1/30. Primary pancreatic hydatid disease in a child: case report and review of the literature.A 9-year-old boy was admitted with acute abdomen, and a cystic mass in the pancreas was coincidentally detected by ultrasonography. Definitive diagnosis of hydatid disease of the pancreas could be made only at operation, and surgical therapy was effective.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
2/30. Cytologic features of lymphoepithelial cyst of the pancreas: two preoperatively diagnosed cases based on fine-needle aspiration.We describe the cytologic features seen in fine-needle aspiration (FNA) specimens from two cases of preoperatively diagnosed lymphoepithelial cyst (LEC) of the pancreas. Pancreatic LEC is a rare, true cyst of uncertain histogenesis that may clinically and radiologically mimic a pseudocyst or cystic neoplasm. Both our patients were middle-aged men who presented with vague abdominal pain. Computed tomography (CT) of the abdomen revealed a mass in or around the pancreas, and CT-guided percutaneous FNA (patient 1) and endoscopic ultrasound-guided FNA (patient 2) yielded paste-like yellow-gray material. Cytologic smears showed numerous anucleated squamous cells in a background of keratinous and amorphous debris. A few benign nucleated squamous cells and plate-like cholesterol crystals were also seen. Unlike LEC of the head and neck region, only rare lymphocytes and histiocytes were present. Pancreatic LEC was diagnosed based on these cytologic findings and was histologically confirmed following cyst enucleation (patient 1) and partial pancreatectomy (patient 2). We conclude that preoperative FNA and recognition of the characteristic cytologic pattern will enable conservative surgical management of pancreatic LEC. Diagn.

3/30. Ultrasound of epigastric injuries after blunt trauma.Blunt trauma to the epigastrum may result in a retroperitoneal hematoma involving the head of the pancreas and descending duodenum. Secondary effects include obstruction of the gastric outlet, obstruction of the biliary tree, and extrinsic compression of the inferior vena cava. Four patients with epigastric trauma were reviewed who had been examined by ultrasound of the abdomen. Ultrasound showed the extent of the retroperitoneal hematoma, its effect on contiguous organs, and was helpful in clinical management.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
4/30. Intracystic hemorrhage of pancreatic serous cystadenoma after renal transplantation: report of a case.Immunosuppressive therapy after transplantation increases the risk of developing neoplasms, and neoplasms of the digestive organs are very common in Asia. We experienced a patient with an intracystic hemorrhage of pancreatic serous cystadenoma during the follow-up after renal transplantation. Pancreatic cystadenomas are not frequent. Only two cases, presenting with acute abdomen, have so far been reported in the literature. The intracystic hemorrhage in our case may have been related to a rapid tumor growth due to weakened antitumor immunity and azathioprine-induced pancreatitis.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
5/30. Solitary true cyst of the pancreas in an adult: report of a case.BACKGROUND: Solitary true cyst of the pancreas is rare in adults, and the differential diagnosis of cystic lesions of the pancreas is challenging. AIM OF THE STUDY: To describe a solitary true cyst of the pancreas in an adult and discuss the differential diagnosis. methods: A 50 yr old woman presented with a mass lesion in the right upper quadrant of the abdomen. Abdominal computed tomography showed a cystic lesion, with a maximum diameter of 12 cm, between the inferior surface of the liver and the ascending colon. The cyst was homogenous and had smooth edges. On magnetic resonance imaging, a unilocular cyst was seen that was low intensity on T1-weighted images and very high intensity on T2-weighted images. No connection between the cyst and the pancreatic ductal system was demonstrated on endoscopic retrograde cholangiopancreatography. laparotomy was performed with a presumptive diagnosis of cystic tumor of the pancreas. RESULTS: On pathologic examination, the cyst was serous and was lined with a single layer of normal cuboidal epithelium that was periodic acid Schiff stain negative. Meticulous examination failed to identify honeycomb-like microcysts characteristic of serous cystadenoma. The final diagnosis was a solitary true cyst of the pancreas. CONCLUSION: The differential diagnosis of solitary true cyst from other cystic lesion of the pancreas usually is based on histology. Particular care must be taken to distinguish this lesion from macrocystic serous cystadenoma.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
6/30. Papillary and cystic tumor of the pancreas possibly concealed within a pseudocyst.A 17 year old girl, with a papillary and cystic tumor of the pancreas, probably concealed within a previous post-traumatic pseudocyst of the pancreas is described. At 10 years of age, she had received a drainage procedure for a pancreatic pseudocyst, following a blunt abdominal trauma. The histological examination of the cyst wall did not show an epithelial lining. Seven years after that, she developed anemia and a computer tomography and ultrasonography of abdomen revealed a 10 cm x 9 cm x 8 cm, cystic, multilocular pancreatic mass with solid parts. On operation, a fist-sized, solid and multilocular cystic tumor, located in the body and tail of the pancreas, and infiltrating into the colonic serosa but with no metastasis, was found and completely excised. Histologic and electron microscopic examination revealed the characteristic features of a papillary and cystic tumor of the pancreas. This report suggests that cystic lesions of the pancreas should be carefully checked to decide the best surgical therapy.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
