本症是由Masson氏于1928年首先描述的一种特殊的血管内皮细胞增生病变。开始被一些病理工作者误诊为血管内皮肉瘤、Kaposi氏肉瘤、不典型性血管瘤等;后来证明是一种良性瘤样病变。至今命名很不一致:如血管内乳头状内皮细胞增生、Masson氏赘生性血管内皮细胞瘤,Masson氏假性血管肉瘤,血管内血管瘤病等。现将我科发现的两例作一报导。 This disease is a special vascular endothelial cell proliferative lesion first described by Masson’s in 1928. Some pathologists were misdiagnosed as vascular endothelial sarcoma, Kaposi’s sarcoma, atypical hemangiomas, etc.; later it turned out to be a benign tumor-like lesion. So far, the naming has been very inconsistent: such as intravascular papillary endothelial cell proliferation, Masson’s neoplastic vascular endothelial cell tumor, Masson’s pseudoangiosarcoma, and intravascular angiomatosis. Two cases have been reported in our department.
