1/9. hemoperitoneum due to a ruptured gastric stromal tumor.BACKGROUND/AIMS: gastrointestinal stromal tumors form a group of uncommon neoplasms originated from pluripotential mesenchymal cells. Many patients are asymptomatic and the tumor is discovered during an abdominal operation. Massive intraperitoneal bleeding is an exceptional complication associated with high mortality rates. Our aim is to report a case of a gastric stromal tumor in an 83-year-old patient presenting with intraperitoneal hemorrhage and hypovolemic shock, successfully operated. methods: Emergency laparotomy showed a hemoperitoneum caused by rupture of a large exogastric tumor attached to the greater curvature. Total gastrectomy and esophagojejunostomy was performed. RESULTS: Histological examination revealed proliferation of spindle-shaped cells but immunocytochemistry failed to identify specific markers of smooth muscle and neural cells. diagnosis of a gastric stromal tumor was made. Postoperative evolution was uncomplicated. CONCLUSION: Gastric stromal tumor is a relatively rare neoplasm of mesenchymal origin whose nature and prognosis is unclear.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/9. hemoperitoneum in a continuous ambulatory peritoneal dialysis patient caused by a hepatocarcinoma treated with percutaneous embolization.hemoperitoneum is an infrequent but normally benign complication in continuous ambulatory peritoneal dialysis (CAPD) patients. It can occur at any time during peritoneal dialytic treatment. hemoperitoneum is not associated with a specific disease and usually disappears spontaneously. In 20% of cases, however, hemoperitoneum is severe and requires specific investigation and emergency therapy. We report a case of hemoperitoneum in a 70-year-old, anti-hepatitic C virus-positive woman. After 48 months of CAPD treatment, a bloody peritoneal effluent developed, with severe anemia (hematocrit decreased from 30% to 20%). An abdominal computed tomography scan showed three hepatic lesions with signs of hepatic neoplasms; selective hepatic arteriography confirmed the diagnosis. Chemoembolization of the three lesions was performed, and hemoperitoneum disappeared within a few hours.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
3/9. hemoperitoneum from spontaneous rupture of a liver cell adenoma in a male with hyperthyroidism.Spontaneous liver rupture is uncommon, is difficult to diagnose, and carries a high mortality. liver cell adenoma is a rare benign liver tumor with increasing incidence in women on oral contraceptive pills, and they have been reported to rupture spontaneously. In men such a phenomenon is an extreme rarity. In animal experiments thyroid hormone is proven to play a role in the growth of liver cell-derived neoplasms as they do in normal hepatocyte proliferation. An association of liver cell adenoma and hyperthyroidism in humans has not been previously reported. We present the successful management of an unusual case of spontaneous hemoperitoneum from rupture of a liver cell adenoma in a young man with hyperthyroidism.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
4/9. Clinical manifestations of primary hepatic angiosarcoma.Malignant tumors of the liver stemming from mesenchymal origins are rare neoplasms, <1% of primary malignant hepatic lesions. Primary hepatic angiosarcoma (PHA) is the most common (36%). This study describes the incidence and clinical characteristics of this rare tumor in two medical centers, over the past 18 years. We reviewed tumor registry files at Jackson Memorial Hospital and oncology data records at Cedar's Medical Center, 1979-1997. A total of 865 primary hepatic tumors were identified, of which five cases (0.58%) were PHA; four were men, and the median age was 53 years. Symptoms and signs included: pain, anemia, fever of unknown origin, weight loss, abdominal mass, and hemoperitoneum. Median survival was only 6 months. In conclusion, primary hepatic angiosarcomas frequently are symptomatic. The presentation and preexisting factors are valuable in establishing a clinical suspicion to diagnose this rare tumor. Although imaging studies are helpful, they are not conclusive, and liver biopsy is usually required.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
5/9. Perimortem surgical intervention in cardiorespiratory arrest secondary to ruptured ovarian neoplasm.Perimortem caesarean section is the intervention of choice for unresponsive cardiorespiratory arrest during the third trimester of pregnancy. We present a case of emergent surgical intervention in an arrested patient with an abdominopelvic mass, which revealed a ruptured granulosa cell ovarian neoplasm with haemoperitoneum.- - - - - - - - - - ranking = 2.5keywords = neoplasm (Clic here for more details about this article) |
6/9. Perivascular epithelioid cell (PEC) tumors of the uterus: a clinicopathologic study of two cases with aggressive features.We report the clinicopathologic, immunohistochemical and ultrastructural features of two unusual tumors of the uterus composed of spindle and epithelioid cells strongly positive for HMB45. The two patients of 56 and 48 years of age had, respectively, hemoperitoneum and abnormal uterine bleeding. Morphologically, both tumors showed atypia and extensive necrosis. The neoplastic cells express immunohistochemically both melanogenesis (HMB45) and smooth muscle markers (actin). Ultrastructural analysis showed the presence of intracytoplasmic membrane-bound granules. We viewed these neoplasms as perivascular epithelioid cell (PEC) tumors with aggressive features. Follow-up has shown the death of one patient whereas the other is alive without disease 36 months after the surgery. The two patients were evaluated for signs of tuberous sclerosis complex, and findings were negative.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
7/9. Sequential recurrences of ovarian granulosa cell tumour 10 and 11 years after initial diagnosis as haemoperitoneum and subhepatic mass: a case report and review of the literature.adult granulosa cell tumours (GCTs) are rare ovarian neoplasms characterised by an indolent course and a propensity for late recurrence. Due to frequent endocrine manifestations most GCTs are diagnosed at an early stage. However, clinical behaviour can not be safely predicted on the basis of conventional clinicopathologic parameters. Surgery remains the cornerstone of therapeutic management. We report on a rare case of a Stage IA GCT twice recurring ten and 11 years after initial surgical treatment. The first recurrence presented as an acute abdomen due to haemoperitoneum after tumour rupture. The second recurrence presented as a subhepatic mass. This case emphasises the need for extended, lifelong follow-up even for patients with early stage, apparently completely removed GCTs. Prognostic parameters and therapeutic options especially for patients with recurrent disease are discussed.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
8/9. hemoperitoneum in the setting of metastatic cancer to the liver. A report of two cases with review of the literature.Two cases of hemoperitoneum occurring as a result of hepatic rupture due to metastatic neoplasms are presented. They represent examples of a striking and devastating but fortunately uncommon entity. The variety of primary neoplastic sites is diverse. Several possible mechanisms have been put forward to explain the event of hepatic rupture itself. Finally, it is important to note the uniformly poor survival rates following hepatic rupture despite therapy.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
9/9. hemoperitoneum secondary to exogastric leiomyosarcomas and leiomyoblastomas.A case report and review of the literature on hemoperitoneum secondary to gastric leiomyosarcomas and leiomyoblastomas are presented. hemoperitoneum is a rare and usually unsuspected complication of exogastric tumors. At present there is no evidence that intraperitoneal bleeding from these neoplasms leads to peritoneal seeding and worsened survival.- - - - - - - - - - ranking = 0.5keywords = neoplasm (Clic here for more details about this article) |
