这一例很有意思,少见,有点难,发不起言,谢谢楼主分享。
想到过侵袭性血管粘液瘤或浅表性血管粘液瘤,但是想不起准确的病名了,只想到了同一篇文章中的血管肌纤维母细胞瘤。也记不起是那本杂志上看过的了,也没法查。知道血管肌纤维母细胞瘤可能性不大,说这个诊断意在抛砖引玉。本例还要鉴别的是恶性纤维组织细胞瘤,粘液性脂肪肉瘤,粘液性平滑肌肉瘤等。
血管肌纤维母细胞瘤,血管较丰富,肿瘤细胞围血管生长。本例不太像。
从大体来看有包膜,比较支持浅表性血管粘液瘤。但是近期生长快,更支持侵袭性血管粘液瘤。
希望听到专家分析。
Differential dx includes aggressive angiomyxoma and angiofibroblastoma. One of the important features favoring angiofibroblastoma is relatively circumscribed boarder. Angiofibroblastoma can also be more cellular than aggressive angiomyxoma. Immunostaining is not too helpful in this setting although aggressive angiomyxoma tends to have PR positivity. Since the tumor is out now, the most important part for pathologist is to make sure the resection margin is negative for this neoplasm.
