1/1438. Metastatic endometrial cancer in lung and liver: complete and prolonged response to hormonal therapy with progestins.A double complete and prolonged response of metastatic endometrial carcinoma to medroxyprogesterone is reported. A 61-year-old woman with metastatic endometrial carcinoma in lung and liver achieved a complete clinical response with medroxyprogesterone lasting for 2 years. She discontinued the therapy by herself and developed a pulmonary relapse, which disappeared after retreatment with the same hormonal therapy. At present, she is alive without evidence of disease 6 years after starting progestins for metastatic disease and 14 years after treatment of the primary tumor. Progestin therapy in metastatic endometrial carcinoma is discussed, emphasizing the factors predicting response.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/1438. liver transplantation for metastatic hemangiopericytoma associated with hypoglycemia.We report a case of successful liver transplantation in a young man with metastatic hemangiopericytoma confined to the liver. He had a primary retroperitoneal hemangiopericytoma removed in 1982 and was diagnosed as having liver metastases 8 years later. Subsequently, he developed hypoglycemia, which did not respond to chemotherapy. hepatectomy and transplantation resolved his hypoglycemic attacks. He remained well and symptom free for 4 years. liver transplantation can provide effective palliation and should be considered in carefully selected patients with localized metastatic cancer.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
3/1438. Severe thyrotoxicosis due to hyperfunctioning liver metastasis from follicular carcinoma: treatment with (131)I and interstitial laser ablation.Liver metastases from differentiated thyroid tumors are unusual clinical findings, and are only rarely hyperfunctioning. We report a case of thyrotoxicosis caused by a huge and surgically unresectable liver metastasis from follicular thyroid cancer, unresponsive to treatment with large doses of thionamides. To avoid the hazardous side effects of (131)I treatment in a severely thyrotoxic patient, a preliminary debulking of the liver mass was performed by means of percutaneous interstitial laser photocoagulation. Three treatments (total energy delivery: 7200 J) were performed under ultrasound guidance, with no serious complications, during a 2-week period. One month later, serum thyroid hormones had decreased, general condition was improved, and magnetic resonance evaluation revealed large and well-defined areas of necrosis of metastatic tissue. During the following 10 months, the patient underwent 3 radioiodine treatments. Eighteen months after diagnosis, thyroid hormones were within normal levels, liver mass decreased, and the clinical condition markedly improved. The combination of percutaneous interstitial laser photocoagulation treatment and radioiodine therapy made possible the effective management of a hyperfunctioning and surgically untreatable liver metastasis from thyroid follicular carcinoma, avoiding the side effects of (131)I therapy in a thyrotoxic patient and increasing the effectiveness of radioiodine-induced neoplastic tissue ablation.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
4/1438. Multiple hepatic angiolipomas: a case report and review of literature.Follow-up of two hepatic angiolipomas in a patient without evidence of tuberous sclerosis is reported. Initially, the lesions presented as homogenously enhancing masses, which were nearly isodense to normal liver tissue on plain CT scans. focal nodular hyperplasia was assumed. One year later, fat was detected in the growing tumors and percutaneous core biopsy revealed hepatic angiolipomas. natural history of these rare lesions is unknown, and this is to the best of our knowledge the first observation of fatty metamorphosis in such a benign, mesenchymal hepatic neoplasm.- - - - - - - - - - ranking = 0.053513316239063keywords = neoplasm (Clic here for more details about this article) |
5/1438. Epstein-Barr virus-associated leiomyosarcoma of the thyroid in a child with congenital immunodeficiency: a case report.We report an unusual case of multifocal leiomyosarcoma involving the thyroid gland, liver, and right lung in a child with congenital immunodeficiency disease. The smooth muscle nature of these neoplasms was confirmed by immunohistochemistry and electron microscopic studies. in situ hybridization showed large amounts of Epstein-Barr virus messenger rna within the tumor cells. Although Epstein-Barr virus-associated smooth muscle tumors have been reported in children with AIDS and after organ transplantation, we are unaware of any case report in congenital immunodeficiency disease.- - - - - - - - - - ranking = 0.053513316239063keywords = neoplasm (Clic here for more details about this article) |
