Epithelioid hemangioendothelioma is an unusual type of endothelial-derived vascular tumor located mainly in the soft tissues of the limbs. The present report describes a 48-year-old woman with an epithelioid hemangioendothelioma located in the liver with very unusual metastases to the myocardium. While the disease itself was controlled by adriamycin the patient died as a consequence of portal hypertension due to the abundant fibrotic component distinctive of this type of tumor. An epithelioid appearance can sometimes lead to a mistaken diagnosis of metastatic carcinoma, as happened initially in our case. The endothelial origin of the tumor must be confirmed by electron microscope identification of Weibel-Palade bodies or by immunohistochemical staining of factor VIII-related antigen. To the authors knowledge, this is the first case of myocardial metastases from an epithelioid hemangioendothelioma of the liver to be reported in English in the medical literature.

The scintigraphic features of malignant epithelioid hemangioendothelioma of the liver have not been previously documented. In particular, there are no reports on the nature of gallium uptake in these rare tumors. The case reported is a young woman with primary hepatic epithelioid hemangioendothelioma. Metastatic disease in the skull was detected on a Tc-99m MDP bone scan. A Ga-67 study demonstrated that this tumor was not gallium avid.

Duplex Doppler ultrasound (US) was used in 68 consecutive patients with focal liver lesions, including 12 hepatocellular carcinomas, one cholangiocarcinoma, 37 metastases, 15 hemangiomas, one hemangioendothelioma, and two focal nodular hyperplasias. Of the hepatocellular carcinomas, six were diffusely hyperechoic, two were hypoechoic, two were single hyperechoic lesions, and two were multifocal and hyperechoic. All ten tumors with Doppler shifts of 5 kHz or above proved to be hepatocellular carcinomas. The other two hepatocellular carcinomas showed Doppler shifts of 3 kHz. In contrast, no hemangioma showed shifts above 0.7 kHz, and ten of the 15 gave no detectable signal. Of the metastases, 20 gave no signal and 17 had signals of up to 4 kHz. Three-kilohertz signals were also obtained from a cholangiocarcinoma, a hemangioendothelioma, and focal nodular hyperplasia. Correlation with angiographic findings suggested that the high-velocity Doppler signals were associated with large pressure gradients due to arteriovenous shunting. Duplex Doppler US can therefore aid in the differential diagnosis of diffuse and focal liver lesions.

Ten patients received liver transplants for unresectable epithelioid hemangioendothelioma (EHE). At the time of transplantation, four patients had microscopic metastases to the hilar lymph nodes, and one of the four also had metastases to a rib. The fifth patient had metastases to the lung, pleura, and diaphragm. The remaining five patients were believed to be free of metastatic disease. Two of these five patients died of metastatic disease at 3 and 16 months, respectively, after transplantation. Interestingly, all five patients with metastatic involvement are currently alive 40.6 +/- 22 months (mean +/- standard error of mean [SEM]) after transplantation, although one of these patients currently has metastatic disease to the lungs and mediastinum. Thus, the projected 5-year actuarial survival rate is 76%, with two patients at risk after the third year. In conclusion, liver transplantation is a reasonable procedure for bulky, otherwise unresectable, EHE even in the presence of metastatic disease.

A rare case of a malignant hemangioma of the great toe is reported. The etiology, incidence, clinical presentation, differential diagnosis, and pathology of an hemangioendothelioma is presented. The basis for surgical treatment and medical management to rule out metastases was discussed. Amputation remains the treatment of choice for hemangioendothelioma.

A 14-month-old white male was diagnosed as having angiosarcoma of both the liver and spleen. At 17 months he developed pulmonary metastases and died. There was no apparent environmental or hormonal exposure either prenatally or during infancy. The malignant tumor probably arose from its benign counterpart (hemangioendothelioma), which was found in the spleen. This is the fifth case reported of splenic angiosarcoma in the pediatric age group (18 years or younger).

Malignant endovascular papillary angioendothelioma, a rare but distinctive vascular tumor of childhood, was first described in 1969. It was termed malignant because of its mitotic activity, areas of necrosis, and demonstrated ability to metastasize to regional lymph nodes. Despite these features it had a uniformly good prognosis. We report an example of this lesion in a 6-year-old boy that does not show malignant histologic features. Based on its good long-term prognosis and variable histologic features, this lesion is better classified as a borderline vascular tumor.

Epithelioid hemangioendothelioma (EH) is a vascular neoplasm that occurs predominantly in soft tissue and is not infrequently misdiagnosed as an epithelial neoplasm or angiosarcoma. Only a few cases of hepatic EH have been described, and a relationship to oral contraceptive (OC) use in patients with the hepatic lesions has not generally been recognized. We present a series of five patients with malignant epithelioid hemangioendothelioma of the liver. Confirmation of the endothelial origin of these tumors was provided by positive immunoperoxidase staining for Factor-VIII-related antigen in the four cases studied by that technique, and by the demonstration of Weibel-Palade bodies in two tumors examined by electron microscopy. All five patients were young women (mean age 33 years) and all five gave a history of OC use of 4-7 years' duration. The clinical course varied from indolent but progressive to rapid death. One patient who underwent resection of the primary tumor has survived 3 years without evidence of disease, and one patient with metastatic disease who was treated with radiation and chemotherapy has survived for 8 years with disease. Three patients with extrahepatic spread have died of the tumor. Early diagnosis of this distinctive tumor might offer the hope of salvage by resection or liver transplantation.

An unusual case of hemangioendothelioma of bone with regional lymph node metastasis in a 54-year-old woman is reported. The patient died nine weeks after admission of circulatory collapse. Six possibly similar cases were found in reviewing the literature. It is concluded that lymph node metastases from hemangioendothelioma of bone appear to be an extraordinary event and may represent an extremely unfavourable prognostic finding.

Eight cases of primary mesenchymal renal tumor in infants under one year of age were studied. The patients' ages ranged from one day to seven months; all but one were diagnosed within the first three months of life. There were four typical congenital mesoblastic nephromas. Two malignant mesenchymal, one intermediate case of difficult classification designated as "cellular variant" of congenital mesoblastic nephroma, and one hemangioendothelioma. All patients were alive and free of tumor 3 9/12 to 18 10/12 years after surgery. Of the four infants with congenital mesoblastic nephroma, one was treated by tumor excision alone; nearly 13 years later this patient was free of tumor. A high degree of cellularity and a high nucleus-cytoplasm ratio were features that characterized the tumor diagnosed as "cellular variant" of congenital mesoblastic nephroma. A sarcomatous gross appearance with cavitation necrosis was seen in the two instances of malignant mesenchymal nephroma; one of these metastasized to the lung, whereas in the other, though no metastases developed, all the histologic details of the previous case were reproduced, including distinct foci of necrosis and a high mitosis rate. Mesenchymal renal tumors in young infants constitute a set more heterogeneous than has been previously assumed. They should not be considered uniformly benign. As a group, they span the whole spectrum between benign, morphologically quiescent lesions, clinically and pathologically intermediate or indeterminate ones, and outright malignant tumors with a high risk of distant spread.
