Endometrial stromal sarcoma, abbreviated ESS, is a rare malignant mesenchymal tumour of the uterus.

It is also known as low-grade endometrial stromal sarcoma, abbreviated LGESS.

General

  • Uncommon.[1]
  • Prognosis good[2] > 90% five year survival and > 85% ten year survival.[3]

Note:

  • Extrauterine endometrial stromal sarcoma is known as endometrioid stromal sarcoma.[4]

Microscopic

Features:

  • Highly cellular islands with a wavy irregular border.
    • Border has finger-like projections/tongue-like projections.
    • Benign uterine smooth muscle between islands of tumour cells.
  • Epithelioid cells.
  • High NC ratio.
  • Thin blood vessels within islands of cells.
    • Tumour cells pallisade around the vessels.

Notes:

  • Vaguely resembles the stroma of proliferative endometrium.
  • Low mitotic rate - predictive of good outcome.[2]
