical removal as untreated these lesions may progress to neoplastic degeneration.

Abstract
Benign mucinous cystadenomas MCA are rare benign neoplasms in the pediatric age group. Only 19 cases have been described before, and they often present as large abdominal masses. We present a 12-year-old patient that had a huge mass arising from the left ovary causing bilateral hydronephrosis and renal insufficiency. The final pathology revealed a benign MCA. Patients with mucinous tumors usually present late, this may lead to renal insufficiency secondary to urinary outflow obstruction. Unilateral salpingo-oophorectomy is usually sufficient treatment for these cases. The diagnosis of MCA should be considered in children who present with huge pelvi-abdominal masses. Early recognition and intervention are necessary to avoid potential complications.

Abstract
OBJECTIVE To evaluate the diagnostic and prognostic value of serum CA19-9, CA125 and CP2 in mucinous ovarian tumors. METHODS In this retrospective study, the serum CA19-9, CA125 and CP2 levels of 273 hospitalized patients with ovarian tumors of either mucinous or non-mucinous type were analyzed. RESULTS (1) CA19-9 had the biggest area under curve (AUC) in mucinous tumors followed with CA125 while CA125 and CP2 had bigger AUC in non-mucinous tumor. (2) For the diagnosis of mucinous tumors, CA19-9 and CA125 combination showed a greatly increased sensitivity compared with CA19-9 or CA125 alone (93.8% versus 75.0% and 66.7%, P<0.05) with no significant improvement of the specificity (P>0.05). For the diagnosis of non-mucinous tumors, CA125 and CP2 combination showed an increased sensitivity compared with CA125 or CP2 alone (85.0% versus 80.7%, P>0.05, 85.0% versus 70.6%, P<0.05) with no significant improvement of the specificity (P>0.05). (3) Seventy percent of tumor marker-positive patients could undergo cytoreductive surgery. Compared with those who could not undergo cytoreductive surgery, they were more likely to have normal tumor marker two months after surgery (P<0.05) and longer interval to re-elevation of tumor markers (P>0.05), with lower recurrence and death rate (P<0.05). All of the 20 tumor marker-negative patients could have cytoreductive surgery with only 10% recurrence. (4) CA19-9 increased mainly in recurrent mucinous tumor, while CA125 increased dominantly in recurrent non-mucinous tumor. (5) The survival rate of CA125 and CP2 positive patients was much lower than CA125 and CP2 negative patients (P<0.05), while the survival rate was similar between CA19-9 positive and CA19-9 negative patients. CONCLUSIONS CA19-9 is a sensitive index for diagnosis of mucinous ovarian tumors. Combination of CA19-9 with CA125 can improve the sensitivity of diagnosis and postoperative monitoring of mucinous ovarian tumors. Combination of CA125 with CP2 is more valuable in the diagnosis of non-mucinous ovarian tumors.

Abstract
Mucins are aberrantly expressed in various malignancies. We immunohistochemically tested mucins expression (MUC1, MUC2 and MUC5AC) in EUS-FNA samples from pancreatic occupying lesions for the diagnostic utility. The prevalence of MUC1, MUC2 and MUC5AC expression in pancreatic cancers were 77.5% (31/40), 10.0% (4/40) and 80.0% (32/40), respectively, and in the benign pancreatic diseases 25% (4/16), 31.3% (5/16) and 43.8% (7/16). MUC1 and MUC5AC significantly overexpressed in pancreatic cancer, and MUC1 negatively related with tumor differentiation degree (p < 0.05). The prevalence of MUC1, MUC2 and MUC5AC expression in pancreatic mucinous neoplasms were 66.7% (12/18), 38.9% (7/18) and 88.9% (16/18), respectively, and in the pancreatic non-mucinous neoplasms 60.5% (23/38), 5.3% (2/38) and 57.9% (22/38). MUC2 and MUC5AC significantly overexpressed in pancreatic mucinous neoplasms, especially MUC2 in benign mucinous neoplasms (p < 0.05). Compared with cytology alone, the combination test of MUC1+cytology, and MUC5AC+cytology could achieve higher sensitivity (85 vs. 65%, 100 vs. 65%) and accuracy (89.3% vs. 73.2%, 91.1% vs. 73.2%) for pancreatic cancer diagnosis; the combination test of MUC2 + cytology, and MUC5AC + cytology could achieve higher sensitivity (77.8% vs. 38.9%, 100% vs. 38.9%), and specificity (97.4% vs. 60.5%, 71.1% vs. 60.5%) accuracy (100% vs. 51.8%, 80.4% vs. 51.8%) for mucinous neoplasm diagnosis. The panel MUC1+/MUC2-/MUC5AC+/ was higher specific in pancreatic cancer diagnosis, as well as MUC1-/MUC2+/MUC5AC+/ in pancreatic mucinous neoplasms. Our observations suggest the mucins expression profile in EUS-FNA specimens has higher value for the diagnosis of pancreatic cancer and mucinous neoplasms.

