A case of low-grade endometrial stromal sarcoma with multiple metastasis / 대한산부인과학회지

Uterine sarcomas are rare tumors of mesodermal origin and constitute 2-6% of uterine malignancies. They are classified into leiomyosarcoma (LMS), malignant mixed mullerian tumors (MMMTs), and endometrial stromal sarcoma (ESS) by histologic types. Endometrial stromal sarcomas account for about 7-15% of uterine sarcomas, about 0.2% of female genital tract malignancies. Endometrial stromal sarcomas are divided into endometrial stromal nodule, low-grade endometrial stromal sarcoma, and high-grade endometrial stromal sarcoma on the basis of mitotic activity and vascular invasion. Clinical outcome of low-grade endometrial sarcoma is better than that of high-grade endometrial stromal sarcoma and has a propensity for slow metastasis. We have experienced a case of low-grade endometrial stromal sarcoma with multiple metastasis in a 41-year-old woman and was treated by surgical resection and combination chemotherapy, which is presented with a review of brief literature.

3 Cases of Low-grade Endometrial Stromal Sarcoma / 대한산부인과학회잡지

Endometrial stromal sarcomas (ESS) of the myometrium compose just 0.2% of uterine malignant tumors. In terms of their cellular mitotic activities, they are named as low grade or high grade ESS. As low grade ESS are very rare, we would like to report our 3 cases with immunohistochemical stain method, treatment option as the disease progression and the brief review of literature.
