A rare and atypical type of chorangioma is presented. The tumor was unusual in three aspects: (a) clinically, it was delivered after the placenta and required lavage; (b) grossly, the lesion was quite large; and (c) most importantly, it exhibited histologic features suggestive of sarcoma. Immunochemical staining of the tumor for factor VIII antigen demonstrated its endothelial origin. However, the tumor lacked evidence of invasion or biological aggressiveness. We propose that peculiar lesions of this type be termed "atypical cellular chorangiomas." No documented case of chorangiosarcoma could be identified in the literature.
本文报告了一种罕见的非典型性绒毛膜血管瘤。该肿瘤在三个方面表现异常：（a）临床上，它在胎盘娩出后出现，需要冲洗；（b）大体上，病变相当大；（c）最重要的是，它表现出提示肉瘤的组织学特征。肿瘤因子VIII抗原的免疫化学染色证实其起源于内皮。然而，该肿瘤缺乏侵袭或生物学侵袭性的证据。我们建议将这种特殊类型的病变称为“非典型细胞性绒毛膜血管瘤”。文献中未发现绒毛膜肉瘤的记录病例。
