Abstract
Pancreatic cystic neoplasms (PCNs) are increasingly detected because of the widespread use of cross-sectional imaging and overall aging population. While the majority of these cysts are benign, some can progress to advanced neoplasia (defined as high-grade dysplasia and invasive cancer). As the only widely accepted treatment for PCNs with advanced neoplasia is surgical resection, accurate preoperative diagnosis, and stratification of malignant potential for deciding about surgery, surveillance or doing nothing remains a clinical challenge. Surveillance strategies for pancreatic cysts (PCNs) combine clinical evaluation and imaging to assess changes in cyst morphology and symptoms that may indicate advanced neoplasia. PCN surveillance heavily relies on various consensus clinical guidelines that focus on high-risk morphology, surgical indications, and surveillance intervals and modalities. This review will focus on current concepts in the surveillance of newly diagnosed PCNs, especially on low-risk presumed intraductal papillary mucinous neoplasms (those without worrisome features and high-risk stigmata), and appraise current clinical surveillance guidelines.

Abstract
Pancreatic cystic lymphangioma is an extremely rare tumor. The characteristic imaging findings are poorly defined, and distinguishing between this disease and other pancreatic cyst-related tumors is very difficult. We herein report a case of a Japanese woman in her 50s with this lesion, located in the tail of the pancreas. Pancreatic cystic lymphangioma should therefore be considered in the differential diagnosis of pancreatic cystic lesions. Laparoscopic resection can be a useful, minimally invasive surgical approach for treating these cysts as well as for the treatment of benign or low-grade malignant tumors located in the pancreatic body or tail.

Abstract
Introduction: Pancreatic cystic lymphangioma (PCL) is an extremely rare benign tumor of lymphatic origin. Traditionally, it is diagnosed at surgery performed on a patient with a retroperitoneal cyst of unclear etiology. However, recently a few single case reports showed PCL was successfully diagnosed by endoscopic ultrasound with fine-needle aspiration (EUS-FNA).
Case Report: We present a new case of PCL in an 11-year-old boy who came to our hospital for swelling of the body. A contrast-enhanced computed tomography scan revealed a 7.7×4.5 cm cystic lesion involving head and neck of the pancreas. EUS-FNA was subsequently performed and diagnosis of PCL was made based on result of cytological examination and measurement of aspirate.
Conclusion: In agreement with previous reports, we show that EUS-FNA confirmed the cystic lesion in pancreas and further provided the gross, biochemical and cytological features supporting accurate diagnosis of PCL.

Abstract
Pancreatic lymphangiomas are rare, but benign neoplasms. Historically, the diagnoses in various case reports were mostly made after surgical resection. There are emerging data concerning the utility of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to differentiate it from more sinister pancreatic cystic neoplasms. A confident preoperative diagnosis with EUS-FNA is crucial to avoid unnecessary workup or surgery, especially for small and asymptomatic lesions. Here, we present a rare case of asymptomatic pancreatic lymphangioma which was diagnosed with EUS-FNA. The case highlights that a preoperative diagnosis of pancreatic lymphangioma can be made with certainty.

Abstract
Cystic neoplasms of the pancreas are found with increasing prevalence, especially in elderly asymptomatic individuals. Although the overall risk of malignancy is very low, the presence of these pancreatic cysts is associated with a large degree of anxiety and further medical investigation due to concerns about malignancy. This review discusses the different cystic neoplasms of the pancreas and reports diagnostic strategies based on clinical features and imaging data. Surgical and nonsurgical management of the most common cystic neoplasms, based on the recently revised Sendai guidelines, is also discussed, with special reference to intraductal papillary mucinous neoplasm (IPMN; particularly the branch duct variant), which is the lesion most frequently identified incidentally. IPMN pathology, its risk for development into pancreatic ductal adenocarcinoma, the pros and cons of current guidelines for management, and the potential role of endoscopic ultrasound in determining cancer risk are discussed. Finally, surgical treatment, strategies for surveillance of pancreatic cysts, and possible future directions are discussed.

