1/145. Infantile hemangioendothelioma of the pericranium presenting as an occipital mass lesion. Case report.The case of a newborn infant with a large midline mass in the occipital region is presented. skull x-ray films demonstrated multiple radiolucent defects in the occipital bone. A computerized tomography scan revealed an extracranial mass lesion with marked contrast enhancement. A magnetic resonance image demonstrated that the venous drainage of the lesion passed through the occipital bone into the dural venous sinuses. The anatomy of the hindbrain was normal. The neonate was treated by complete surgical removal of the mass. The histopathological diagnosis was infantile hemangioendothelioma, a tumor commonly found in the liver but rarely in this location. The classification, histopathological characteristics, imaging studies, and treatment of this tumor are discussed.- - - - - - - - - - ranking = 1keywords = liver (Clic here for more details about this article) |
2/145. Two cases of secondary angiosarcoma arising from fibrous dysplasia.Angiosarcoma associated with fibrous dysplasia is very rare. We have recently experienced two cases of angiosarcoma that secondarily arose from fibrous dysplasia. The first patient, a 55 year-old man, had noticed a deformity in the right upper arm since he was five years old. At the age of 25 years, polyostotic fibrous dysplasia was diagnosed by X-ray examination. The patient complained of swelling and pain around the left shoulder. The diaphysis of the humerus was mostly non-observable due to severe bone destruction by tumor invasion and there was a large soft tissue tumor. biopsy examination revealed grade II or III hemangioendothelioma with typical histologic findings of fibrous dysplasia. After interscapulothoracic amputation for wide tumor resection, he died of DIC. autopsy revealed multiple liver metastatic lesions of angiosarcoma. The second patient was a 66-year-old woman. She presented with a pathological fracture in the right tibia, due to an osteolytic lesion with cortical bone swelling and thinning. The histologic diagnosis was fibrous dysplasia without any sarcomatous changes. However, after a 3-time recurrence, angiosarcoma arose from the same lesion. She is now still alive with disease-free period of 6.5 years after amputation.- - - - - - - - - - ranking = 1keywords = liver (Clic here for more details about this article) |
3/145. Sedation for intractable distress of a dying patient: acute palliative care and the principle of double effect.Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. The case presented is of a young man dying of recurrent epithelioid hemangioendothelioma, distressed with stridor and severe pain, whose poorly controlled symptoms were successfully treated with an infusion of propofol, titrated to provide effective comfort in the last few hours of the patient's life. The tenet of double effect, which allows aggressive treatment of suffering in spite of foreseeable but unintended consequences, is reviewed. The patient's parents were invited and contributed to the Rounds, providing compelling testimony to the power of the presence of clinicians at the time of death and the importance of open communication about difficult ethical issues.- - - - - - - - - - ranking = 1keywords = liver (Clic here for more details about this article) |
4/145. Thorotrast-induced haemangioendothelial sarcoma--a lesson from the past.Complications following a carotid arteriogram done in 1947 with Thorotrast are described in a 47-year-old man who subsequently died from them in 1970. They included a local cervical granuloma with associated haemangioendothelial sarcoma, chromosome changes characteristic of radiation damage and widespread haemangioendothelial sarcomatous deposits in brain, lung, liver, probably arising from multicentric primary sites in the bone marrow. A survey of the use of Thorotrast as a contrast medium in australia and new zealand showed that its use was extremely limited. The prinicpal complications seen have been two cervical granulomas and one hepatoma.- - - - - - - - - - ranking = 1keywords = liver (Clic here for more details about this article) |
5/145. Infantile hemangioendothelioma. A case report.The case of a 3-month-old boy with a hepatic infantile hemangioendothelioma is reported. There was no previous history of disease and no symptoms, only an incidentally found abdominal mass. The case is presented as an example of establishing the diagnosis, deciding upon the treatment, and performing the follow-up using only non-invasive imaging techniques.- - - - - - - - - - ranking = 5.9803333779751keywords = hepatic (Clic here for more details about this article) |
6/145. Hepatic hemangioendothelioma: prenatal sonographic findings and evolution of the lesion.We describe a case of hepatic hemangioendothelioma that was first suspected based on prenatal sonographic findings at 19 weeks' menstrual age. At 16 weeks, the patient presented with a markedly elevated maternal serum alpha-fetoprotein level. Serial sonographic examinations revealed that the fetus had cardiomegaly, hepatomegaly with a hepatic mass and dilated intrahepatic vessels, a single umbilical artery, and a placental chorioangioma. Arteriovenous shunting within the hepatic mass was seen using color Doppler and pulsed Doppler sonography. An enlarged artery arising from the abdominal aorta supplying the mass was demonstrated. Postnatal physical examination and radiologic studies supported the diagnosis of hepatic hemangioendothelioma. The evolution in the sonographic appearance of this hepatic lesion in utero over a 17-week period is described.- - - - - - - - - - ranking = 35.88200026785keywords = hepatic (Clic here for more details about this article) |
7/145. Infantile hemangioendothelioma treated with high dose methylprednisolone pulse therapy.Infantile hemangioendothelioma is a severe disease with a high mortality. It is characterized by multiple hemangioma affecting the skin and visceral organs. We report that high doses of methylprednisolone pulse therapy improved symptoms and signs of infantile hemangioendothelioma in a male neonate, and completely resolved the hepatic and cutaneous hemangioendothelioma on follow up.- - - - - - - - - - ranking = 5.9803333779751keywords = hepatic (Clic here for more details about this article) |
8/145. Hepatic hemangioendothelioma associated with production of humoral thyrotropin-like factor.We report on 7 patients referred for treatment of hepatic hemangioendothelioma with increased thyrotropin levels. The serum thyroxine level was decreased in 4 and increased in 2. immunohistochemistry showed positive staining of tumor, but not of normal liver tissue, for thyrotropin. We propose secretion by the tumor of a thyrotropin-like factor.- - - - - - - - - - ranking = 6.9803333779751keywords = hepatic, liver (Clic here for more details about this article) |
9/145. Infantile hemangioendothelioma.Primary hepatic tumors are uncommon in children and account for only three per cent of the tumors in children. Infantile hemangioendothelioma is a rare benign hepatic tumor arising from mesenchymal tissue. Most of the cases present before six months. An unusual presentation and progression of infantile hemangioendothelioma is reported in a 19-month-old female child. The diagnosis was arrived at by radiological and histopathological examination. The patient underwent excision surgery, following which made an uneventful recovery. On follow-up at six months, patient was asymptomatic with no evidence of recurrence.- - - - - - - - - - ranking = 11.96066675595keywords = hepatic (Clic here for more details about this article) |
10/145. Infantile hemangioendothelioma of the liver in an adult.Hepatic infantile hemangioendothelioma (IHE) is a rare benign vascular tumor of the liver found mostly in infancy and early childhood. We describe herein a tumor of the liver, morphologically indistinguishable from IHE, that presented in an adult. The patient is a 56-year-old woman with a history of ductal carcinoma in situ of the left breast and a mass in the liver. The patient underwent resection of the tumor, and after 23 months of follow-up she is alive with no evidence of expansion of the liver tumor.- - - - - - - - - - ranking = 8keywords = liver (Clic here for more details about this article) |
