Adult ovarian granulosa cell tumor with high-grade hepatoid transformation: Case report and review of literature.
Adult Granulosa Cell Tumors (AGCTs) are uncommon ovarian neoplasms typically characterized by low-grade malignant behavior. However, AGCTs can occasionally undergo high-grade transformation, which may substantially impact clinical outcomes. In this study, we report the first documented instance of AGCT with high-grade hepatoid transformation (AGCT-HGHT) and perform a review of previously reported cases of AGCT with high-grade/sarcomatoid transformation (AGCT-HST). This case expands the spectrum of AGCT-HST and ovarian tumors with hepatoid morphology and emphasizes the need for further research into the molecular mechanisms and clinical significance of these genetic alterations as potential prognostic markers and therapeutic targets in AGCTs.