7/30. Pancreatic lesions in von Hippel-Lindau syndrome: report of a case.von Hippel-Lindau (VHL) syndrome is a rare autosomal inherited disorder. A germline mutation predisposes carriers to the development of multiple tumors, the most common of which are hemangioblastoma, renal cell carcinoma, pheochromocytoma, and islet cell and cystic tumors of the pancreas, the kidney, and epididymis. Visceral manifestations, such as cystadenoma of the pancreas, occur late in its course. We report the case of a 20-year old woman who presented with vomiting and dizziness, most probably caused by a palpable mass in the upper abdomen, diagnosed as pancreatic cysts. She had undergone surgery for cerebellar hemangioblastoma 4 years previously. In view of her young age, preservation of pancreatic function was crucial because of the expense of enzyme therapy and the difficulties with follow-up. Therefore, we performed cyst enucleation and distal pancreatectomy, which relieved her symptoms. She has been well with no sign of recurrence for 18 months. This case highlights that a well-prepared surgical procedure can cure a patient with pancreatic cysts caused by VHL, living in difficult socioeconomic conditions.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
8/30. Clinical, imaging, and cytopathological features of solid pseudopapillary tumor of the pancreas: a clinicopathologic study of three cases and review of the literature.Solid pseudopapillary tumors are rare pancreatic neoplasms of uncertain pathogenesis that rarely metastasize and usually occur in young women. We describe the clinical, imaging, and cytopathological features of solid pseudopapillary tumor of the pancreas. We reviewed the clinical presentation, imaging, morphologic/immunochemical features, and follow-up of three women (age range 26-44). Cases 1, 2, and 3 presented with abdominal wall abscess, multiple endocrine neoplasia, and solid/cystic mass in the pancreatic head, respectively, and computed tomography of abdomen revealed solid/cystic masses with heterogeneous enhancement in body, tail and head of the pancreas, respectively. Case 2 also exhibited a left adrenal mass. Case 3 underwent endoscopic ultrasound of the pancreas, which showed a complex solid/cystic mass with septations. Sampling consisted of fine-needle aspiration (percutaneous or endosonography-guided), and additionally, core biopsy of the pancreatic mass and adrenal lesion in case 2. Aspirates and core biopsy revealed vascular structures with attached monotonous neoplastic cells in papillary-like arrays. Tumor cells had bland nuclear features with grooves, cytoplasmic periodic acid Schiff-positive hyaline globules, and associated myxoid/stromal fragments. immunochemistry expressed alpha-1-antitrypsin, alpha-1-antichymotrypsin, vimentin, and focal neuron-specific enolase. Cases 1 and 3 underwent pancreatectomy with follow-up consisting of yearly imaging and no recurrences. Case 2 proved metastatic disease to adrenal gland and no follow-up was available. In the setting of typical clinical and imaging findings, an accurate preoperative diagnosis of pancreatic solid pseudopapillary tumor can be established by aspiration cytology and immunochemistry with or without concomitant core biopsy, on the basis of which clinicians decide treatment. This tumor can behave in a malignant fashion.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
9/30. Congenital true pancreatic cyst: a rare case.Congenital true pancreatic cysts are very rarely seen in children. We report magnetic resonance imaging features of a case of congenital true pancreatic cyst with a high level of enzymatic activity which, to the best of our knowledge, have not previously been reported. A 4-month-old boy was admitted to our clinic with a history of abdominal swelling for one month. A mobile, smooth, non-tender mass was palpated on the left side of the abdomen during physical examination. ultrasonography and MR imaging revealed a bilocular cystic mass sized 9.5 x 8 x 6 cm. The spleen was displaced superiorly, whereas the left kidney was displaced posteriorly. Obliteration of the peripancreatic fat planes between the cystic mass and tail of the pancreas was observed. During abdominal surgical exploration, the pancreatic tail was larger than normal, and a pancreatic cyst arising from the tail of the pancreas was observed. Total cystectomy was performed with distal pancreatectomy. Although it is extremely rare in children, congenital true pancreatic cysts should be diagnostically considered in cases involving a cystic mass neighboring the pancreas. MR imaging is not helpful in differential diagnosis of other cysts originating from neighboring organs. Total excision with distal pancreatectomy and splenic preservation are advised for distal pancreatic cysts.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
10/30. Mediastinal pancreatic pseudocysts in children.Mediastinal pseudocyst is an unusual complication of pancreatitis, with only four cases previously reported in children. The extent of the pseudocyst can be defined by computed tomography or magnetic resonance imaging scan and preoperative aspiration of cyst fluid for amylase level can establish the diagnosis. Endoscopic retrograde cholangiopancreatography to define ductal anatomy can help plan the appropriate drainage procedure. Although exceedingly rare, the diagnosis of pseudocyst should be considered for any cystic mass in the abdomen or thorax, even in the absence of elevated amylase or history suggesting pancreatitis.- - - - - - - - - - ranking = 1keywords = abdomen (Clic here for more details about this article) |
