title: Malignant potential of endometrial stromal tumor with limited infiltration: a case report.
abstract: 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.
