Abstract
Synovial sarcoma of peripheral nerve (SSPN) is rare with only 26 cases reported in English. SSPN is often mistaken for a benign or malignant peripheral nerve sheath tumor (PNST) by clinicians and pathologists. Fifteen cases of SSPN were retrieved from the pathology files of 3 institutions. All tumors arose in a nerve based on imaging and/or operative findings and the diagnoses were histologically confirmed. Neuropathic symptoms predominated in 11 women and 4 men, 19- to 62-year-old (median, 39 years) with tumors involving the ulnar (5), median (3), peroneal (3) or sciatic (2) nerve, or the L4 or T1 nerve root (2). Tumor sizes ranged from 2 to 13 cm (median, 3.8 cm). The leading clinical diagnosis was PNST (9). Treatment was surgical (14) supplemented with radiation therapy (8) and chemotherapy (6). Fourteen tumors were monophasic and 1 was biphasic; 4 had poorly differentiated (PD) foci (1 rhabdoid). Diagnoses in 12 cases were verified by fluorescence in situ hybridization, reverse transcription polymerase chain reaction or both methods. Follow-up in 14 patients (median, 32 mo) revealed that 2/4 patients with PD tumors died with pulmonary metastases; another was alive with no current evidence of disease (NED) following 2 local recurrences, while the fourth had NED. In contrast, 9/10 patients without PD tumors were alive (7 NED) and 1 died at 12 months with pulmonary infiltrates. SSPN is under-recognized clinically and histologically as it mimics benign and malignant PNST. Molecular analysis is recommended to confirm the diagnosis. PD foci, including rhabdoid areas, may portend a worse outcome, similar to non-neural-based tumors.

Abstract
Angiosarcoma is a rare vascular malignant neoplasm that mainly occurs in skin and soft tissues. Intracranial localization is very rare and only a few cases have been reported. This report intends to present the clinical, radiological and pathological pictures of a primary central nervous system angiosarcoma along with a review of the literature. A 35-year-old woman presented at our institution with weakness and sensory disturbances of her right hand. Neuroimaging revealed a roughly round, hemorrhagic and moderately enhancing lesion in the left frontal posterior region. The tumor was totally removed under awake anesthesia and continuous monitoring of motor and language functions. Histopathology revealed an epithelioid angiosarcoma. Radical removal, followed by adjuvant radiotherapy and chemotherapy, is able to completely control the disease for a relatively long period.

Abstract
Tumors of peripheral nerve origin are usually slow growing and minimally symptomatic, making differentiation from other soft tissue neoplasms difficult. Yet failure to recognize a nerve tumor may result in irreversible loss of neurologic function. This article provides current information on the history, pathologic identification, and treatment of upper extremity nerve tumors. Other neoplastic and tumor-like lesions that occur within the peripheral nerve are also considered.

Abstract
AIMS Angiosarcomatous differentiation represents the least common form of heterologous differentiation in malignant peripheral nerve sheath tumours (MPNST), and is seen most frequently in patients with neurofibromatosis type 1. More rarely, it has been reported in patients without stigmata of neurofibromatosis, or in benign nerve sheath tumours and peripheral nerves. This study was undertaken to confirm this rare association. METHODS AND RESULTS Four cases of angiosarcoma arising in a peripheral nerve, in a long-standing schwannoma and in two MPNST are described. Immunohistochemical studies were performed on paraffin sections with the alkaline phosphatase-antialkaline phosphatase method. An intraneural high-grade epithelioid angiosarcoma arose in the left posterior tibial nerve of a 78-year-old man, a well to moderately differentiated angiosarcoma was seen in an ancient schwannoma of the lateral neck in a 73-year-old women, and an angiosarcoma of varying grades of differentiation developed in a recurrent MPNST in the thigh of 38-year-old man. In addition a high-grade MPNST in the axillary region of a 30-year-old man showed foci of heterologous high-grade angiosarcomatous differentiation. The neural and endothelial lines of differentiation were confirmed in each case by positive immunohistochemical staining for neural and endothelial markers, respectively. In all cases tested, the neural differentiated cells stained immunohistochemically positive for antibodies against vascular endothelial growth factor. CONCLUSIONS This study confirms the rare association of angiosarcoma arising in peripheral nerves, as well as in benign and malignant peripheral nerve sheath tumours.

Abstract
Angiosarcomas rarely develop within a peripheral nerve or a peripheral nerve sheath tumor. We describe an epithelioid angiosarcoma that arose in a benign schwannoma (neurilemoma) of the right thigh in a 65-year-old man who did not have von Recklinghausen's disease. Histologically, the resected tumor was a high-grade undifferentiated sarcoma that was predominantly arranged in solid sheets or nests and composed of epithelioid cells. The endothelial origin of the tumor was suggested by Factor VIII R-ag, Ulex europaeus-I, CD34, CD31, BNH9, and vimentin immunoreactivity, along with the ultrastructural evidence of occasional Weibel-Palade bodies. In this location, epithelioid angiosarcoma should be distinguished from malignant transformation of a schwannoma with epithelioid changes. This observation stresses the importance of immunohistochemical and ultrastructural analysis in the differential diagnosis of vascular tumors with features of epithelioid sarcoma.

