Lymphangiomas are rare congenital benign tumors arising from the lymphatic system. The incidence of this disease in the pancreas is extremely rare, accounting for less than 1% of these tumors. Before introducing the review we reported a case of a 67-year-old woman with cystic lymphangioma of the pancreas. We reported the radiological investigations carried out preoperatively and the treatment performed. The review tries to identify the features described in literature of the pancreatic lymphangioma. We have performed a PubMed research of the world literature between January 1 st 2000, to November 31 st 2017, using the keywords [Lymphangioma pancreas], [diagnosis], [CT lymphangioma] and [MRI lymphangioma]. We have found 158 articles, of which about 100 were case reports. Based on our search criteria, we have identified 31 pancreatic lymphangioma in literature reporting their imaging characteristics. According to our report and to several authors in literature the diagnosis of cystic pancreatic lymphangioma should be considered as a differential diagnosis of pancreatic cystic lesions (PCLs). The role of imaging exams (CT and MRI) can help to identify and suspect this possibility of diagnosis. The endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) can have a potential role to reach the correct diagnosis.

HighlightsThe origin from perirenal fat is very uncommon.The occurrence of hematogenous metastasis is a rare finding at the time of diagnosis.The undifferentiated and pleomorphic type are neoplasm with high grade of malignancy.In case of diagnostic doubt and in presence of recurrence, magnetic resonance imaging (MRI) may be useful because can identifying in a reliable manner the satellite localizations of the main lesion.The complete surgical (R0) resection represents the only possibility of radical treatment.Following surgical resection, the 50–100% of liposarcomas recur from residual tissue, which is the primary cause of death.Percutaneous biopsy has low accuracy in the diagnosis of retroperitoneal dedifferentiated liposarcoma (DDLS).

Highlights Choledocholithiasis in Roux-en-Y patients is a therapeutic challenge for both surgeons and endoscopists. Prophylactic cholecystectomy is not recommended in bariatric surgery. Laparoscopic assisted-ERCP is a safe and feasible intervention. B-ERCP and EDGE are two valid alternatives B-ERCP and EDGE are two valid alternatives.

An inflammatory fibroid polyp (IFP) is a solitary rare benign neoplasm of the gastrointestinal tract, frequently located in the gastric antrum. IFPs account for about 0.1% of all gastric polyps. We report a case of a giant gastric inflammatory polyp of 2.5 cm × 7 cm that determines a gastric outlet obstruction called "ball valve syndrome" mimicking a gastrointestinal stromal tumor (GIST) and a gastric lymphoma, with an intestinal obstruction of high origin. Therefore, due to acute presentation we have decided to submit the patient to a subtotal gastrectomy. The patient was discharged two weeks later, asymptomatic. At 14 months of follow-up, patient is disease free at abdominal CT and OGDS. Depending on their size and location, IFPs can be associated with unspecific symptoms. Giant IFPs of the gastric antrum or the duodenum can determine an intermittent gastric outlet obstruction called "ball valve syndrome". Endoscopic biopsies are unhelpful and right diagnosis can be reached only with resection. In fact, only about 10% of the gastric lesions are diagnosed correctly prior to resection. Surgical treatment with complete resection with safe margins is curative. Giant IFPs are rare benign lesions whose atypical presentation can mimic GISTs, lymphomas or carcinomas. Clinical and radiological findings may not clarify the right diagnosis until histopathological evaluation aided with immunohistochemical analysis. The resection of IFPs with negative margins is curative with a good clinical outcome. In acute presentation, like in our case, surgery is the mainstay of treatment.
