Summary
We present the case of a 23-year-old patient with maturity-onset diabetes of the young type 3 (MODY 3) and premature ovarian insufficiency (POI). There is no known correlation between MODY 3 and POI, although POI can impair glucose metabolism, and MODY can cause microvascular complications such as POI. We did not find literature describing a correlation between these two pathologies nor did we find similar cases described in the literature.
Learning points
-
Maturity-onset diabetes of the young type 3 (MODY 3) is an infrequent cause of diabetes that should be considered in young patients with atypical presentation of type 1 or type 2 diabetes.
-
MODY 3 can be associated with microvascular complications of diabetes, which is why it is important to diagnose as early as possible.
-
Impairment of glucose metabolism has been demonstrated in patients with premature ovarian insufficiency and menopause.

Summary
Mayer–Rokitansky–Kuster–Hauser syndrome is characterized by congenital absence or hypoplasia of the uterus and upper two-thirds of the vagina in both phenotypically and karyotypically normal females with functional ovaries, whereas gonadal dysgenesis is a primary ovarian defect in otherwise normal 46,XX females. An association between these two conditions is extremely rare. We report a 21-year-old female presented with primary amenorrhea and undeveloped secondary sexual characteristics. The karyotype was 46,XX and the hormonal profile revealed hypothyroidism and hypogonadotropic hypogonadism. Pelvic MRI showed class I Mullerian duct anomaly with ovarian dysgenesis. Ultrasound showed bilateral thyroid hypoplasia and brain MRI suggested anterior pituitary hypoplasia. Levothyroxine and hormone replacement therapy were started.
Learning points
-
The simultaneous presentation of 46,XX gonadal dysgenesis, Mayer–Rokitansky–Kuster–Hauser syndrome, hypothyroidism, and pituitary hypoplasia is a Possibility.
-
Extensive evaluation should be made when a patient presents with one or more of these features.
-
The diagnosis imposes a significant psychological burden on patients and adequate counseling should be provided.
-
Hormone replacement therapy remains the only therapeutic option for the development of secondary sexual characteristics and the prevention of osteoporosis.

Summary
A 17-year-old lady presented with primary amenorrhoea, headache, nausea and lethargy. She had delayed pubertal development that also includes under-developed breast (Tanner Stage 2). Hormonal investigations showed a high serum prolactin level of 1 680 000 mIU/L (normal value: 45–375 mIU/L), with low oestradiol, progesterone, follicular-stimulating hormone and luteinizing hormone. Early morning cortisol level was 206 nmol/L (normal value: >450 nmol/L), thyroxine was 7.5 pmol/L (normal value: 9.0–24.0 pmol/L) with TSH 5.091 mIU/L (normal value: 0.4–4.5 mlU/L). A pituitary MRI showed a 2.7 (AP) × 3.7 (W) × 4.6 cm (CC) macroadenoma, with invasion into the left cavernous sinus and encasement of cavernous portion of the left internal carotid artery. MRI pelvis showed absent uterus, cervix and 2/3 upper vagina confirming Mullerian hypoplasia. Cytogenetics showed 46XX. These findings were suggestive of Mayer–Rokitansky–Kauser–Hauser (MRKH) syndrome with the presence of a pituitary macroprolactinoma and panhypopituitarism. She was treated with hydrocortisone, levothyroxine and cabergoline. Repeated MRI showed a reduction in tumour size by approximately 50%. This case illustrated a rare coexistence of these two conditions, being only the third reported case in the world. In addition, this would be the first case of a functioning pituitary adenoma in a patient with MRKH syndrome.
Learning points
-
Comprehensive hormonal and radiological investigations are important in the management of a young patient with primary amenorrhoea.
-
Coexistence pathology of two separate pathologies should be considered in patient presenting with primary amenorrhoea.
-
Early diagnosis of MRKH or any disorders of sex development should be treated early, providing pharmacological, surgical, psychological and emotional support to the patient and reducing risk of associated complications.
-
Abnormal pituitary hormones, particularly panhypopituitarism, would impose greater impact not only psychologically but also metabolically leading to cardiovascular, morbidity and mortality risks in this patient if not treated early.
-
A multidisciplinary approach is necessary for patients presenting with MRKH to ensure appropriate treatments and follow-up across the lifespan of the patient.