Abstract
Angiosarcoma arising in the central or peripheral nervous system has rarely been reported. Eight patients with primary angiosarcoma of the central nervous system are described here; these included five males and three females ranging in age from 2 weeks to 72 years (mean 38 years). Of the eight neoplasms, six were located in the cerebral hemispheres and one was in the meninges; the site was unknown in the other. All patients underwent surgical resection. Five of the eight patients died, four within 4 months after surgery and one after 30 months. Two of the remaining three patients were 17 and 27 years old at the time of diagnosis and were alive at follow-up review 39 and 102 months after surgery, respectively. One patient was lost to follow-up monitoring. Microscopically, all eight tumors demonstrated a well-differentiated pattern with irregular vascular channels and intraluminal papillae; in addition, four showed poorly differentiated solid areas. Immunohistochemical staining of neoplastic cells to factor VIII-related antigen and Ulex europaeus agglutinin I was performed in five tumors and was focally positive in four. No correlation could be shown between the histological features and the growth and biological behavior of the tumors.

Abstract
The authors report the case of a hemangiopericytoma arising in a sciatic nerve. It was found to be invasive within the epineurium but sparing surrounding tissues. Adequate resection required sacrifice of the nerve. Hemangiopericytomas can be added to the short list of mesodermal peripheral-nerve tumors.

Abstract
A 65-year-old man with a history of exposure to industrial solvents developed a primary cerebral angiosarcoma in the left posterior parieto-occipital lobe. The tumor had features typical of angiosarcoma on light and electron microscopy, immunohistochemical evidence of factor VIII-related antigen produced in tumor cells, and a high labeling index with bromodeoxyuridine. The relationship of angiosarcoma to toxins and viruses is discussed.

Abstract
A male aged 60 is reported who, 5 years after chordotomy at the Th 2/3 level, developed acute paraplegia of the legs and a sensory transverse lesion due to an extradural tumour of the Th 1-4 level. Neuropathology revealed transverse necrosis of the thoracic spinal cord (Th 1-4) due to an intradural tumour at the upper thoracic and lumbar spinal levels, the thoracic malignancy arising at the site of the previous chordotomy, with a suture being observed within the tumour mass. Histology, positive immunostaining of tumour cells with Factor VIII antigen, a specific marker of endothelial cells and the ultrastructural demonstration of Weibel-Palade bodies in endothelial cells of the tumour vessels suggested a malignant mesenchymal tumour of angiosarcoma type presumably arising from the spinal meninges, and broadly invading the spinal cord. The usual relation of this extremely rare intraspinal vasoformative malignancy to previous chordotomy is discussed.

Abstract
An autopsy case of malignant schwannoma in a 31-year-old female associated with von Recklinghausen's disease with unusual elements is reported. The patient who was diagnosed as von Recklinghausen's disease from a biopsy specimen of a subcutaneous tumor in her shoulder and multiple café au lait spots in her chest and back, complained of gradual increase in pain in her lower abdomen. A large mass measuring about 18 cm in diameter was located in her left retroperitoneum. Malignant schwannoma associated with von Recklinghausen's disease was indicated by the cellularity of the tumor, intersecting bundles of spindle cells, alternating cellular and less cellular myxoid areas in the peripheral portion of the tumor, whereas a large part of the tumor had a hemangiopericytoma-like arrangement with gaping blood vessels. In addition, however, foci of rhabdomyosarcomatous differentiation and of angiosarcomatous components were found in some areas of this tumor. Moreover, intravascular schwannian growth, which was presumably related to von Recklinghausen's disease, was observed in the heart and thyroid. This tumor should be classified as a malignant triton tumor because of the presence of rhabdomyoblasts.

Abstract
A patient with Von Recklinghausen neurofibromatosis and an angiosarcoma (which developed subsequent to two separate neurofibrosarcomas ) is described, and the association of neurofibromatosis and angiosarcoma is reviewed. The data showed that angiosarcoma is not coincidental with neurofibromatosis, and there is a need to focus investigative efforts on the vascular aspects of this disease.

Abstract
The first reported case of an angiosarcoma apparently arising from the superior vena cava is presented. The patient, a 20-year-old white man, was treated by surgical excision and reconstruction with dacron grafts from the left and right brachiocephalic veins to the right atrium. This was followed by a course of mediastinal irradiation. The patient remained clinically disease-free at 24 months post-treatment. The patient had occasional occupational exposure to polyvinyl chloride.

Abstract
The authors present an angiosarcoma of the scrotum and penis. The disease occurred in a 61-year-old man with a long history of neurofibromatosis (von Recklinghausen's disease). The histologic and ultrastructural features are described. The authors speculate that the angiosarcoma, which developed in a location without histologic evidence of neurofibromatosis, possibly represents an expression of an abnormal genome in vascular tissue. The angiosarcoma responded to radiation therapy only temporarily, recurred after surgery, and did not respond to Adriamycin, dactinomycin or cis-platinum. The patient died three years after the onset of his angiosarcoma.

Abstract
The following is a description of the diagnostic structural features in three neoplasms in which we diagnosed: primary intraparenchymal brain sarcoma. One appeared to have arisen de novo from the mesenchymal components of the brain parenchyma and was labeled fibrosarcoma. A second case, having mixed features of meningioma and fibrosarcoma, may represent an instance of sarcomatous changes in a prexisting intraparenchymal meningioma. The third sarcoma's ultrastructural characteristics were those of embryonal capillaries and a designation of hemangiosarcoma is proposed for that one. An angiographic, preoperative diagnosis of meningioma was suggested in all three instances. Two of the patients died a few weeks after craniotomy and the third one is alive and well eighteen months after resection of the neoplasm.
