Uterine Angiosarcoma: A Case Report and Literature Review.
2016
Uterine
angiosarcomais a rare, extremely malignant vascular tumor. Here, we report a case of giant uterine
angiosarcomain a 56-yr-old woman. The tumor was diagnosed as an epithelioid uterine
angiosarcomabased on histopathologic findings. The tumor cells showed vascular differentiation; they were positive for the vascular endothelial markers
CD31, CD34, and was negative for lymphatic endothelial marker D2-40. In addition, the tumor cells showed overexpression of cell-cycle regulatory protein
cyclin D1and were positive for
epithelial-mesenchymal transitionmarker
vimentin. Although it was reported previously that there was
breakagein
YWHAE, NUTM2A (FAM22A), and NUTM2B (FAM22B) in a case of uterine
angiosarcoma, no
breakagein these loci was detected by
fluorescencein
situ hybridizationin the present case.
