Summary
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive inherited syndrome caused by mutations in autoimmune regulator (AIRE) gene. The three clinical components of this syndrome are mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency. In addition to these frequent symptoms, many other components have been reported including gastrointestinal manifestations.We report a case of a 17-year-old Caucasian female patient diagnosed with APECED who presented with acute abdominal pain. Her medical history revealed chronic digestive discomfort without bowel movement disorders. The patient needed a significant increase in doses of calcium supplementation and hydrocortisone which appeared to be partially inefficient. Investigation with esophagogastroduodenoscopy and biopsy showed autoimmune atrophic gastritis. The patient eventually needed increasing doses of treatment received in order to achieve desired clinical and biological therapeutic goals.
Learning points
-
Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive inherited syndrome caused by mutations in the autoimmune regulator (AIRE) gene.
-
The three clinical components of this syndrome that appear in early childhood are mucocutaneous candidiasis, hypoparathyroidism, and primary adrenal insufficiency.
-
In addition to these frequent symptoms, many other components have been reported including gastrointestinal manifestations like atrophic gastritis. They can be caused by many abnormalities including atrophic gastritis and the modification of intestinal biofilm and microbiota.
-
Early diagnosis and treatment of gastrointestinal manifestations associated with APECED prevent multiple life-threatening consequences like acute adrenal crisis and severe symptomatic hypocalcemia.

Summary
Doege–Potter syndromeis a paraneoplastic syndrome characterized by nonislet cell tumor hypoglycemia due to a solitary fibrous tumor, which produces insulin-like growth factor II. In this report, we present the case of a 67-year-old male with recurrent and refractory hypoglycemia due to DPS successfully treated with imatinib. He initially presented with neuroglycopenic symptoms and dyspnea secondary to a giant tumor in the left hemithorax, which was totally resected. During follow-up, 7 years later, he presented with thoracoabdominal tumor recurrence associated with severe hypoglycemia and underwent subtotal tumor resection, with a subsequent improvement of symptoms. The following year, he had a recurrence of his intra-abdominal tumor, which was unresectable, associated with severe hypoglycemia refractory to dextrose infusion and corticosteroids, thus receiving imatinib with a favorable response. The clinical presentation, diagnostic approach, progression of the disease, and response to treatment with imatinib in the management of a patient with large, recurrent, and unresectable mesenchymal tumors with insulin-like growth factor-2 secretion causing hypoglycemiahighlight the importance of this case report.
Learning points
-
Doege–Potter syndrome (DPS) is a rare cause of tumoral hypoglycemia of non-pancreatic origin.
-
Some malignant or benignant neoplasms have ectopic secretion of insulin-like growth factor-2.
-
Total surgical removal is the principal treatment in patients with DPS.
-
Tyrosine kinase inhibitors management in DPS may contribute to improved tumor control in patients with unresectable tumors and severe hypoglycemia.

Summary
A 55-year-old patient was admitted to our department for the management of a repetitive alteration of consciousness. Biological investigation results were consistent with endogenous hyperinsulinemic hypoglycemia. Insulinoma was therefore suspected. Abdominal computed tomography and endoscopic ultrasound showed no obvious pancreatic mass.Somatostatin receptor scintigraphy showed abnormal radioactive uptake in both the pancreatic tail and the uncinate process. Contrariwise, abdominal magnetic resonance imaging showed a unique lesion in the pancreas tail. The patient was then proposed for pancreatic surgery. Both intraoperative manual palpation and intraoperative ultrasonography of the pancreas showed a single corporal lesion of 1.5 cm. No lesion was found in the uncinate process. After a left pancreatectomy, the lesion was histopathologically confirmed to be a well-differentiated neuroendocrine tumor. The symptoms of the patient resolved almost immediately following the surgery. The follow-up is one and a half years to date.
Learning points
-
The exact preoperative localization of the pancreatic mass remains the most challenging part of insulinoma diagnostic workup.
-
The radiologist’s experience is the best warrantor to a precise localization of the tumor.
-
111In-DTPA-octreotide uptake in the pancreatic uncinate process may be physiological and its interpretation must, therefore, be vigilant.
-
Manual palpation along with intraoperative ultrasonography is considered as the most effective method for the localization of insulinomas during open surgery.

