Abstract
Neuroendocrine tumours of the extrahepatic bile ducts are extremely rare with less than 70 cases having been reported in the literature. Neuroendocrine tumours are neoplasms of variable malignant potential that arise from the embryonic neural crest cells. They most commonly occur in young females and usually present with painless jaundice. Preoperative diagnosis is seldom made and neuroendocrine tumours are usually incidentally found during abdominal surgical intervention for other indication. Due to their indolent biological behaviour aggressive surgical treatment is recommended. We present a case of an incidentally discovered neuroendocrine tumour of the cystic duct in a 41 year old woman following laparoscopic cholecystectomy for symptomatic gallbladder microlithiasis. The present case is the 8th case of cystic duct NET and the 63rd of extrahepatic bile duct NET. While a rare location for a NET, it is important to report cases of biliary tract neuroendocrine tumours in order for their pathogenesis and physical history to be clarified.

Abstract
During routine laparoscopic surgery, the surgeon may encounter the presence of small white subcapsular liver nodules, either solitary or multiple. The lesions may mimic liver metastasis and in many cases are not demonstrated in the preoperative ultrasound or computed tomography. The aim of this article is to familiarize the laparoscopic surgeon with the incidental discovery of these nodules which represent the two types of intrahepatic benign bile duct proliferations and include biliary hamartomas, which are usually multiple benign malformations of the intrahepatic bile ducts, and peribiliary gland hamartoma, which is usually solitary and consists of a benign epithelial tumor of the liver derived from bile duct cells.

Abstract
Lymphoepithelioma-like gastric carcinoma (LELGC) has special clinicopathologic features that differentiate it from the common gastric adenocarcinoma. LELGC is a rare neoplasm of the stomach with an incidence of 1-4% of all gastric cancers and is characterized by desmoplastic stroma uniformaly infiltrated by abundant lymphocytes and plasma cells. LELGC is closely associated with the Epstein-Barr virus (EBV), with 80-100% of LELGC being EBV-positive. LELGC has a male predominance, occurs in elderly people and is usually located in the upper and middle portion of the stomach. We report a rare case of lymphoepithelioma-like gastric carcinoma located in the lesser curvature at the border of the gastric body to the pyloric antrum.

Abstract
BACKGROUND Thoraco-abdominal traumatic injuries affect the inferior part of the thoracic cavity and the superior part of the abdominal cavity. This study summarizes five years of our surgical department's experience in the diagnosis and management of thoracoabdominal trauma patients. METHODS We examined records from our surgical and emergency room departments from January 1996 to December 2000, and selected patients with thoraco-abdominal injuries. RESULTS Fifty-five patients were treated who suffered coexisting trauma of the thoracic and abdominal cavity. Males represented the majority of patients and mean age was 38.2 years. Traffic accidents were the major cause (55%) followed by criminal acts of violence (32%) and falls (13%). The most common thoracic injuries were rib fractures (40%) and simple lung contusions (35%) and the abdominal organs most commonly injured were the spleen (35%), liver (25%) and kidney (20%). Surgical interventions were performed in 68% of patients, whereas the remaining patients were treated conservatively. CONCLUSIONS Thoraco-abdominal injuries are characterized by high heterogeneity and can provide significant decision-making challenges. The accurate diagnosis of all coexisting injuries is critically important, as the diagnosis will determine surgical or non-operative management of these injuries.

Abstract
Gastrointestinal stromal tumours (GISTs) are considered to derive from the interstitial cells of Cajal or their precursors and are defined by their expression of c-kit protein (CD117) that is positive in 95% percent of cases. These are rare mesenchymatous tumours, while they represent the most common mesenchymal tumours of the alimentary tract. The majority of GISTs develop in the stomach and small intestine and more rarely in the rectum, colon, esophagus and mesentery; only 3-5% of all GISTs are located in the duodenum. The presenting symptoms include early satiation, dysphagia, bloating, abdominal pain and gastrointestinal bleeding, either acute or chronic. Surgery remains the mainstay of treatment for localized, non-metastatic, resectable GISTs. We present a case of duodenal gastrointestinal stromal tumour of the third portion of the duodenum that presented with acute upper gastrointestinal bleeding treated with segmental duodenal resection.

Abstract
Mesenteric cysts are rare cystic malformations of the mesentery. They are usually located at the iliac mesentery. Clinically most mesenteric cysts are asymptomatic, but sometimes they present with non-specific abdominal symptoms. Diagnosis can be aided using US, CT and MRI but careful interpretation of the images and high index of suspicion of this rare condition is essential for the correct diagnosis, which cannot always be preoperatively established. The therapeutic method of choice is complete surgical excision of the cyst which minimizes the possibility of recurrence. Histopathologically they are classified in six group. We present a case of a mesothelial mesenteric cyst in patient with colon cancer. The cyst was misdiagnosed as urinary bladder diverticulum in the preoperative CT scan.

Abstract
UNLABELLED BACKROUNDS: Eosinophilic granuloma is one of the rarest causes of bone tumors, especially in adults. Eosinophilic granuloma is the commonest form of Langerhans cell histiocytosis and represents the unifocal osseous form of the disease which usually affects the skull and long bones. Eosinophilic granuloma, is a benign disease in which diagnosis and differential diagnosis presents more difficulties than treatment. OBSERVATION We present a case of eosinophilic granuloma of the rib with long term follow-up of 14 years which was treated with a combination of surgery and chemotherapy. CONCLUSION Prognosis of adult eosinophilic granuloma is excellent and the recurrence rate is limited. All available treatment options, including surgery, chemotherapy, corticosteroids, radiation, and even palliative treatment have very good results and in many cases the disease seems to heal spontaneously. However the disease, due to its rarity and unknown pathogenesis still remains an enigma for the clinical doctor.

Abstract
Foreign body ingestion is an accidental or an intentional event, with most of the ingested foreign bodies passing spontaneously through the gastrointestinal tract without incidents. About 10-20% of them, especially long and sharp objects like toothpicks, will fail to pass through the entire gastrointestinal tract and may cause symptoms. Toothpick injury of the gastrointestinal tract is often associated with considerable morbidity and mortality. The complications that can be caused by toothpick ingestion are obstruction, perforation, hemorrhage, fistula formation, small bowel inflammation, sepsis and even death. Diagnosis of toothpick injury can be difficult as there are no specific physical findings or laboratory examinations which may aid the diagnosis and even imaging studies are of little help as wooden toothpicks are radiolucent. We report a rare case of incidental toothpick ingestion which caused an ileum fistula and mimicked Crohn's disease.

Abstract
Myeloid sarcoma, which is highly associated with acute myeloid leukemia, is defined as an extramedullary discrete tumor mass, consisted by immature myeloid cells or myeloblasts. Myeloid sarcoma usually involves the skin, lymph node, bone, soft tissue and testis, while involvement of the gastrointestinal tract is rather uncommon. The diagnosis depends on histological features and immunohistochemical results. We present a rare case of myeloid sarcoma, with synchronous involvement of the jejunum and the greater omentum, manifesting with small bowel obstruction.
