Abstract
Solid Pseudopapillary Tumour (SPPT) is a distinctive tumour of low malignant potential with a striking and unexplained predilection for adolescent girls and young women. Hence it is important to distinguish this rare tumour from other pancreatic tumours with similar cytomorphologic features because an accurate preoperative diagnosis is highly desirable since these patients can have long survival with adequate surgery. We report a case of the rare SPPT of the pancreas in a young girl who presented with nonspecific pain in the abdomen. Radiological investigations revealed a solid cystic mass in relation to the uncinate process of pancreas and third part of duodenum. The mass was diagnosed to be a solid pseudopapillary neoplasm of pancreas on ultrasound guided FNAC. Surgical removal of the pancreatic tumour and detailed histologic study confirmed the cytologic diagnosis. We present this case because, to date, there are few case reports on the cytological diagnosis of this tumour, about 60 cases, diagnosed by Fine-Needle Aspiration Cytology (FNAC) are reported in the literature. With widespread availability of high-quality imaging systems and a better understanding of its pathology, the number of cases reported in the literature has been steadily increasing in recent years. In our case, the cytological diagnosis was done even before the detailed imaging findings were available, the cytological features of this tumour are highly characteristic and it is possible to differentiate it from other pancreatic tumours with relative ease.

Abstract
Introduction: Solid pseudopapillary tumor of the pancreas (SPTP) is a neoplasm of uncertain origin and indolent biologic behavior with distinctive morphological features occurring predominantly in young women. This tumor has an excellent prognosis compared to neuroendocrine and acinar cell carcinoma, which are close differential diagnoses based on morphology, hence making it crucial to diagnose SPTP correctly. Objectives: To discuss the cytomorphological features of 10 cases of SPTP reported in two institutions and to evaluate the diagnostic accuracy of endoscopic ultrasound (EUS) guided fine needle aspiration (FNA) cytology in establishing the diagnosis of SPTP. Methods: Ten diagnosed cases of SPTP were retrieved from the computerized endoscopy and pathology databases of our two tertiary care institutions. Nine patients had subsequent histological follow-up available. Eight patients underwent EUS-FNA while one patient each had ultrasound and computed tomography-guided FNA. The rapid on-site evaluation was carried out in all 10 cases, and additional material was retained for cell block preparation. Immunohistochemical (IHC) stains ranging from synaptophysin, progesterone receptor, chromogranin, β-catenin, CD10, and NSE were applied on cell blocks. Histological sections of all resected specimens were reviewed, and findings were correlated with those obtained by FNA. Results: Adequate material was obtained in all ten cases. IHC stains helped to confirm the cytological impression of SPTP. Histological examination of resection specimens, available in 9/10 cases, confirmed the cytological diagnosis. Conclusions: FNA particularly that obtained with EUS guidance is an effective tool in the accurate diagnosis of SPTP.

Abstract
Solid pseudopapillary neoplasm (SPN) of the pancreas is a rare neoplasm that accounts for about 1 to 2 per cent of all pancreatic tumors. The aim of this study was to delineate the clinicopathological characteristics and surgical outcomes of solid pseudopapillary neoplasm of the pancreas. We retrospectively reviewed the clinicopathological characteristics and surgical outcomes of 18 patients who underwent surgery for SPN of the pancreas between January 1, 2001 and November 1, 2010. The patient group was comprised of 14 females and four males and the median patient age at diagnosis was 32.4 years (range 10∼68 years). Eleven of the 18 patients were symptomatic at the time of diagnosis. The type of surgery was selected according to the location and presentation of the tumor. The resection margins were negative in all patients. One patient had distant metastasis and recurrent mass node repetitively. She underwent seven operations for recurrence of SPN during the follow-up period of 218 months. Complete surgical excision is the treatment of choice for SPN of the pancreas and can give a good prognosis. Although sometimes patients have repetitive metastases or recurrences, patients undergoing complete surgical excision of the tumor will have a good outcome.

Abstract
OBJECTIVE To further delineate the clinicopathological and radiological features of solid pseudopapillary tumor (SPT) of the pancreas and summarize the surgical therapy strategy for this tumor. METHODS A retrospective review of 18 pathologically confirmed cases of SPT was performed and the clinical and pathological features, radiological findings and surgical interventions were analyzed. RESULTS The patients included 17 females and 1 male with a median age of 23 years. The median diameter of the lesions was 8.0 cm. Abdominal pain was the predominant complaint (8/18). The rest of the patients were asymptomatic and presented with a pancreatic mass detected incidentally. Radiological study revealed a well-demarcated mass which was composed of a solid-cystic portion. On post-contrast CT, the solid portions could be enhanced whereas the cystic parts remained unenhanced. With the preoperative diagnosis of SPT in 11 patients and pancreatic cyst, benign or malignant pancreatic tumor in the rest, pancreatic tumor resection was successfully completed. Surgical exploration findings, pathological characteristics and good prognosis of the patients with SPT, indicated its low-grade malignant potential. CONCLUSION In combination with clinical findings, radiological features of SPT may help to make the correct diagnosis and differentiation from other pancreatic neoplasms. Once diagnosed, given the excellent prognosis and low-grade malignancy, less aggressive surgical resection of the primary lesion is proposed.

