INTRODUCTION: We present the rare case of a 29-year-old patient with uterine adenosarcoma who received fertility-sparing treatment, subsequently conceived spontaneously, and gave birth to a healthy infant.
CASE: In August 2022, the nulliparous patient presented with acyclic uterine bleeding. Diagnostic hysteroscopy and targeted resection of a polyp located at the cervicouterine junction revealed uterine adenosarcoma without sarcomatous overgrowth (FIGO stage T1a). Imaging confirmed no residual tumor or metastasis. A fertility-sparing management strategy was chosen, avoiding hysterectomy but involving close oncological surveillance with quarterly MRI scans. During follow-up, a concurrent diagnosis of symptomatic endometriosis introduced therapeutic challenges. The patient spontaneously conceived in 2023 and delivered a healthy infant by cesarean section at term in 2024. Subsequent hysteroscopy and imaging in 2025 showed no evidence of recurrence, therefore fertility-preserving management was continued.
PATIENT PERSPECTIVE: A short narrative of the patient's perspective on her initial diagnosis, possible fertility loss, and the emotional turmoil of pregnancy after uterine adenosarcoma is presented.
DISCUSSION: Treating young patients diagnosed with uterine adenosarcoma poses a challenge to the treating physician due to the lack of guidelines and evidence regarding fertility-preserving treatment of this rare tumor. This report adds to the limited literature on successful pregnancy after uterine adenosarcoma and discusses indications and limitations of fertility-sparing treatment.
CONCLUSION: Fertility preservation may be possible in selected early-stage uterine adenosarcoma cases without high-risk features such as sarcomatous overgrowth or myometrial invasion, with thorough counseling and strict follow-up. Further research is needed to develop standardized protocols and improve management in this context.
