2014 WHO classification of endometrial stromal tumours

Dr Varun Babu et al.

Endometrial stromal tumours (EST) constitute <2% of all uterine tumours and <10% of uterine mesenchymal neoplasms 1

Over the past four decades, EST classification has gone through various modifications, starting from the earliest study by Norris and Taylor 2. This was primarily due to the rarity of the tumours. With better understanding, and at the time of writing (mid 2016), the 2014 WHO classification has replaced the broad categories of the 2003 WHO classification following incorporation of molecular findings. 


  1. Endometrial stromal nodule (ESN)

  2. Low-grade endometrial stromal sarcoma (LGESS)

  3. High-grade endometrial stromal sarcoma (HGESS)

  4. Undifferentiated uterine sarcoma (UUS)
