Inferior mesenteric vein thrombosis is a rare complication after laparoscopic procedures. We presented a case of a 55-year-old woman who suffered from abdominal pain for two days. She received laparoscopic left hemicolectomy for sigmoid colon cancer two weeks ago. Computed tomography scan revealed a thrombus of the inferior mesenteric vein. The patient was managed conservatively in hospital. Her condition improved gradually without further symptoms and she was discharged after two weeks.

A 43-year-old man presented with shortness of breath for 10 days and loss body weight in the past month. Chest palpation showed gynecomastia. Computed tomography scan of the chest showed a 14-cm necrotic mass at anterior mediastinum with extension to left upper lung and multiple nodules in both lungs. The beta human chorionic gonadotropin (β-HCG) level was elevated. The patient received ultrasound-guided biopsy of the anterior mediastinal mass. Histology revealed choriocarcinoma with trophoblastic differentiation and marked necrosis.
