: Introduction: Caecal tumors, though rare, pose diagnostic challenges due to their insidious onset and anatomical features. This case study emphasises the importance of a high index of suspicion for early diagnosis and treatment of caecal carcinoma. Case Report: A 63-year-old female presented with symptoms suggestive of large bowel obstruction and acute appendicitis. Imaging revealed a tubular structure in the subcecal location, prompting emergency laparotomy. The patient underwent right hemicolectomy, revealing a 6 cm adenocarcinoma involving the terminal ileum, ileocecal junction, and cecum. Surgical biopsy confirmed moderately differentiated infiltrating adenocarcinoma. Discussion: The discussion delves into the increasing incidence of colon cancer in India, particularly in patients presenting with acute appendicitis. Diagnostic challenges, including interpreting diffusely dilated colon images, are explored. Surgical management is detailed, emphasising the need for right hemicolectomy for caecal lesions and various approaches for left-sided lesions. The multidisciplinary approach to patient care, involving medical and radiation oncologists, is highlighted for complex colorectal diseases. Conclusion: This case underscores the significance of considering caecal carcinoma in patients with intestinal obstruction, leading to appropriate diagnostic measures and timely surgical intervention. The importance of a multidisciplinary approach to patient care is crucial for effective
