Primary malignant fibrous histiocytoma (MFH) is a rare and biologically aggressive tumor. Differential diagnosis must include cystic neoplasms of the pancreas (mucinous and serous cystoadenoma or cystocarcinoma), cystic lymphangioma or mesothelioma and retroperitoneal haematoma. Making the right diagnosis preoperatively may be often difficult, but MFH may be suspected when a huge retroperitonea...

INTRODUCTION Lymphangiomas are rare, benign tumors. An intra-abdominal location of these lesions is rarer still and there are only a few reports describing laparoscopic resection for retroperitoneal lymphangiomas, especially in tumors that mimic pancreatic tumors. CASE PRESENTATION We present the case of an asymptomatic 30-year-old Japanese woman in whom a cystic tumor was found incidentally ...

CONTEXT Endoscopic ultrasound has proved to be an invaluable tool when obtaining high quality images of the pancreas. Furthermore, fine-needle aspiration of suspected lesions can be carried out simultaneously thus providing tissue samples for cytologic diagnosis. We present two cases of a rare pancreatic lesion that were diagnosed by endoscopic ultrasound with fine-needle aspiration. CASE #1: A...

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 avo...

Benign mesenteric lymphangiomas are rare intra-abdominal cysts which may be asymptomatic or present with a variety of abdominal symptoms including an acute abdomen. We are however not aware of any reports in the literature linking mesenteric lymphangioma to acute pancreatitis. We present the case of a 62-year-old man who was admitted with signs and symptoms of acute pancreatitis and a palpable ...

A pregnant woman presented to a local hospital with abdominal pain and hemorrhagic shock. Emergency caesarean section ruled out an obstetric cause and revealed a large mass, interpreted as a hematoma, with active bleeding of unknown origin. Because of her poor clinical condition, the patient was admitted to our hospital. Computed tomographic findings were suspicious for bleeding originating fro...

Objective. To report the unusual case of an adrenal lymphangioma presenting in a patient with an adrenal cystic lesion and biochemical testing concerning for pheochromocytoma. The pertinent diagnostic and imaging features of adrenal lymphangiomas are reviewed. Methods. We describe a 59-year-old patient who presented with hyperhidrosis and a 2.2 by 2.2 cm left adrenal nodule. Biochemical evaluat...