Summary
Polycystic ovarian syndrome (PCOS) is associated with menstrual irregularities, ovulatory dysfunction, hirsutism, insulin resistance, obesity and metabolic syndrome but is rarely associated with severe hyperandrogenaemia and virilisation resulting in male pattern baldness and clitoromegaly. Total serum testosterone greater than twice the upper limit of the reference range or free androgen index of over five-fold elevated suggests a diagnosis other than PCOS. We reported a case of a 15 years old obese girl presented with secondary amenorrhoea, virilising signs: frontal baldness, clitoromegaly and prominent signs of insulin resistance and marked acanthosis nigricans. Her total testosterone level was markedly elevated at 9.4 nmol/L (0.5–1.7 nmol/L) and MRI pelvis revealed a right ovarian mass with fat and cystic component and a left polycystic ovary. The patient underwent laparoscopic right ovarian cystectomy and histologically confirmed mature cystic teratoma. Post-operatively, her testosterone level declined but did not normalise, menses resumed but remained irregular. Her fasting insulin was elevated 85.2 mIU/L (3–25 mIU/L) and HOMA-IR was high at 13.1 (>2) with persistent acanthosis nigricans suggesting co-existing HAIR-AN syndrome, an extreme phenotype of polycystic ovarian syndrome.
Learning points:
-
Rapid onset of hyperandrogenic symptoms, especially if associated with signs of virilisation must raise the suspicion of an androgen-secreting tumour.
-
Total serum testosterone greater than twofold the upper limit of the reference range or free androgen indices over fivefold suggest a diagnosis other than polycystic ovarian syndrome (PCOS).
-
High levels of testosterone with normal levels of the DHEA-S suggest an ovarian source.
-
Ovarian androgen-secreting tumour and HAIR-AN syndrome, an extreme spectrum of PCOS can co-exist.

Summary
Menopause is a relative hyperandrogenic state but the development of hirsutism or virilizing features should not be regarded as normal. We report the case of a 62-year-old woman with a 9-month history of progressive frontotemporal hair loss and hirsutism, particularly on her back, arms and forearms. Blood tests showed increased total testosterone of 5.20 nmol/L that remained elevated after an overnight dexamethasone suppression test. Free Androgen Index was 13.1 and DHEAS was repeatedly normal. Imaging examinations to study adrenals and ovaries were negative. The biochemical profile and the absence of imaging in favor of an adrenal tumor made us consider the ovarian origin as the most likely hypothesis. After informed consent, bilateral salpingectomy-oophorectomy and total hysterectomy were performed. Gross pathology revealed ovaries of increased volume and histology showed bilateral ovarian stromal hyperplasia. Testosterone levels normalized after surgery and hirsutism had completely subsided 8 months later.
Learning points:
-
Menopause is a relative hyperandrogenic state
-
Hirsutism and/or virilizing features, in a postmenopausal woman, should raise the hypothesis of a malignant cause
-
In the absence of an identifiable ovarian or adrenal tumor, the ovarian origin remains the most likely
-
Peripheral aromatization of excess androgen may conduct to high levels of estrogen increasing the risk of endometrial cancer
-
Bilateral oophorectomy results in significant clinical improvement.

