Endometrial stromal tumors (ESTs) with limited infiltration were first proposed by Dionigi et al.(1) However, the prognostic significance of these tumors is unclear. We report a case of a 60-year-old woman who presented with a prolapsed uterine corpus and then underwent laparoscopic-assisted vaginal hysterectomy. A very small EST was incidentally found. The tumor manifested focal irregularity and finger-like permeation into the adjacent myometrium not exceeding 3 mm but exceeding 3 in number, features intermediate between a low-grade endometrial stromal sarcoma and an endometrial stromal nodule. By definition, we rendered a descriptive diagnosis of "endometrial stromal tumor with limited infiltration." A subsequent staging operation confirmed metastasis and, hence, a malignant potential.
浸润有限的子宫内膜间质肿瘤（ESTs）最早由迪奥尼吉等人提出。(1) 然而，这些肿瘤的预后意义尚不清楚。我们报告一例60岁女性，她因子宫体脱垂就诊，随后接受了腹腔镜辅助阴道子宫切除术。术中偶然发现一个非常小的EST。肿瘤表现为局灶性不规则，呈指状浸润至相邻肌层，浸润深度不超过3mm，但数量超过3个，这些特征介于低级别子宫内膜间质肉瘤和子宫内膜间质结节之间。根据定义，我们做出了“浸润有限的子宫内膜间质肿瘤”的描述性诊断。随后的分期手术证实发生了转移，因此具有恶性潜能。