Abstract
The occurrence of mucinous cystadenomas localized to the liver and pancreas simultaneously and treated with a single surgical procedure has been described for the first time in this report. A 47-year-old woman attended the outpatient clinic complaining of abdominal pain and the appearance of an abdominal mass. On clinical examination, hepatomegaly was found. An abdominal computed tomography scan showed a large cystic lesion of the left lobe of the liver, thus causing the hepatomegaly. Moreover, the computed tomography scan showed a cystic lesion of the pancreas. Both lesions had thick walls and septa. Magnetic resonance imaging of the liver and pancreas confirmed the presence of septa within the cysts. Surgery was performed owing to the suspected malignancy. It should be emphasized that the patient had preoperatively received prophylactic treatment for hydatosis. A hepatic pericystectomy and enucleation of the pancreatic lesion were performed during the surgery. Pathology showed a mucinous cystadenoma without sign of malignancy. At the 4-year follow-up, no recurrence was found. This case is of interest for several reasons: the unusual double presentation, the treatment, and the follow-up. This case report confirms the common origin of mucinous cystic tumours of liver and pancreas.

Abstract
Primary retroperitoneal cystadenomas are extremely rare. This is the first report in literature to describe a primary retroperitoneal cystadenoma with a sarcoma-like mural nodule. A 45-year-old woman complained of a left-sided abdominal mass. A computed tomography scan revealed a cystic mass with a mural nodule, which seemed to originate from the tail of the pancreas. At laparotomy the cyst was not adhered to the pancreas but localized retroperitoneally. Histologic examination showed a mucinous cystadenoma with only foci of borderline malignancy with a mural “sarcoma-like” nodule. In view of the surgical and histopathological findings, the mucinous cystadenoma was regarded as primary retroperitoneal. This case demonstrates that in the era of radiological preoperative refinement, pathological diagnosis remains of utmost importance, especially for rare cases.

Abstract
Pancreatic cystic neoplasms are less frequent than other pancreatic tumors, but because of the wide availability and improvement of modern imaging methods, these neoplasms are being recognized with increasing frequency and it is often possible to be differentiated preoperatively not only from other cystic pancreatic disorders but also from one another. Most patients have no symptoms while clinical signs are not really useful in the clinical work up, and when they are present, they never help us to identify the type of pathology. Treatment differs with the diagnosis. Serous cystic neoplasms are uniformly benign and usually do not mandate resection unless this lesion is symptomatic. In contrast, mucinous cystic neoplasms and intraductal papillary mucinous neoplasms have a premalignant or malignant tendency, and therefore should be managed aggressively by pancreatic resection; in the absence of invasive disease, prognosis is excellent after appropriate surgery, but the presence of invasive malignancy signifies a poor prognosis. Solid pseudopapillary neoplasms have nonaggressive behavior and their management is related to the extension of the disease. The purpose of this article is to review the types of pancreatic cystic neoplasms, their diagnosis, indications for surgical treatment, and outcome.

Abstract
Pancreatic cystic lesions are detected more frequently as a result of increasing use of high-resolution cross-sectional imaging. The ability of imaging and cyst fluid analysis to predict the biologic behavior of the lesions has aroused much interest recently. A precise diagnosis is critical to help guide further management. The diagnostic criteria and the management principles have evolved dramatically over the past 10 years with the advent of endoscopic ultrasound and fine-needle aspiration. In this review, we summarize the recent publications that have examined the key issues in the diagnosis and management of cystic lesions of the pancreas.

Abstract
Mucocoele of the appendix occurs when obstruction of the appendiceal lumen results in mucus accumulation and consequent abnormal dilatation. The most impor-tant aetiology, from a surgical perspective, is either mucinous cystadenoma or cystadenocarcinoma. In the latter, a spontaneous or iatrogenic rupture of the mucocoele can lead to mucinous intraperitoneal ascites, a syndrome known as pseudomyxoma peritonei. Optimal management of mucoceles is achieved through accurate preoperative identification and subsequent careful resection. We report two cases and subsequently discuss the clinical presentation of mucocoeles, their association with pseudomyxoma peritonei and an optimal management of both conditions.

Abstract
We present the case of a 63-year-old male with intraductal papillary mucinous tumor (IPMT) of the bile ducts. We discuss the role of gadobenate dimeglumine (Gd-BOPTA)-enhanced T1-weighted MRI in the visualization of mucin flow, localization of the papillary tumor, and confirming the diagnosis of this uncommon disease.
