Pancreatic cystic lymphangioma diagnosed with endoscopic ultrasonographic- fine needle aspiration ; a rare mesenchymal tumor

Cystic lymphangioma is the benign proliferation of lymphatic vessels due to lymphatic system obstruction forming cysts filled with fluid. It is mostly seen in neona- tal and early childhood period, and rarely in adults. Major localisations of occurrence are cervical and axillary re- gions where it can be rarely seen in soft tissues abdomi- nal region (1). Cystic lymphangioma of the pancreas is a very rare benign neoplastic lesion counting for less than 1% of all lymphangiomas and around 0.2% of all pancre- atic tumors (2). Traditional radiological techniques are mostly insufficient for the evaluation of pancreatic cystic lesions. Therefore, the histopathological diagnosis of pancreatic cystic lymphangiomas used to be established by classical surgical incision in the past (3). Endoscopic ultrasound (EUS) has been shown to be an effective tech- nique providing high definition images of the pancreas. Cases of pancreatic cystic lymphangioma diagnosed with EUS guided fine needle aspiration (EUS-FNA) have recently been reported(2-5). We present a case of pancreatic cystic lymphangioma diagnosed with EUS- FNA in this report.
