It should also be emphasized that neoplastic endometrial stroma should not be found in the histological analysis of UTROSCT .
In a systematic review published in 2018 that evaluated prognostic factors of recurrence in UTROSCT, recurrence rates of 6.3% were found for the 79 patients evaluated.
Although there is currently no consensus with respect to the follow-up regimen for cases of UTROSCT, the patient in the present report is undergoing annual outpatient follow-up, with no signs of metastasis or tumor recurrence twelve months after surgery.
This is the first reported case of a UTROSCT in a prolapsed fibroid protruding into the vagina through the cervix.

(11,22) Furthermore, as described above, endometrial stromal tumors, including low-grade endometrial stromal sarcoma, endometrial stromal nodule, and ESTSCLE, show t(7; 17)(p15; q21) translocation; however, no specific or significant genetic alteration, including t(7; 17), is observed in UTROSCT. (17,18)
The neoplastic cells are invariably positive for smooth muscle actin, caldesmon, and CD99 in a more diffuse fashion, which may be observed in UTROSCT but to a lesser extent.
However, calretinin, inhibin, cytokeratin 7, and epithelial membrane antigen are negative, in contrast to UTROSCT. This tumor also has a benign behavior.
A UTROSCT is generally discovered only after hysterectomy, and most of the patients reported so far were managed with hysterectomy with or without bilateral salpingo-oophorectomy.
Uterine tumors resembling ovarian sex cord tumors (UTROSCT) lack the JAZF1-JJAZ1 translocation frequently seen in endometrial stromal tumors.
