Endometrial stromal sarcomas (ESS) are rare malignant tumors of the uterus. The primary tumour can occur in extra-uterine sites like ovary, fallopian tube, cervix, vulva, vagina, omentum and retro peritoneum. Primary low grade ESS occurring in ectocervix is reported very rarely. Primary tumour in the cervix mimics a fibroid polyp and poses a diagnostic dilemma.
We report a case of 43 years old perimenopausal lady who presented with bleeding
per vaginum and cervical polyp. Ultrasound revealed uterine leiomyoma in addition to the cervical polyp. Histological examination revealed epithelioid cell tumour. The diagnostic challenge was to differentiate ESS from epithelioid leiomyoma and PEcoma for which immunohistochemistry was carried out which showed positivity for
Cluster of Differentiation 10 (CD10), Estrogen Receptor (ER), Progesterone
Receptor (PR), Wilms’ Tumor 1 (WT1), Cytokeratin (CK) and Vimentin .
The case report emphasises the need to include ESS in the differential diagnosis of cervical polyp.