Summary
We describe a 56-year-old postmenopausal woman with hypertension, hypokalemia and severe alopecia who was found to have a 4.5-cm lipid-poor left adrenal mass on CT scan performed to evaluate her chronic right-sided abdominal pain. Hormonal studies revealed unequivocal evidence of primary aldosteronism and subclinical hypercortisolemia of adrenal origin. Although a laparoscopic left adrenalectomy rendered her normotensive, normokalemic and adrenal insufficient for 2.5 years, her alopecia did not improve and she later presented with facial hyperpigmentation acne, worsening hirsutism, clitoromegaly, and an estrogen receptor-positive breast cancer. Further testing demonstrated markedly elevated serum androstenedione and total and free testosterone and persistently undetectable DHEAS levels. As biochemical and radiologic studies ruled out primary adrenal malignancy and obvious ovarian neoplasms, a bilateral salpingo-oophorectomy was undertaken, which revealed bilateral ovarian hyperthecosis. This case highlights how the clinical manifestations associated with hyperaldosteronism and hypercortisolemia masqueraded the hyperandrogenic findings. It was only when her severe alopecia failed to improve after the resolution of hypercortisolism, hyperandrogenic manifestations worsened despite adrenal insufficiency and an estrogen receptor-positive breast cancer was found, did it becomes apparent that her symptoms were due to ovarian hyperthecosis.
Learning points:
-
As cortisol cosecretion appears to be highly prevalent in patients with primary aldosteronism, the term ‘Connshing’ syndrome has been suggested.
-
The associated subclinical hypercortisolemia could be the driver for the increased metabolic alterations seen in patients with Conn syndrome.
-
The identification of these dual secretors before adrenal venous sampling could alert the clinician about possible equivocal test results.
-
The identification of these dual secretors before unilateral adrenalectomy could avoid unexpected postoperative adrenal crises.
-
Hyperfunctioning adrenal and ovarian lesions can coexist, and the clinical manifestations associated with hypercortisolemia can masquerade the hyperandrogenic findings.

Summary
HAIR-AN syndrome, the coexistence of Hirsutism, Insulin Resistance (IR) and Acanthosis Nigricans, constitutes a rare nosologic entity. It is characterized from clinical and biochemical hyperandrogenism accompanied with severe insulin resistance, chronic anovulation and metabolic abnormalities. Literally, HAIR-AN represents an extreme case of polycystic ovary syndrome (PCOS). In everyday practice, the management of HAIR-AN constitutes a therapeutic challenge with the available pharmaceutical agents. Specifically, the degree of IR cannot be significantly ameliorated with metformin administration, whereas oral contraceptives chronic administration is associated with worsening of metabolic profile. Liraglutide and exenatide, in combination with metformin, have been introduced in the management of significantly obese women with PCOS with satisfactory results. Based on this notion, we prescribed liraglutide in five women with HAIR-AN. In all participants a significant improvement regarding the degree of IR, fat depositions, androgen levels and the pattern of menstrual cycle was observed, with minimal weight loss. Furthermore, one woman became pregnant during liraglutide treatment giving birth to a healthy child. Accordingly, we conclude that liraglutide constitutes an effective alternative in the management of women with HAIR-AN.
Learning points:
-
HAIR-AN management is challenging and classic therapeutic regimens are ineffective.
-
Literally HAIR-AN syndrome, the coexistence of Hirsutism, Insulin Resistance and Acanthosis Nigricans, represents an extreme case of polycystic ovary syndrome.
-
In cases of HAIR-AN, liraglutide constitutes an effective and safe choice.

Summary
Primary amenorrhea could be caused by disorders of four parts: disorders of the outflow tract, disorders of the ovary, disorders of the anterior pituitary, and disorders of hypothalamus. Delay in diagnosis and hormone substitution therapy causes secondary osteoporosis. Herein, we report a case of a 23-year-old phenotypical female who presented with primary amenorrhea from 46, XX gonadal dysgenesis but had been misdiagnosed as Mayer–Rokitansky–Kuster–Hauser (MRKH) syndrome or Mullerian agenesis. The coexistence of gonadal dysgenesis and MRKH was suspected after laboratory and imaging investigations. However, the vanishing uterus reappeared after 18 months of hormone replacement therapy. Therefore, hormone profiles and karyotype should be thoroughly investigated to distinguish MRKH syndrome from other disorders of sex development (DSD). Double diagnosis of DSD is extremely rare and periodic evaluation should be reassessed. This case highlights the presence of estrogen deficiency state, the uterus may remain invisible until adequate exposure to exogenous estrogen.
Learning points:
-
An early diagnosis of disorders of sex development (DSD) is extremely important in order to promptly begin treatment, provide emotional support to the patient and reduce the risks of associated complications.
-
Hormone profiles and karyotype should be investigated in all cases of the presumptive diagnosis of Mayer–Rokitansky–Kuster–Hauser (MRKH) syndrome or Mullerian agenesis.
-
The association between 46, XX gonadal dysgenesis and Mullerian agenesis has been occasionally reported as a co-incidental event; however, reassessment of the presence of uterus should be done again after administration of exogenous estrogen replacement for at least 6–12 months.
-
A multidisciplinary approach is necessary for patients presenting with DSD to ensure appropriate treatments and follow-up across the lifespan of individuals with DSD.