Summary
We report the successful delivery of a healthy baby after intracytoplasmic sperm injection (ICSI) with frozen-thawed autologous sperm, cryostored for 26 years, the longest successful autologous sperm cryostorage reported. Sperm was cryostored for a 15-year-old boy at the time of his cancer diagnosis. Semen samples were frozen with cryoprotectant, using a graduated vapour-phase nitrogen protocol. Straws were stored in a large vapour-phase nitrogen tank until transfer for use. The couple underwent a single ICSI–in vitro fertilisation procedure using the frozen-thawed sperm with a transfer of five fertilised embryos, resulting in the live birth of a healthy baby boy. This reinforces the importance of offering sperm cryopreservation to men who have not completed their family prior to gonadotoxic treatment for cancer or other diseases. As practical, low-cost fertility insurance, it should be offered to any young man who can collect semen and it provides essentially unlimited duration of fertility preservation.
Learning points
-
Gonadotoxic chemo or radiotherapy treatment for cancer or other diseases usually causes temporary or permanent male infertility.
-
Sperm cryostorage serves as a practical, low-cost insurance to facilitate future paternity.
-
All men who have not completed their families and are scheduled for gonadotoxic treatments should be offered sperm cryostorage.
-
There is no lower age limit for young men who can collect semen.
-
Sperm cryostorage offers essentially indefinite duration for the preservation of male fertility.

Summary
Paraneoplastic syndromes (PS) are uncommon and are known to mimic other clinical entities, often carrying significant morbidity and mortality. The commonest cause of extra-ocular muscle enlargement (EOME) is thyroid eye disease (TED). Rarely, PS can cause EOME and masquerade as TED. We describe a 52-year-old female who presented with diarrhoea, acute kidney injury and electrolyte imbalance. An ophthalmic review identified right upper lid retraction. MRI orbits showed increased thickness of the inferior and medial recti bilaterally, presumed as TED. Whilst investigating her diarrhoea, imaging revealed a large rectosigmoid tumour which required surgical excision. In the context of electrolyte disturbance and acute kidney injury, a diagnosis of McKittrick–Wheelock syndrome (MWS) was made. Following successful surgery, electrolyte imbalance, diarrhoea and eyelid retraction improved. Repeat MRI orbits displayed complete resolution of EOME. To our knowledge, this is the first case of MWS presenting with PS-EOME masquerading as TED.
Learning points
-
McKittrick–Wheelock syndrome (MWS) is a rare disorder, although likely under-recognised, which is characterised by diarrhoea, dehydration and electrolyte depletion that results from a hypersecretory colorectal neoplasm.
-
Definitive treatment of MWS involves the resection of the colorectal neoplasm.
-
Bilateral ophthalmopathy that appears to be Graves’ ophthalmopathy on imaging, though clinical and biochemical evidence fails to identify a thyroid pathology, has been associated with malignancy on rare occasions. Such patients should be investigated for potential malignant causes of their ophthalmopathy.

Summary
A 31-year-old woman with complete androgen insensitivity syndrome (CAIS) experienced breast volume fluctuations during biphasic hormone replacement therapy consisting of estradiol and cyclical dydrogesterone, a progestin. 3D breast volume measurements showed a 100 cc volume (17%) difference between estradiol monotherapy and combined estradiol and dydrogesterone treatment. Progestogen-dependent breast volume changes have not been reported in the literature. Our findings suggest a correlation between progestogen use and breast volume. Due to the rapid cyclical changes, we hypothesize that the effect is caused by fluid retention.
Learning points
-
There is limited reports available on the effects of progesterone on breast development and volume.
-
3D imaging provides an easy-to-use method to quantify breast volume.
-
The patient in our case description clearly showed that cyclic progesterone use might induce substantial cyclic changes in breast volume.
-
In women with complete androgen insensitivity syndrome (CAIS), monotherapy with estrogen or continuous supplementation of progesterone might be preferable over cyclic progesterone use.

Summary
We report a rare case of biopsy-proven isolated immunoglobulin G4 (IgG4)-related hypophysitis and Rathke’s cleft cyst (RCC) presenting as panhypopituitarism. A 54-year-old Caucasian female presented with symptoms of slurred speech, altered mental status, polyuria and polydipsia and was found to have panhypopituitarism. Brain MRI showed a suprasellar mass with suspected intralesional hemorrhage. She underwent trans-sphenoidal resection due to MRI evidence of compression of the optic chiasm and left optic nerve. Preoperatively, she was started on hydrocortisone, levothyroxine and desmopressin. Histopathology demonstrated a RCC with adjacent lymphoplasmacytic hypophysitis with numerous IgG4-immunoreactive plasma cells. Hydrocortisone was stopped at 10 months after confirming hypothalamic-pituitary-adrenal (HPA)-axis recovery and desmopressin was stopped at 1 year. There was recurrence of a cystic mass at 1 year follow-up. Over 4 years of follow-up, she continued to require levothyroxine, and the mass remained stable in size. In order to begin to understand how this case’s unique histopathological presentation influences clinical presentation, pituitary imaging and prognosis, we present an accompanying literature review.
Learning points
-
Isolated IgG4 hypophysitis and coexisting Rathke’s cleft cyst is a rare condition, which presents a diagnostic challenge.
-
Recognizing its characteristic features can assist with early recognition and initiation of therapy to promote optimal outcomes.
-
Further studies investigating the mechanisms promoting co-occurrence of these entities and their effect on prognosis are needed.

