We report the case of a 79-year-old woman with a large pelvic mass and postmenopausal bleeding, associated with hyperestrogenism. A pelvic MRI shows the presence of a large mass of 12.6 cm originating from the right ovary without signs of metastasis. A total abdominal hysterectomy with unilateral salpingooophorectomy was performed, knowing the patient underwent a left salpingooophorectomy decades ago. The pathological findings showed an ovarian clear cell carcinoma (pT1A) with associated endometrial intraepithelial neoplasia. There is convincing evidence that the production of estrogen is located in the activated ovarian stroma. This supports the view that functioning stroma of ovarian cancer can lead to hyperestrogenism and eventually endometrial cancer.

Background: Ovarian cancer is a prevalent and highly lethal gynaecological cancer. Among its various subtypes, epithelial ovarian cancer predominates, comprising of ten distinct subtypes and contributing significantly to the overall burden of ovarian malignancies. Concurrently, endometriosis, characterised by the ectopic growth of endometrial tissue within the pelvis, affects a substantial number of women of reproductive age.

Introduction: Ovarian clear cell carcinoma (OCCC) accounts for about 5% of all epithelial ovarian cancers. Currently, its treatment mainly refers to high-grade serous carci-noma (HGSC). This study aimed to explore differences in clinical characteristics between OCCC and HGSC and studied the reasons for the differences.

Background: Clear cell carcinoma occurring outside of the kidney represents an aggressive histological subtype which is frequently resistant to standard chemotherapy. Brain metastases (BM) from extra-renal clear cell carcinoma (erCCC) are exceedingly rare, and the optimal treatment approach for this histology remains uncertain. To our knowledge, stereotactic radiosurgery (SRS) has not been specifically investigated for this patient population.

Study Question: What is the diagnostic yield and the pre-testicular sperm extraction (TESE) prognostic value of a non-obstructive azoospermia (NOA)-specific virtual gene panel?
Summary Answer: The diagnostic yield in our cohort was 6.1%, and by combining our data with published literature, we identified 11 genes compatible with testicular sperm production and 19 genes associated with no sperm retrieval in carriers of pathogenic (P) or likely pathogenic (LP) mutations.
What Is Known Already: Azoospermia, the most severe form of male infertility, affects ∼1% of the male population, with TESE being the primary treatment option.

Background: The dynamic interplay of ovarian hormones is central to reproductive physiology, yet the complexity of their cyclic variations poses challenges for analysis, simulation, and teaching. This study presents a framework for generating physiologically constrained, multi-hormone synthetic time series that capture intra- and inter-individual variability across phenotypes.
Methods: We developed a semi-mechanistic mathematical framework to generate synthetic multi-hormone profiles (estradiol, FSH, LH, AMH, testosterone, GnRH) using parametric equations embedding known physiological feedbacks (e.
