目的 加深对子宫内膜间质肿瘤病理形态的认识。方法 对 1例间质结节、1 5例低度恶性及 3例高度恶性间质肉瘤进行临床病理分析。结果 肉瘤组中 4例以粘膜下肿物为主要表现 ,4例手术后复发。病理检查 4例有宫外病灶 ,6例伴有性索样分化 ,7例有明显的平滑肌分化。结论 低度恶性间质肉瘤是子宫内膜间质肿瘤的主要表现形式 ,性索样分化与平滑肌分化在间质肿瘤中不少见。
Objective To deepen the understanding of the pathological morphology of endometrial stromal tumors. Methods One case of mesenchymal nodules, 15 cases of low grade malignant and 3 cases of high grade malignant mesenchymal sarcoma were analyzed clinically and pathologically. Results In the sarcoma group, 4 cases were mainly submucosal tumor, and 4 cases were recurrence after operation. Pathological examination in 4 cases of extrauterine lesions, 6 cases associated with cord-like differentiation, 7 cases of significant smooth muscle differentiation. Conclusions Low grade malignant mesenchymal sarcoma is the main form of endometrial stromal tumors. Sexual cordlike differentiation and smooth muscle differentiation are not uncommon in stromal tumors.