Abstract
Pancreatic cysts represent a small proportion of pancreatic diseases, but their incidence has been recently increasing. Most pancreatic cysts are identified incidentally, causing a dilemma for both clinicians and patients. In contrast to ductal adenocarcinoma, neoplastic pancreatic cysts may be cured by resection. In general, pancreatic cysts are classified as neoplastic or non-neoplastic cysts. The predominant types of neoplastic cysts include intraductal papillary mucinous neoplasms, mucinous cystic neoplasms, serous cystic neoplasms, and solid pseudopapillary neoplasms. With the exception of serous type, neoplastic cysts, have malignant potential, and in most cases requires resection. Non-neoplastic cysts include pseudocyst, retention cyst, benign epithelial cysts, lymphoepithelial cysts, squamous lined cysts (dermoid cyst and epidermal cyst in intrapancreatic accessory spleen), mucinous nonneoplastic cysts, and lymphangiomas. The incidence of nonneoplastic, noninflammatory cysts is about 6.3% of all pancreatic cysts. Despite the use of high-resolution imaging technologies and cytologic tissue acquisition with endosonography, distinguishing nonneoplastic from neoplastic cysts remains difficult with most differentiations made postoperatively. Nonetheless, the definitive distinction between non-neoplastic and neoplastic cysts is crucial as unnecessary surgery could be avoided with proper diagnosis. Therefore, consideration of these rare disease entities should be entertained before deciding on surgery.

Abstract
Pancreatic cysts challenge clinicians due to their increased incidental identification on radiology imaging, the limitations of currently available diagnostic tools, and potential for malignancy. Following initial identification of an incidental pancreatic cyst, a dedicated pancreatic protocol abdominal CT scan or MRI pancreas with MRCP should be performed. Surgical resection is recommended for all surgical candidates with MD-IPMN, mixed or combined type IPMN, mucinous cystic neoplasm, and solid pseudopapillary neoplasm. Serous cystadenoma may be followed with serial imaging unless the patient develops symptoms, the cyst is larger than 4 cm or rapidly growing, or diagnostic uncertainty remains despite thorough evaluation. Surveillance is also recommended for BD-IPMN without the following features concerning malignancy: obstructive jaundice with a cyst in the head of the pancreas; solid component; nodule; main pancreatic duct ≥10 mm; or cytology suspected or positive for malignancy. BD-IPMN ≥3 cm without concerning features may also be followed carefully, although surgical resection should be considered in surgically fit patients. EUS-FNA for cyst wall cytology, CEA, amylase, and occasionally k-ras mutation are also likely aids in the diagnosis of pancreatic cysts beyond radiologic imaging. This author typically recommends EUS-FNA to further evaluate cysts larger than 1 cm without definitive indication for resection. EUS is also appropriate in patients with solid component, nodule, or size ≥3 cm to aid in decision making, especially in older patients who may be less suitable surgical candidates. A multidisciplinary approach with a team of dedicated gastrointestinal radiologists, pancreatic surgeons, gastrointestinal pathologists, and gastroenterologists is essential for managing patients with pancreatic cysts.

Abstract
A 73-year-old man presented with a 5-month history of intermittent nausea, vomiting, central abdominal discomfort and a 17-pound weight loss over the past year. Laboratory testing, including a complete blood count with differential, liver function testing, amylase and lipase studies were normal. A CT scan showed a bilobed cystic lesion inferior to the body of the pancreas. An endoscopic ultrasound revealed a 5.3×3.9 cm, anechoic, bilobed cystic lesion, extrinsic to the body of the pancreas with a 1-2 mm septation and a normal pancreas. Fine-needle aspiration revealed a milky-white aspirate with negative cytology. Laboratory assessment of the cystic aspirant revealed carcinoembryonic antigen 1.7 ng/mL, amylase 148 units/L, cholesterol 300 mg/dL, and carbohydrate antigen 19-9 3 units/mL. He underwent resection of the mass, with the histopathology confirming a diagnosis of peripancreatic lymphangioma. He did well after the surgery with interval resolution of his symptoms.

