Background: Endometrial stromal carcinoma (ESS) is characterized by proliferation of blood vessels and comparatively uniform tumor cells resembling the stromal cells in proliferative endometrium. We performed a cytomorphologic study of imprinted materials of three histologically confirmed ESS (1 low grade, 2 high grade).
Cases: In addition to previously reported features, all three cytologic specimens showed characteristic vascular features; fine vascular structures surrounded by tumor cells. This cytologic feature would reflect the histological concentric proliferation of blood vessels and tumor cells surrounding the vessels.
Conclusion: This vascular finding in cytology will prove to be useful for discriminating ESS from uterine leiomyomas and other tumors when included with the conventional cytomorphological features of the ESS.