6/1438. Prenatal sonographic features of embryonal rhabdomyosarcoma.We describe a case of fetal rhabdomyosarcoma detected during the third trimester of pregnancy by prenatal sonography. At 33 weeks' gestation, sonography performed because of suspected polyhydramnios showed a solid mass of 120 x 54 mm arising from the anterior wall of the fetal thoracic cage. Another mass within the left maxillary area which originated from the left orbital floor was also detected. In the abdomen, there were multiple round masses in and around the liver. As the previous scan at 28 weeks had appeared normal, the multiple masses which became visible and enlarged rapidly in different locations led us to believe that there was fetal cancer. The most likely diagnosis was rhabdomyosarcoma (which was later confirmed), because it is the most prevalent soft-tissue tumor in children and may develop within or outside muscle anywhere in the body and at any age. Two other reported cases which were detected by prenatal ultrasound examination are also discussed.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
7/1438. radiation induced liver injury detected by particulate reticuloendothelial contrast agent.radiation induced liver injury detected by a particulate reticuloendothelial MR contrast agent is described in a patient with metastatic colon cancer. The irradiated hepatic parenchyma failed to darken after ferumoxide administration. This finding suggests that detection of metastatic disease after ferumoxide contrast agents may be impaired in patients who have previously received upper abdominal radiation treatment.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
8/1438. A case of biliary cystadenocarcinoma of the liver.We describe a case of biliary cystadenocarcinoma of the liver, a very rare malignant tumor, in a 40-year-old man referred to our hospital because of sporadic abdominal pain. A left lobectomy of the liver was performed, and macroscopic examination of the resected specimen revealed prominent papillary projections in a multiloculated cystic tumor containing mucinous material. Histologic examination of the specimen showed a biliary cystadenocarcinoma without mesenchymal stroma, associated with a cystadenoma. cystadenoma with mesenchymal stroma (CMS), which occurs exclusively in women, is generally regarded as a precancerous lesion, and patients with biliary cystadenocarcinoma with mesenchymal stroma have a good prognosis. cystadenoma without mesenchymal stroma arises in both men and women. However, the origin and precancerous lesions of cystadenocarcinoma are unknown. Moreover, the prognosis of patients with biliary cystadenocarcinoma without mesenchymal stroma is poor, especially in men. The cystadenoma without mesenchymal stroma in our patient was considered a precancerous lesion. The present patient has shown no evidence of recurrence in the 8 years after hepatic resection. Previously reported cases of cystadenocarcinoma without mesenchymal stroma, especially those in men, have had a poor outcome. A good outcome in men is very rare.- - - - - - - - - - ranking = 0.75keywords = cancer (Clic here for more details about this article) |
9/1438. A case of aberrant pancreatic cancer in the jejunum.We report a case of aberrant pancreatic cancer of the jejunum in a 63 year-old man. The patient was admitted to our hospital with epigastric discomfort and vomiting due to obstruction of the jejunum. laparotomy revealed a submucosal tumor on the jejunum with multiple liver metastases. Histological examination showed the tumor to be a well differentiated tubular adenocarcinoma originating from aberrant pancreatic tissues lacking islets. Only 1 case of aberrant pancreatic cancer in the jejunum has been previously reported in the literature.- - - - - - - - - - ranking = 1.5keywords = cancer (Clic here for more details about this article) |
10/1438. cryosurgery for unresectable primary hepatocellular carcinoma: a case report and review of literature.Primary liver cancers are a significant cause of both morbidity and mortality. Although surgical resection remains the treatment of choice for these tumors, only 10 to 20 per cent of the primary liver tumors are found to be resectable. Presently, the options for these patients include liver transplantation, cryosurgery, or nonsurgical therapy, such as transarterial chemoembolization. Techniques such as alcohol injection, interstitial radiotherapy, laser hypothermia, and radiofrequency electrodissection have all been attempted with limited success. We present a case of a 68-year-old woman with a 10-year history of liver cirrhosis secondary to chronic active hepatitis c. A lateral segmentectomy was recommended but could not be done due to severe underlying cirrhosis. cryosurgery aided by intraoperative ultrasonography was performed successfully. The patient developed recurrent disease at 58 months and died with disease at 62 months. Advances in instrumentation and intraoperative ultrasonography are making cryosurgery a viable surgical therapeutic alternative in the management of patients with unresectable hepatocellular carcinoma. The procedure can be performed safely with low morbidity.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
