We present a case that was diagnosed with acute cholecystitis associated with CCF by multidetector computed tomography (MDCT) preoperatively and malignant neoplasm during emergency surgery. She was finally diagnosed with gallbladder cancer after the operation and underwent a two-stage surgery for regional lymph node dissection. Gallbladder cancer can be a primary malignant cancer causing CCF, whereas MDCT is useful for preoperative diagnosis of CCF. A treatment plan in consideration of gallbladder cancer is advisable for CCF associated with malignant tumor.Surgical repair of flank hernia is not routinely performed, due to perceived technical difficulties with the surgery and risk of recurrence, or the misconception that flank hernia is solely due to a denervation injury. Due to the rareness of flank hernia in the literature, there is no general consensus on the best method of surgical repair. We present the case of a patient with a symptomatic large flank hernia following open nephrectomy, in which a hybrid technique of open and laparoscopic flank hernia repair with sublay mesh and bone anchor fixation was successfully performed with good outcome. This case highlights the benefits of the hybrid approach, which allowed a laparoscopic assessment of the defect and adhesiolysis, followed by the open repair which enabled adequate mesh overlap, fixation to surrounding tissues and bone anchor fixation.Xanthogranulomatous inflammation (XGI) is a rare process. Colonic XGI is extremely rare. We present a case report of XGI arising within an intra-abdominal cyst involving the transverse colon. A 28-year-old man presented with abdominal discomfort. He underwent a computed tomography abdomen-pelvis, which found three subcutaneous collections and a large cy
