1/1048. Human herpes-virus 8 seropositive patient with skin and graft Kaposi's sarcoma after lung transplantation.

    Kaposi's sarcoma (KS) has been reported after solid organ transplantation mostly in recipients of renal, liver, heart, and bone allografts. We describe the first case of a patient with lung transplantation who developed KS of the skin, but also of the lung graft. The tumors were localized to places of previous trauma, implying the involvement of a Koebner phenomenon. Moreover, a polymerase chain reaction assay revealed the presence of dna sequences of herpesvirus 8 (HHV-8) on tissue of the cutaneous KS. Serological tests showed HHV-8 seronegativity of the graft donor and HHV-8 seropositivity of the patient before lung transplantation suggesting that the latter was already infected before the surgery and that immunosuppression resulted in the development of KS. This case report raises the question of the prevalence of HHV-8 in candidates for transplantation and organ donors, and of the value of an antiviral prophylaxis to lower the risk of KS.

2/1048. Ewing's sarcoma of os calcis: case report with a review of literature.

    A rare case of Ewing's sarcoma of os calcis is described here. Its atypical clinical and radiological features often delay the diagnosis. These features and review of literature are discussed.

3/1048. Acral dermatofibrosarcoma protuberans with metastases.

    dermatofibrosarcoma protuberans (DFSP) is an uncommon cutaneous tumor that occurs rarely on the extremities. This tumor has a particular propensity for local recurrence following seemingly adequate excision. Metastases are rare, and usually follow repeated local recurrences. On rare occasions, fibrosarcomatous change may arise in a DFSP, and appears to affect adversely the prognosis. The adequacy of the initial resection is the most important prognostic factor; however, suggested margins vary between 1.5 and 5 cm. The ideal margin of resection on the foot is unknown. We report a patient with recurrent, acral DFSP with fibrosarcomatous change and pulmonary parenchymal metastases in a 48-year-old black male.

4/1048. Synovial sarcoma in the parapharyngeal space: case report and review of the literature.

    We encountered a rare case of synovial sarcoma in the parapharynx of a 47-year-old Japanese man. This patient presented with an enlarging tumor in the right side of his neck that had grown progressively over a 4-week period. Radiological examinations revealed that the tumor arose from the parapharyngeal space. The tumor could not be completely removed at surgery. Metastasis to the lumbar vertebra was detected postoperatively. The patient underwent three courses of chemotherapy and the delivery of palliative radiation to the lumbar vertebra without success. The patient died of lung metastasis 7 months after surgery.

5/1048. Extraneural metastasizing ependymoma of the spinal cord.

    This paper reports a case of the rare entity of an extraneural metastasizing ependymoma of the spinal cord. The tumor which arose in the conus medullaris and in the cauda equina was first diagnosed in 1956 when a thoracolumbar myeloresection was performed. At autopsy, 40 years after the primary diagnosis, a massive local tumor recurrence with extraneural metastases in the lungs, the pleura, the liver, and the thoracal and abdominal lymph nodes were found. Immunohistochemical stains of the extraneural metastases showed a strong cytoplasmatic expression of glial fibrillary acidic protein (GFAP). Neither the primary tumor nor its metastases showed any of the conventional morphological criteria of malignancy. Reviewing the literature we discuss the possible mechanism of extraneural tumor spread and the incidence of metastases with regard to the tumor type.

6/1048. Ocular adnexal granulocytic sarcoma as the first sign of acute myelogenous leukemia relapse.

    PURPOSE: To report a case of granulocytic sarcoma involving the eyelids and caruncles after bone marrow transplantation. methods: Case report. A 30-year-old man with acute myeloid leukemia in remission developed multiple friable eyelid and caruncular lesions in addition to two cutaneous lesions on the chest wall and right axilla approximately 3 months after a successful autologous bone marrow transplant. RESULT: Pathologic examination was consistent with granulocytic sarcoma. CONCLUSION: This condition should be considered in the differential diagnosis of cutaneous or eyelid masses in patients with a history of leukemia.

7/1048. Epstein-Barr virus-associated leiomyosarcoma of the thyroid in a child with congenital immunodeficiency: a case report.

    We report an unusual case of multifocal leiomyosarcoma involving the thyroid gland, liver, and right lung in a child with congenital immunodeficiency disease. The smooth muscle nature of these neoplasms was confirmed by immunohistochemistry and electron microscopic studies. in situ hybridization showed large amounts of Epstein-Barr virus messenger rna within the tumor cells. Although Epstein-Barr virus-associated smooth muscle tumors have been reported in children with AIDS and after organ transplantation, we are unaware of any case report in congenital immunodeficiency disease.

8/1048. Angiosarcoma of the chest wall.

    Angiosarcoma is a rare and highly malignant tumor of vascular origin. The causative factors include trauma, radiation, foreign bodies, thorium dioxide, and viral infections. We report a case of angiosarcoma occurring in a thoracotomy incision 17 years after operation for stage I lung cancer.

9/1048. Primary synovial sarcoma of the lung: report of two cases confirmed by molecular detection of SYT-SSX fusion gene transcripts.

    AIMS: Primary pulmonary sarcoma is rare, and frequently creates diagnostic challenges. We describe two cases of primary pulmonary spindle cell sarcoma in which a molecular approach using archival paraffin-embedded tissue was proved to aid diagnosis. methods AND RESULTS: Both patients had huge masses replacing the upper and middle lobes of the lung, respectively, without any primary extrapulmonary neoplastic lesions. Microscopically, the lesions showed a solid hypercellular nodular or lobular growth of atypical short spindle cells in variably intersecting fascicles or in a haphazard fashion, together with focal areas displaying a prominent haemangiopericytoma-like pattern. Immunohistochemically, a small number of the tumour cells were positive for epithelial markers such as cytokeratin and epithelial membrane antigen. In both cases, a reverse transcription-polymerase chain reaction using rna extracted from formalin-fixed, paraffin-embedded tissues detected SYT-SSX fusion gene transcripts, which are characteristic of synovial sarcoma. CONCLUSION: On the basis of the morphological and molecular findings, these tumours are considered to be rare examples of monophasic synovial sarcoma of the lung. Our molecular assay detecting the SYT-SSX fusion transcripts is useful for the final diagnosis of synovial sarcoma arising at such an unusual anatomical site.

10/1048. October 1998--61 year old male with brain tumor and oral, lung, and palpebral masses.

    In Jan. 97 a gliosarcoma was diagnosed in a 61-year- old man after a 6-month history with neurological deficits. A total physical examination, laboratory tests, chest x-ray and abdominal ultrasound scanning revealed no gross abnormalities. Surgery was followed by brain radiation therapy and 6 months later there were metastases to the oral cavity, right palpebra and both lungs. The histological findings of the oral and palpebral metastases revealed only the sarcomatous component. We are aware of 15 cases of gliosarcoma with extraneural metastases, and in 4 of these, the metastases contained only the sarcomatous component. We believe that our case represents the fifth case of pure sarcomatous metastases.
