The physical examination and laboratory test results were unremarkable. An endoscopic ultrasound (EUS) was requested and showed a 23mm cystic lesion with a well-defined and regular wall located between the IVC and the cephalic portion of the pancreas; the lesion was next to the pancreatic parenchyma, raising the hypothesis of a pancreatic cystic lesion. Fine needle aspiration (FNA) biopsy revealed a milky fluid with a yellowish color that might correspond to lymph, suggesting the possibility of a lymphangioma (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Cytological and biochemical exam of the fluid revealed 18,000 nucleated cells/μL with a lymphocyte predominance and a background of proteinaceous material; an elevated triglyceride value (2953.3mg/dL); amylase (351U/L) and carcinoembryonic antigen (CEA) (8.84ng/mL) within normal limits. All these aspects support the diagnosis of peripancreatic lymphangioma. As the patient was asymptomatic, a conservative approach with imaging surveillance was chosen. The patient will be re-evaluated in six months.<elsevierMultimedia ident="fig0005"></elsevierMultimedia>Lymphangiomas result from lymphangiectasia, which may be associated with congenital malformations, inflammatory processes, radiotherapy, surgical intervention or previous abdominal trauma.<a class="elsevierStyleCrossRefs" href="#bib0030">1–3</a> These lesions have a female preponderance (unlike our case), have been reported in all age groups and have a variable size (from 3 to 20cm).<a class="elsevierStyleCrossRefs" href="#bib0030">1,3</a> They are often asymptomatic and discovered as an incidental finding.<a class="elsevierStyleCrossRefs" href="#bib0035">2,5</a> However, the clinical presentation depends on the size, location, mass effect and complications.

Gastroenterology and Hepatology is the first journal to cover the latest advances in pathology of the gastrointestinal tract, liver, pancreas, and bile ducts, making it an indispensable tool for gastroenterologists, hepatologists, internists and general practitioners. In addition to the rigorously selected, systematically peer-reviewed manuscripts published in the research sections (Original Articles, Scientific Letters, Editorials, and Letters to the Editor), the journal also contains other important sections, such as Review Articles and Clinical Decision-Making Support, which offer in-depth reviews and updates on issues relating to the specialty.
