Two Cases of Low-Grade Endometrial Stromal Sarcoma / 대한산부인과학회잡지

ABSTRACT

Endometrial stromal sarcomas are rare uterine tumors accounting for about 0.2% of female genital tract malignancies, which are composed of cells closely resembling normal proliferative endometrial stromal cells. The tumor is classified into a low-grade and a high-grade variety on the basis of the mitotic rate. The low- grade endometrial stromal sarcoma has many synonyms, which include endolymphatic stromal myosis, stromatosis, stromal endometriosis and endometrioid sarcoma. Because the endometrial stromal sarcoma is very rare, the preoperative diagnosis and postoperative treatment are still difficult for clinicians. We have experienced two cases of low-grade endometrial stromal sarcoma of the uterus which are presented with a review of brief literature.
