RESUMEN
Arteriovenous malformation (AVM) of the pancreas is extremely rare, although it may be increasingly diagnosed due to the widespread use of cross-sectional imaging of the abdomen. Early diagnosis of this disease is important to prevent delay of treatment and resulting fatal complications. We report a rare case of pancreatic AVM in a 48-year-old man who presented with severe chronic anemia and early gastric cancer, which made diagnosis challenging. Imaging findings, including ultrasound, computed tomography, and magnetic resonance imaging, are shown, as well as the pathologic features.

Distant metastasis of a colon carcinoma in situ has not yet been reported. We experienced a case of a sigmoid colon carcinoma in situ with common hepatic lymph node metastasis. After the first operation, we diagnosed dual intramucosal adenocarcinomas of the sigmoid colon without any regional lymph node metastasis. After the second operation, a metastatic adenocarcinoma was found in the common hepatic lymph nodes. We suggest that metastasis in cases of a colonic carcinoma in situ is rare, but possible. The parallel progression model of tumors can explain this early metastasis.

Trauma is frequently not purely penetrating or purely blunt. Such mixed trauma can result from the mechanism of injury. Recently, we encountered a patient who accidentally shot himself with a shotgun. He had a 15 x 8-cm-sized penetrating injury on left flank that did not penetrate into the peritoneal cavity and a blunt splenic injury with hemoperitoneum. Surgical and interventional treatments were performed for each injury. We present this case with a review of the related literature.

Bladder rupture following blunt trauma is rare, and no neobladder rupture following blunt trauma has yet been reported. We present a case of neobladder rupture following blunt trauma. The patient was a 65-year-old male patient who had been treated for bladder cancer via a radical cystectomy with an orthotopic ileal neobladder four years prior to this admission, and who was admitted to our emergency department due to multiple trauma after a 1.5 m fall. Primary repair was performed for the neobladder rupture.
