Cytological features of uterine tumors resembling ovarian sex‐cord tumors in liquid‐based cervical cytology: a potential pitfall. Report of a unique and rare case

Uterine tumors resembling ovarian sex‐cord tumors (UTROSCTs) are rare uterine neoplasms of uncertain etiology that resemble the sex cord tumors of the ovary and display a combined sex cord, epithelial, and smooth muscle immunophenotype. Most tumors are associated with a benign clinical course. We report the first cytological description of uterine UTROSCTs in liquid‐based cervical cytology (LBC). A menopausal woman was discovered to have a uterine intraluminal polypoid mass protruding through the vagina. A Pap test was performed, and the LBC preparation showed isolated tumor cells with scant cytoplasm and slightly irregular, ovoid nuclei with fine chromatin and small nucleoli. Final histological evaluation identified a UTROSCT. This diagnostic possibility, albeit rare, should be included in the differential diagnosis when isolated malignant‐appearing adenocarcinomatous cells are seen in women in the above scenario. As these features are not specific, they may result in misinterpretation with tumors that are more common and aggressive.