Summary
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant condition characterized by parathyroid, anterior pituitary and enteropancreatic endocrine cell tumors. Neuroendocrine tumors occur in approximately in 5–15% of MEN1 patients. Very few cases of ovarian NETs have been reported in association with clinical MEN1 and without genetic testing confirmation. Thirty-three-year-old woman with MEN1 was found to have right adnexal mass on computed tomography (CT). Attempt at laparoscopic removal was unsuccessful, and mass was removed via a minilaparotomy in piecemeal fashion. Pathology showed ovarian NET arising from a teratoma. Four years later, patient presented with recurrence involving the pelvis and anterior abdominal wall. She was treated with debulking surgery and somatostatin analogs (SSAs). Targeted DNA sequencing analysis on the primary adnexal mass as well as the recurrent abdominal wall tumor confirmed loss of heterozygosity (LOH) at the MEN1 gene locus. This case represents to our knowledge, the first genetically confirmed case of ovarian NET arising by a MEN1 mechanism in a patient with MEN1. Extreme caution should be exercised during surgery as failure to remove an ovarian NET en masse can result in peritoneal seeding and recurrence. For patients with advanced ovarian NETs, systemic therapy options include SSAs, peptide receptor radioligand therapy (PRRT) and novel agents targeting mammalian target of rapamycin (mTOR) and vascular endothelial growth factor (VEGF).
Learning points:
-
Ovarian NET can arise from a MEN1 mechanism, and any adnexal mass in a MEN1 patient can be considered as a possible malignant NET.
-
Given the rarity of this disease, limited data are available on prognostication and treatment. Management strategies are extrapolated from evidence available in NETs from primaries of other origins.
-
Care should be exercised to remove ovarian NETs en bloc as failure to do so may result in peritoneal seeding and recurrence.
-
Treatment options for advanced disease include debulking surgery, SSAs, TKIs, mTOR inhibitors, PRRT and chemotherapy.

Summary
In this case report, we present a novel mutation in Lim-homeodomain (LIM-HD) transcription factor, LHX3, manifesting as combined pituitary hormone deficiency (CPHD). This female patient was originally diagnosed in Egypt during infancy with Diamond Blackfan Anemia (DBA) requiring several blood transfusions. Around 10 months of age, she was diagnosed and treated for central hypothyroidism. It was not until she came to the United States around two-and-a-half years of age that she was diagnosed and treated for growth hormone deficiency. Her response to growth hormone replacement on linear growth and muscle tone were impressive. She still suffers from severe global development delay likely due to delay in treatment of congenital central hypothyroidism followed by poor access to reliable thyroid medications. Her diagnosis of DBA was not confirmed after genetic testing in the United States and her hemoglobin normalized with hormone replacement therapies. We will review the patient’s clinical course as well as a review of LHX3 mutations and the associated phenotype.
Learning points:
-
Describe an unusual presentation of undertreated pituitary hormone deficiencies in early life
-
Combined pituitary hormone deficiency due to a novel mutation in pituitary transcription factor, LHX3
-
Describe the clinical phenotype of combined pituitary hormone deficiency due to LHX3 mutations