Summary
A 44-year-old athletic man presented in 2009 with severe low back pain. Dual-energy x-ray absorptiometry revealed severe osteoporosis; serum testosterone was 189 ng/dL while serum estradiol (E2) measured by liquid chromatography/mass spectrometry was 8 pg/mL. DNA was extracted and sequenced from a blood sample from the patient since his maternal first cousin also had low bone mass and both patients were screened for aromatase dysfunction by PCR analysis for the CYP19A1 gene, which encodes aromatase. No known pathologic mutations were observed in the coding exons, but novel single nucleotide polymorphisms were detected both in the proband and in his cousin. Treatment with topical testosterone started in August 2010. Over the next 8 years, testosterone dosage was varied and switched from topical gel to injections and maintained on depo-injections of testosterone at about 60 mg once per week. Re-examination in March 2012 included a brain MRI to exclude pituitary lesions; hyperparathyroidism was ruled out (normal serum parathyroid hormone, calcium, and calcium to phosphorous ratio) and celiac disease was excluded (negative transglutaminase antibodies). Follow-up in October 2018 showed improved bone mineral density of the lumbar spine by 29% and of the left femoral hip by 15% compared to baseline measurements. This reveals the importance of measuring serum E2 for making the correct diagnosis, as well as for monitoring a therapeutic effect. Herein, we propose treatment of male osteoporosis where serum E2 levels are below about 20 pg/mL with testosterone to reverse osteoporosis.

Summary
A 59-year-old male presented with an accidental thyroid mass in 2022. Ultrasound and CT scan showed a nodule 5.2 × 4.9 × 2.8 cm (EU-TIRADS 4) in the right lobe of the thyroid gland. Taking into account the results of the fine needle aspiration biopsy (Bethesda V), intrathyroid localization, and absence of clinical symptoms, a malignant tumor of the thyroid gland was suspected. The patient underwent total thyroidectomy using fluorescence angiography with indocyanine green, and two pairs of intact parathyroid glands were visualized in typical localization. Unexpected histological and immunohistochemistry examinations revealed parathyroid carcinoma. Due to the asymptomatic course of the disease and atypical localization of parathyroid tumor, primary hyperparathyroidism was not suspected before the surgery. The diagnosis of asymptomatic intrathyroid parathyroid cancer is a serious diagnostic challenge for a wide range of specialists.
Learning points
-
Parathyroid cancer is a rare disease that may be asymptomatic.
-
Intrathyroidal localization of parathyroid carcinoma is casuistic and challenging for diagnosis, and the treatment strategy is not well defined.
-
Preoperative parathyroid hormone and serum calcium testing are recommended for patients with solid thyroid nodules (Bethesda IV–V).

Summary
Acute illness-related stress can result in severe hypercortisolism and bilateral adrenal enlargement in certain patients. We report a case of stress-induced hypercortisolism and bilateral adrenal enlargement in a patient admitted for acute respiratory distress and cardiogenic shock. Bilateral adrenal enlargement and hypercortisolism found during hospitalization for acute illness resolved 3 weeks later following the resolution of acute illness. Acute illness can be a precipitating factor for stress-induced hypercortisolism and bilateral adrenal enlargement. We hypothesize that increased adrenocorticotrophic hormone mediated by corticotrophin-releasing hormone from physical stress resulted in significant adrenal hyperplasia and hypercortisolism. This mechanism is downregulated once acute illness resolves.
Learning points
-
Adrenal enlargement with abnormal adrenal function after stress is uncommon in humans; however, if present, it can have self-resolution after the acute illness is resolved.
-
Stress induces enlargement of the adrenals, and the degree of cortisol elevation could be very massive. This process is acute, and the absence of cushingoid features is expected.
-
Treatment efforts should be focused on treating the underlying condition.
