Undifferentiated pleomorphic sarcoma (UPS) is the most common sarcoma that appears in older patients, usually in the extremities and the retroperitoneum. Other locations are rare. By definition, in UPS, although the malignant cells tend to appear fibroblastic or myofibroblastic, they should not show differentiation towards a more specific line of differentiation. In this sense, we report the case of an 80-year-old patient with an initial clinical diagnosis of a locally advanced colonic neoplasm that was later confirmed as a primary mesenteric UPS. Primary mesenteric UPS are extremely rare with less than 20 cases reported. We also review the pathologic and radiologic diagnostic criteria and the natural history of these tumours.

Background: Mycobacterium avium complex (MAC) is a common pathogen causing non-tuberculous mycobacterial infections, primarily affecting the lungs. Disseminated MAC disease occurs mainly in immunocompromised individuals, such as those with acquired immunodeficiency syndrome, hematological malignancies, or those positive for anti-interferon-γ antibodies. However, its occurrence in solid organ transplant recipients is uncommon.

Adipose is a complex tissue comprised of adipocytes, immune cells, endothelial and progenitor stem cells. In humans, there are at least nine defined adipose depots, each containing variable numbers of genetically identified adipocyte clusters suggesting remarkable heterogeneity and potential functionality in each depot with respect to lipid metabolism. Although subcutaneous and visceral depots are commonly analyzed for biochemical and molecular functions, the mesenteric depot has been overlooked yet strongly implicated in lipid mediated immune surveillance.

Objective: Acute mesenteric artery obstruction is a severe cause of acute mesenteric ischemia, associated with significant morbidity and mortality. However, there is limited guidance on choosing between traditional and minimally invasive techniques comprehensively. This study introduces a selective, minimally invasive strategy designed to improve the survival and prognosis of patients with acute superior mesenteric artery obstruction.

Percutaneous vertebroplasty (PVP) is a widely utilized minimally invasive technique originally developed for the treatment of vertebral compression fractures. It has since expanded to treat osteoporotic vertebral compression fractures, pathologic vertebral fractures resulting from primary or secondary spinal tumors, and traumatic spinal fractures. Despite its benefits, PVP is associated with significant complications, the most common of which is bone cement leakage.

Introduction: In colostomy-related complications, variceal hemorrhage particularly induced by cirrhosis and portal hypertension is seldom encountered. The onset of peristome variceal hemorrhage necessitates swift and effective intervention to prevent potentially life-threatening outcomes such as hemorrhagic shock and recurrent stoma bleeding.
Case Presentation: This report details a case of repeated varicose vein hemorrhage around the stoma in a patient with liver cirrhosis.
