Tumor rupture is a common clinical event in the process of tumorigenesis, progression, diagnosis and treatment of gastrointestinal stromal tumor, which is closely associated with tumor recurrence, metastasis and poor prognosis. Tumor rupture may be associated with some intrinsic biological aggressiveness qualities, such as large tumor size, high mitotic count, and KIT exon 11 deletion mutations involving codons 557 and 558, and may be relatively more frequent with small intestine GIST and excellent response to imatinib neoadjuvant therapy resulting in tumor tissue rapid liquefacient and necrosis. The triggering factors involve sudden increase in abdominal pressure, external pressure, collision and improper surgical operation, etc. Tumor rupture is considered as an important risk factor of recurrence after macroscopically complete resection of tumor, and an indication for determining interval or even lifelong adjuvant therapy with imatinib according to guidelines. However, there is no consensus or universally accepted definition of tumor rupture, and, consequently, its incidence varies greatly across reported series and lacks detailed epidemiological data. Without pre-defined criteria, it is difficult to assess the clinical significance of rupture. We reviewed the relevant literature and international guidelines, and generally divided tumor rupture into spontaneous rupture and iatrogenic rupture. Based on the Oslo criteria, we proposed the following six definitions for tumor rupture: (1) tumor fracture or spillage; (2) blood-stained ascites; (3) gastrointestinal perforation at the tumor site; (4) microscopic infiltration of an adjacent organ; (5) intralesional dissection or piecemeal resection; (6) incisional biopsy. The following types of minor defects of tumor integrity should not be defined as rupture: (1) mucosal defects or spillage contained within the gastrointestinal lumen; (2) microscopic tumor penetration of the peritoneum or iatrogenic damage only to the serosa; (3) uncomplicated transperitoneal needle biopsy; (4) R1 resection. In addition, we further emphasize the importance of identifying risk factors of tumor rupture, prevention and positive intervention.

Spontaneous rupture with internal bleeding of solid tumors has rarely been described at the time of diagnosis or during chemotherapy. This rare event must be regarded as a life threatening condition. In these emergency situations, control of hemorrhage, which is life-saving, can be achieved by transcatheter arterial embolization (TAE) and/or surgical resection. This report describes two infants presenting with acute hemorrhagic shock due to spontaneous tumor rupture of hepatoblastoma and neuroblastoma during chemotherapy. TAE successfully arrested the tumor bleeding and a visibly reduced the tumor size in both children. Spontaneous rupture of solid tumors occur infrequently in children, but is a life threatening situation. Careful monitoring for the occurrence of this rare event especially in very young children presenting with a large tumor mass.

Rupture of the lumbar artery is usually associated with trauma but rarely has been reported in association with anticoagulation. We present a 71-year-old man who developed spontaneous rupture of the lumbar artery leading to a retroperitoneal hematoma while receiving continuous renal replacement therapy (CRRT). The bleeding was confirmed by computed tomography and angiography and was controlled successfully using selective angiographic embolization. We suggest that spontaneous retroperitoneal bleeding should be considered in a case of sudden decrease in hemoglobin in a CRRT patient.

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage, and renal failure. Among the various hemorrhagic complications of HFRS, the spontaneous rupture of an arteriovenous malformation of the testicular vessels with a retroperitoneal hematoma is a rare finding. Here, we report a case of HFRS complicated by a massive retroperitoneal hematoma that was treated with transcatheter arterial embolization.

Vascular involvement in neurofibromatosis type 1 is rare but has the potential to be fatal. We report a case of a patient with spontaneous rupture of a left intercostal artery aneurysm, which presented as a massive left hemothorax and was successfully treated by transarterial coil embolization.

We report 2 cases of complicated spontaneous dissection of the celiac artery, which were successfully treated by a stent graft. The first patient was a 47-year-old man who presented with acute abdominal pain. CT scan showed ruptured saccular aneurysm with surrounding retroperitoneal hematoma. The second patient was a 57-year-old man with progressive dissecting aneurysm. Endovascular stent graft was placed in the celiac trunk to control bleeding, and to prevent rupture in each patient. Follow-up CT scans showed complete obliteration of a dissecting aneurysm.

Gastric lymphoepithelioma-like carcinoma is a rare carcinoma among gastric malignant tumor but has a good prognosis. The carcinoma has histologic feature characterized by small nest of cancer cells mixed with lymphoid stroma. We report a case with lymphoepithelioma-like carcinoma of stomach initially presenting as panperitonitis because of spontaneous tumor perforation. A 56-year-old man visited our emergency room because of epigastric pain. A preoperative abdominal CT scan showed a massive pneumoperitoneum in the upper abdomen, and the presence of gastric cancer in the lesser curvature of the stomach. An emergent laparotomy was performed followed by radical subtotal gastrectomy. Pathologic examination revealed that the tumor was a lymphoepithelioma-like gastric carcinoma.