Abstract
OBJECTIVES Solid pseudopapillary tumor (SPT) of the pancreas is very rare. This study was performed to analyze the expression of Wnt signal target genes (matrix metalloproteinase-7 [MMP-7], cyclin-D1, and c-myc) and Ki-67 in resected SPTs to determine their clinicopathologic characteristics according to their expression. METHODS From January 1995 to December 2005, 23 patients underwent pancreatic resections for SPT of the pancreas. Among 23 formalin-fixed, paraffin-embedded tissues, 12 were evaluated as a pilot study. Immunohistochemistry was performed using various detection and antigen retrieval methods to detect MMP-7, cyclin-D1, c-myc, and Ki-67. The expression of Wnt target genes was correlated with clinicopathologic features of the patients. RESULTS Solid pseudopapillary tumors of the pancreas always showed cytoplasmic/nuclear accumulation of [beta]-catenin, frequent expression of cyclin-D1, and low proliferation index. MMP-7, cyclin-D1, c-myc, and Ki-67 were not correlated with microscopic features suggesting malignant potential (P > 0.05). Tumor size was closely related to microscopic features of malignant potential and apparently has an inverse relationship with the expression of cyclin-D1 and Ki-67 (P < 0.05). CONCLUSIONS Low proliferative index and associated MMP-7 expression may cause an unpredictable clinical course in this tumor. Subtle changes in the intracellular environment, not pathologic (morphologic) changes, may elucidate the unpredictable clinical course of this tumor.

Abstract
Background The papillary cystic and solid tumour of the pancreas (PCSTP) is a rare primary neoplasm of unknown pathogenesis typically found in young women. PCSTP is a low-grade malignant tumour, which is often asymptomatic but it may present with abdominal pain. Case presentation A 38 year old female patient who presented with one day history of epigastric pain was diagnosed as PCSTP. The patient was successfully treated with distal pancreatectomy. Conclusion It is important to differentiate this tumour from other pancreatic tumours because, unlike malignant pancreatic tumours, this neoplasm does not usually metastasise and is amenable to cure after complete surgical resection. However, the cell origin and the aetiology of this tumour are not clear and further studies are warranted in its pathogenesis.

Abstract
Although non-functional islet cell tumor (NFICT) and solid and papillary neoplasm (SPN) share similar clinical and pathological features, the outcome of each is different. Because NFICT often follow a malignant course and SPN are usually benign, the correct differential diagnosis is very important. We investigated the clinical and pathological findings in 10 cases of NFICT and 12 cases of SPN, including immunohistochemical analysis for chromogranin, vimentin, neuron-specific enolase, somatostatin, alpha-1-antitrypsin, estrogen receptor, progesterone receptor, CD99, p21 and Ki-67. The current study shows that chromogranin is the most valuable marker in differentiating between the tumors (P < 0.01). In contrast to previous reports stating that SPN express the progesterone and/or estrogen receptors, which are absent in other pancreatic tumors, our results show that one-third of SPN were positive for the progesterone receptor. Downregulation of p21 was found more frequently in NFICT (40%) than SPN (17%). The mean value of the Ki-67 proliferation index for NFICT (2.77% +/- 2.53%) was significantly higher than that for SPN (0.94% +/- 0.89%; P = 0.043). These results are consistent with NFICT having more malignant behavior than SPN.

Abstract
We report herein the case of a 57-year-old female who was admitted to our hospital for treatment of rectal carcinoma and incidentally found to have a giant cystic tumor, 20 cm in diameter, in the body and tail of the pancreas. Several imaging procedures, including ultrasonography, computed tomography, and magnetic resonance imaging, showed that this tumor was round and hypovascular, and had a septum with protuberant lesions. The capsule was 3-4 mm thick with partial calcification. A preoperative diagnosis of a solid cystic tumor (SCT) of the pancreas was made, even though these tumors are rarely found in females in their fifties. Moreover, few reports of SCT with a septum have been described. Distal pancreatectomy and splenectomy were performed, and the tumor was found to be filled with massive necrotic tissue. Microscopically, the tumor was confirmed to be a SCT with a fibrous septum. We present this case due to the atypical findings, including the age of the patient and the existence of a septum caused by extracapsular growth.

Abstract
OBJECTIVE The objective was to determine whether surgical enucleation of mucinous cystadenoma of the pancreas is a safe and adequate operation. SUMMARY BACKGROUND DATA Mucinous cystadenomas of the pancreas are premalignant cystic lesions. Resection is the preferred treatment but often requires a pancreatoduodenectomy or a distal pancreatectomy with or without a splenectomy. Although these procedures can now be performed with a low mortality rate, substantial morbidity still occurs, especially in patients who have an otherwise normal pancreas. METHODS Between January 1990 and June 1997, 36 mucinous cystadenomas of the pancreas were resected at The Johns Hopkins Hospital. Most of these patients underwent pancreatoduodenectomy or distal pancreatectomy. However, 10 patients (28%) underwent enucleation of their cystic tumor. These 10 patients had a mean age of 63 years, and 6 were men. The cystic lesion was demonstrated by computed tomography in all patients. Enucleation of the cyst was performed in each patient, and four underwent another concomitant abdominal procedure. These 10 patients were followed with periodic computed tomographic scans and clinical examinations. RESULTS Enucleation took less time and was associated with less blood loss than resection. Pancreatic fistulas occurred more frequently after enucleation, but the incidence of major complications was similar between the two groups. Follow-up after enucleation averaged 43 months, and none of the patients developed late sequelae or recurrence. CONCLUSIONS This experience suggests that enucleation of mucinous cystadenomas of the pancreas can be performed safely and that the recurrence rate is low after this procedure. The authors conclude that enucleation is an adequate procedure for benign cystic neoplasms of the pancreas.
