A case of multifocal angiosarcoma of the small intestine is reported. These tumors often contain areas of solid sheets of cells and may be confused with poorly differentiated carcinoma or other sarcomas, as was the tumor in the reported case. Factor VIII-related antigen was demonstrated in biopsy samples by the peroxidase antiperoxidase method, showing the tumor to be an angiosarcoma. We conclude that the demonstration of factor VIII-related antigen in the neoplastic cells is an important aid in the diagnosis of angiosarcoma.
报告了一例小肠多灶性血管肉瘤。这些肿瘤通常含有实性细胞片区域，可能会与低分化癌或其他肉瘤混淆，报告病例中的肿瘤就是如此。通过过氧化物酶抗过氧化物酶方法在活检样本中证实了VIII因子相关抗原，表明该肿瘤为血管肉瘤。我们得出结论，肿瘤细胞中VIII因子相关抗原的证实对血管肉瘤的诊断有重要帮助。
