Highlights • 64-year-old man admitted with abdominal pain and rectal bleeding found to have thrombosis of portal and superior mesenteric veins on abdominal CT. • Managed conservatively but returned seven months later with obstruction requiring segmental small bowel resection. • Case demonstrates that mesenteric vein thrombosis can be reversed by effective anticoagulation. • Patients escaping early bowel resection due to bowel infarction may still require resection later due to stricture., Introduction The increasing frequency of use of CT in patients with acute abdomen is likely to improve the diagnosis of rarely occurring conditions/causes such as superior mesenteric vein thrombosis (MVT). Despite its severe consequences, MVT often presents with nonspecific clinical features. Presentation of case AD, a 64-year-old man was an emergency admission with vague abdominal discomfort of two weeks duration, acute upper abdominal pain, loose stools, fresh rectal bleeding and vomiting. A contrast enhanced abdominal CT showed thrombosis of the proximal portal vein and the entire length of the superior mesenteric vein (SMV) with small bowel ischaemia extending from the terminal ileum to the mid jejunal loops. Tests for paroxysmal nocturnal haemoglobinuria and Janus kinase 2 mutation yielded negative results. AD was readmitted seven months later with small bowel obstruction requiring segmental small bowel resection with end-to-end anastomosis. Abdominal CT had shown complete resolution of MVT but a small bowel stricture. Discussion Thrombosis limited to mesenteric veins results in earlier and more frequent development of infarction compared to portal combined with mesenteric venous thrombosis. Most patients may be successfully treated with anti-coagulation therapy alone. However, surgery may be required to deal with intestinal infarction or late sequela of MVT. Conclusion This case demonstrates that MVT can be reversed by effective anticoagulation. However, the price paid for a mild to moderate effect on the bowel may be significant stricture later on. Patients escaping early bowel resection due to massive MVT leading to bowel infarction may still require resection later due to stricture.

Medullary thyroid cancer is a type of thyroid cancer of neuroendocrine origin. It occurs in hereditary and sporadic forms, and its aggressive behavior is associated with the clinical presentation and type of RET mutation. Total thyroidectomy remains the ideal choice of treatment. Early diagnosis and treatment are the fundamental for a 100% cure rate. In this study, we present our experience of 3 cases, along with a complete review of the literature derived from a Pubmed Database search.

INTRODUCTION Pancreatic incidentalomas are diagnosed at increased rates due to advanced pancreatic imaging. Coexistence of such lesions with another pancreatic pathology, however, is uncommon and their management might be perplexed by the anatomical location and the histological features of the lesion. PRESENTATION OF CASE A patient with obstructive jaundice was diagnosed with adenocarcinoma of the pancreatic head and underwent routine pancreatic imaging (CT) which revealed the coexistence of a small cystic lesion at the pancreatic body. Further investigation with MRCP and ERCP was unable to confirm a benign lesion and total pancreatoduodenectomy was performed. Histological examination showed a rare type of mixed serous–mucinous cystadenoma of borderline malignancy at the pancreatic body coexistent with an adenocarcinoma of the pancreatic head. DISCUSSION Coexistence of a peripheral pancreatic cystic tumor with a ductal adenocarcinoma of the pancreatic head is a very rare incidence in medical literature. The management of the peripheral lesion is not straightforward and there can be uncertainty as to the extent of the pancreatic resection that may be required. CONCLUSION Appropriate preoperative imaging has a significant impact on the definitive management of synchronous pancreatic tumors. Implications of a common pathogenetic pathway are also raised for this rare occurrence of two primary epithelial pancreatic tumors.

The incidence of soft tissue tumours, both malignant and benign, is very common. However, the coexistence of 4 types of histopathology is rare and the aim of this article is to present one treated in our Department. An 87-year-old Greek man was treated in our Department for a huge tumour on his back, under local anaesthesia. The pathology report of the specimen referred 4 types of neoplasia. This case represents this incidence in a giant liposarcoma of the back.