Abstract
Retroperitoneal cystic lymphangiomas are rare tumors of the lymphatic system. These tumors usually present in childhood and are often diagnosed incidentally with imaging procedures. Although benign, they can grow to large sizes and become symptomatic due to their compressive effects. They can cause diagnostic dilemmas with other retroperitoneal cystic tumors including those arising from the liver, kidney, and pancreas. Endoscopic ultrasound (EUS) has become an invaluable tool in the assessment of cystic lesions in the region of the pancreas. This case describes a 66-year-old female who presented with 3 months of abdominal pain. Radiographic imaging was suggestive of a cystic lesion in the region of the pancreas. EUS was performed confirming a cystic lesion adjacent to the tail of the pancreas with subsequent fine needle aspiration fluid analysis consistent with a cystic lymphangioma.

Abstract
BACKGROUND Lymphangioma of the pancreas is an extremely rare benign tumour of lymphatic origin, with only four cases diagnosed by EUS-FNA reported to date. METHODS AND MATERIALS Five cases of either cytologically or histologically diagnosed pancreatic lymphangioma with pre-operative cytological analysis by EUS-FNAC were reviewed. RESULTS All patients were female, with a mean age of 56.4 years. By imaging, the cystic lesions ranged in size from 2 to 7 cm (mean 4.5 cm) and were mainly located in the head of the pancreas. All cysts had thin walls and no cyst demonstrated a mural nodule. Diagnosis based on imaging features was benign in all cases due to the absence of high-risk features. Four samples were sent for biochemical analysis, which showed low CEA levels (range, <0.5-19.4 ng/ml; mean, 5.45 ng/ml) and CA 19.9 and CA 72.4 levels within normal range. All cyst fluids showed numerous small lymphocytes with no atypia; no epithelial cells were present, including no gastrointestinal contamination. Flow cytometry in two cases showed T lymphocytes with a mature phenotype. Surgical resection in two patients confirmed the cytological diagnosis. Benign clinical follow-up was available in three patients at 2, 3 and 3.5 years. CONCLUSION A multimodal approach to cytological diagnosis (combining clinical, radiological and cyst fluid gross, biochemical and cytological characteristics) can lead to the diagnosis of this cystic neoplasm and distinguish it from other more common cysts in the pancreas, potentially avoiding the need for unnecessary surgery.

Abstract
Lymphangioma is a benign and congenital malformation of the lymphatic system. Most lymphangiomas are preferentially located in the head and neck region. The abdominal organs are uncommon sites of origin. Several cases of lymphangioma in abdominal organs were reported, however, the pancreas is one of the rarest origins. Generally, intra-abdominal lymphangioma is asymptomatic and found incidentally, but in some cases, the patient complains of abdominal distension or a palpable mass. We describe the case of a 38-year-old male who presented with sudden-onset upper abdominal pain. Rupture of a cystic tumor of the pancreatic head was suspected, based on the findings of computed tomography, magnetic resonance imaging and endoscopic ultrasonography. Subtotal stomach-preserving pancreaticoduodenectomy was undertaken. The tumor, which was 4 × 4.5 × 8 cm in size, was pathologically diagnosed as a cystic lymphangioma. In conclusion, pancreatic lymphangioma is mostly asymptomatic, a ruptured case causing ‘acute abdomen’ has never been reported. Since lymphangioma is benign, it could be observed with accurate diagnosis. The surgical indication would be limited to cases of symptomatic lymphangiomas.

Abstract
Cystic lymphangioma of the pancreas is a rare benign vascular tumor. Its histogenesis is still hypothetical and preoperative diagnosis is difficult. We report a new case in a 14-year-old girl hospitalized for pain in the epigastrium and vomiting. Radiologic findings concluded in a cystic tumor of the head of the pancreas. The mass was completely excised. The pathological examination of the surgical specimen revealed cystic formations whose wall consisted of a squamous endothelial epithelium on a fibrous tissue and a few scattered lymphoid clusters, arguing in favor of a cystic lymphangioma.
