title: Low-grade endometrial stromal sarcoma of the ectocervix after therapy for breast cancer.
abstract: OBJECTIVE
  Low-grade endometrial stromal sarcoma is an uncommon, indolent uterine sarcoma that can arise in extrauterine locations. The objective of this study was to report on a previously unpublished site of origin for a low-grade endometrial stromal sarcoma.
  
  
  METHODS
  A case of a low-grade endometrial stromal sarcoma arising in the ectocervix after goserelin hormonal therapy for breast cancer was studied.
  
  
  RESULTS
  Low-grade endometrial stromal sarcoma can arise in the ectocervix even in the absence of endometriosis.
  
  
  CONCLUSIONS
  Low-grade endometrial stromal sarcoma should be included in the differential diagnosis of sarcomas of the ectocervix.
