Premature ovarian insufficiency (POI) is a clinical syndrome characterized by ovarian failure in women of reproductive age before the age of 40 years. Its main manifestations include menstrual cycle disturbances, such as oligomenorrhea or amenorrhea. The etiology of POI is highly heterogeneous, with a particular emphasis on genetic and immunological factors. In addition, the condition may be associated with other rare diseases, such as Vogt-Koyanagi-Harada (VKH) syndrome. Our study aimed to describe a rare clinical case of a patient from Manaus, Amazonas, Brazil, who was simultaneously diagnosed with two rare conditions: POI and VKH syndrome, with a specific focus on their etiological characteristics, clinical manifestations, and laboratory findings. Clinical data were collected from the patient's medical record, as registered in the outpatient clinic database at Araújo Lima Hospital. Case description: The case involves a 38-year-old, nulliparous, mixed-race, married female patient diagnosed with POI and VKH syndrome. The understanding of these rare syndromes and the search for an integrated approach are fundamental to ensure better clinical outcomes, quality of life, and reproductive planning for affected patients. This report provides relevant information on the association between two rare syndromes, with the aim of contributing to medical decision-making and diagnostic clarification, as well as providing guidance on appropriate multidisciplinary follow-up. Thus, early diagnosis and appropriate treatment are essential steps in promoting this patient's health.

Blepharophimosis, ptosis, and epicanthus inversus syndrome (BPES) is an eyelid malformation present at birth in all individuals involving, respectively, narrowing of the horizontal aperture of the eyelids, drooping of the upper eyelid, a skin fold arising from the lower eyelid and running inward and upward, and lateral displacement of the medial canthi. Other ocular findings that occur at increased rates compared to those in the general population include strabismus, refractive errors, and amblyopia. The second finding is age-related primary ovarian insufficiency (POI) in affected females characterized by reduced penetrance as well as interfamilial and intrafamilial variability. A minority of affected women experience primary amenorrhea (i.e., the absence of menarche by age 15 years due to ovarian dysfunction). Menarche is usually normal, followed by oligomenorrhea and secondary amenorrhea for at least four months. Secondary sexual characteristics are usually normal.

MCM8/MCM9-related syndromes are characterized by primary gonadal insufficiency (hypergonadotropic hypogonadism) and increased risk of early-onset germ cell tumors in females. Hypergonadotropic hypogonadism can present in females as primary amenorrhea, secondary amenorrhea/oligomenorrhea, underdeveloped uterus, or small/streak ovaries, and in males as impaired spermatogenesis (nonobstructive azoospermia, oligospermia, or Sertoli cell-only syndrome); incomplete or delayed pubertal development is more often seen in females. MCM9-related syndrome is also associated with increased susceptibility to colorectal polyposis (adenomas, hyperplastic or sessile serrated polyps), early-onset colorectal cancer (CRC), and early-onset gastric cancer.

BACKGROUND: Polycystic Ovary Syndrome (PCOS), Premature Ovarian Failure (POF)(menopause before age 40), and Endometriosis (EMs) are major challenges; early detection is vital for effective management, improved outcomes, and sustained health support for women. We aimed to characterize patients with POF, EMs, and PCOS in women attending comprehensive health centers in Urmia, Iran. METHODS: This health center-based study involved 373 women. Medical findings obtained from transvaginal sonography, along with clinical features, signs, symptoms, and biochemical analyses were employed to characterize the women with PCOS, POF, and EMs. RESULTS: The frequency of PCOS, POF, and EMs in the tested population were 17.69%, 0.8%, and 3.5%, respectively. Notable differences were identified among women with PCOS compared to healthy individuals regarding alcohol consumption, the place of residence, menstrual cramps, scale of dysmenorrhea-related pain, menstrual cycle, feeling of an abdominal mass, menstrual back pain, abortion, constipation, amenorrhea, hypomenorrhea, oligomenorrhea, ovarian cyst, abnormal pap smear, vaginal infection, diabetes, hormone therapy, primary infertility, acanthosis, acne, hirsutism, and alopecia. Severe dysmenorrhea-related pain and the sensation of an abdominal mass are key characteristics for effectively screening women with POF. Informative clinical characteristics for EMs include dysmenorrhea, severe dysmenorrhea-related pain, heavy menstrual bleeding, abdominal mass feeling, chronic pelvic discomfort, menstrual back pain, oligomenorrhea, ovarian cysts, primary infertility, acanthosis, and acne. CONCLUSIONS: The majority of women diagnosed with PCOS lived in rural areas. Healthcare systems should place a high priority on women’s health in rural regions, where scarce resources and accessibility issues frequently undermine well-being. It is crucial to emphasize early detection, reproductive health, mental wellness, and social support. Enhancing these services not only improves the quality of life for women but also fortifies community resilience and guarantees fair health opportunities for all rural inhabitants, both now and for future generations to prosper.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder among women of reproductive age. It is clinically characterized by a group of symptoms, including oligomenorrhea or amenorrhea, hyperandrogenism, and the presence of ovarian cysts. Recently, the ovarian stromal microenvironment has emerged as a critical focus of investigation. This review begins by delineating the key components of the ovarian stromal microenvironment, such as stromal cells, extracellular matrix (ECM), vasculature, nerves, and immune cells, and their respective roles in maintaining ovarian homeostasis. Subsequently, it elaborates on the pathological alterations in PCOS, including fibrosis, inflammation, stromal hyperplasia, and aberrant angiogenesis, and discusses how these changes relate to the components of this microenvironment. Furthermore, we present several potential therapeutic strategies that target these aberrant processes. Examining PCOS through the lens of its stromal microenvironment provides deeper insights into its pathogenesis, thereby unveiling novel avenues for the development of targeted prevention and treatment strategies.
