Hemangioendothelial sarcoma of the penis in a 44-year-old man was treated by preoperative radiation, penectomy, and chemotherapy. The patient was free of evident disease 2 years later. Electronmicroscopy showed differentiated vascular structures at the periphery of the lesion and anaplastic cells throughout the remainder of the tumor.

The arteriographic findings in two cases of hemangiosarcoma of the spleen with liver metastases are described. These are the second and third reported cases of angiographically demonstrated malignant splenic tumors of vascular origin. Despite the absence of tumor vessels, there were multiple vascular takes in the arterial through the venous phase, mimicking benign cavernous hemangioma. Multiple metastases in the liver were the only clue to malignancy. Arteriography combined with liver-spleen scintigraphy not only provides information which is valuable in the preoperative diagnosis but also aids in management of the patient.

Angiosarcoma of the intima is a very rare tumor. The authors report a case which involved early metastases to the periphery of the leg. Cramping pain, circumscribed clusters of cells, and gangrene appear to be characteristic and should be kept in mind, as this condition imitates occlusive arteriosclerotic disease.

A case of angiosarcoma felt to arise from a vein within the radial nerve is presented. Endovascular angiosarcoma arising in a vein is unusual and only one case of angiosarcoma in a peripheral nerve has been previously reported. Microsurgery followed by radiation has led to a 36-month tumor free survival.

A single digital angiosarcoma was excised by a carbon dioxide laser with small portions of this tumor excised by the scalpel and the high-frequency electrosurgical knife. The patient has been followed for 6 years without any local recurrence or additional lesions. There is a brief summary of investigative studies with lasers in benign and malignant vascular tumors.

Two cases of angiosarcoma of the breast are presented. In spite of the often differentiated histologic pattern, this neoplasm is highly malignant and has a very poor prognosis due to its proclivity for hematogenous metastases. A short review of the recent literature corroborates this.

Two surviving patients treated for angiosarcoma of the breast are presented, along with a summary of the previous 44 reported cases. Because of early vascular metastasis and indistinct tumor margins, early excision with very wide margins, including total mastectomy, surrounding muscle and bone, is necessary.

Although 82,5% of the total body weight consist of mesenchymal tissues, only 1%--3% of all malignant tumors are soft tissue sarcomas. The necessary irradiation dose can only be determined after an exact histopathological diagnosis; therefore this diagnosis has to be made prior to the radiotherapy. Except the fibro- and liposarcomas, all sarcoma form very early lymphogenic metastases. All sarcomas show a remarquable tendency to form recurrences. Surgery is the primary therapy. After that, an irradiation of the tumor region and the regional lymph nodes should be effected under all circumstances. We have treated and checked up 749 patients. After this therapeutic method, the five-year survival rate in the stages T1 and T2 is 60% for the myxosarcoma, 67% for the angiosarcoma, 41% for the fasciculated sarcoma, 40% for the globocellular sarcoma, 30% for the polymorphous sarcoma, 69% for the fibrosarcoma, and 61% for the leiomyosarcoma.

An osteolytic bone tumor was found in a 12-month-old male NZB mouse. Macroscopically and histologically this tumor was angiosarcoma originating in bone with distant metastasis present in the spleen. The primary tumor was successfully transplanted in the back subcutaneous tissue of syngeneic mice, and the characteristics of the transplants, were found to be similar to those of the primary tumor. The ultrastructure of tumor is described.

Ten cases of angiosarcoma of the liver have been diagnosed in Shawinigan, Quebec since 1955. All have occurred in men who worked in a vinyl chloride polymerizing plant. Cigarettes and alcohol do not seem to be associated with this tumor. The amount of vinyl chloride to which these people were exposed, according to information obtained through questionnaires, appears elevated. Angiosarcoma of the liver is accompanied by a fibrosis of the liver which may precede its appearance. In describing the Canadian cases of angiosarcoma, this study attempts to shed more light upon the causal relationship between vinyl chloride monomer and angiosarcoma of the liver and thus to provide some clues to understanding the pathogenesis of this disease.
