Cutaneous angiosarcorriias occur most commonly on the face and scalp of elderly individuals and are characterized by poor prognosis. We present a case of angiosarcoma in a 17-year-old boy not associated with any predisposing factors. The patient had three, ill-defined, 3 to 5 cm sized, erythematous, indurated subcutaneous nodules on the right upper extremity with a duration of 3 months. On histological examination, there were extravasated erythrocytes and irregular vascular channels lined by atypical endothelial cells in the dermis and subcutaneous tissue. The tumor cells appeared to dissect the collagen bundles. The patient was treated by wide surgical excision and post operative radiation therapy. However, 16 months after the operation, local recurrence was found to involve the close areas to the excision site on the right upper extremity and right axillary lymph nodes.

Higenamine was isolated originally from Aconiti tuber from Aconitum species and recently Higenamine was synthesized. The purpose of this study is to investigate the adrenergic effect of Higenamine on rabbit cardiovascular system. Blood pressure, cardic output, systemic vascular resistance and heart rate were measured after intravenous injection of Higenamine(2-100microg/kg/min). The effects of Higenamine were compared with those of other sympathomimetic drugs. The changes in the cardiovascular systems after pretreatment with Propranolol, Atenolol and Hexamethonium were also studied. The following results were obtained. 1) Higenamine increased the cardic output and the heart rate and decreased the blood pressure and the systemic vascular resistance. Those changes were dose-dependent. The duration of action of Higenamine was 5 to 8 minutes. 2) The effects of Higenamine were similar to those of Isoproterenol. The amount of Higenamine was more than 100 times the required amount of Isoproterenol in order to obtain the same casdiovascular effects. 3) The effects of Higenamine were blocked by Propranolol, The increase of cardic output and heart rate were blocked by Hexamethonium. Higenamine has stimulating action on beta1 and beta2 receptors. But Higenamine is much less potent than Isoproterenol.

Angiosarcomas are rare tumors, seen most commonly in the skin and soft tissue of head and neck region. But it has been described in numerous body sites including thyroid, breast, liver, spleen, bone, etc.. Their biological behaviors depend on the microscopic grade, site of origin, and multifocality. We report the unique cytological features of an angiosarcoma in pleural fluid. A 61-year-old woman presented with a 6 month history of dyspnea on exertion and chest pain. Chest computerized tomography(CT) revealed multiple subpleural small nodules in the right lung and widespread air space consolidation and pleural effusion in the left lung. CT of liver revealed multiple small low attenuated lesion. The smears obtained from pleural fluid showed hypocellularity with a hemorrhagic background. The tumor cells were highly pleomorphic oval or spindle in shape and presented singly, in loose groups, in knitted syncytial aggregates, and in acinar pattern. Their nuclei had vesicular chromatin with delineated, thick nuclear membranes and occasionally a large eosinophilic, prominent nucleolus. The cytoplasm was plump, thin or projected in spindly fashion. Almost all tumor cells showed variable sized intracytoplasmic vacuoles and their nuclei were sometimes crescentic by a huge vacuole. Occasional binucleated tumor cells and mitotic figures were present. Cellular debris and streaky materials were identified. Needle biopsy specimen from the pleura revealed anastomosing slit-like spaces lined by pleomorphic tumor cells. The tumor cells showed a strong reactivity for CD31 and vimentin and focal weak reactivity for factor VIII-related antigen.
