We report a case of concomitant exacerbation of Graves orbitopathy (GO) and myasthenia gravis (MG) after SARS-CoV-2 infection. A 43-year-old woman had diplopia, proptosis, and swollen eyelids. Blood tests showed thyrotoxicosis and positive thyroid-stimulating hormone receptor antibodies, and orbital magnetic resonance imaging (MRI) showed enlarged extraocular muscles. She was therefore referred to our hospital with diagnosis of GO. Methylprednisolone pulse therapy (MPT) in combination with orbital radiotherapy were performed for 3 weeks, and ocular symptoms improved. At 41 weeks, the patient was infected with SARS-CoV-2 and felt sudden worsening of diplopia and ptosis. MRI showed an enlarged right inferior rectus muscle. MPT and orbital radiotherapy were performed again for 3 weeks for the suspected GO, but there was insufficient improvement of the ptosis. Serum antiacetylcholine receptor and anti-muscle-specific tyrosine kinase antibodies were negative, but the patient was further evaluated with repetitive nerve stimulation test and ice pack test, and diagnosis was double-seronegative MG. Pyridostigmine treatment led to dramatic improvement of the ptosis. SARS-CoV-2 infection could exacerbate MG as well as GO. Careful diagnosis is required for ocular symptoms after SARS-CoV-2 infection, especially when there is double-seronegative MG.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"3 2","pages":"luaf019"},"PeriodicalIF":0.0,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11775584/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143070044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pineal gland hormone melatonin regulates GH secretion in many mammals, including humans, although its role in modulating GH secretion has been debated. We describe the case of a young woman chronically taking melatonin for sleep disturbances, referring to her general practitioner for flushing that appeared just after starting melatonin intake. Laboratory findings showed elevated plasma levels of GH and insulin-like growth factor-1 (IGF-1). She did not show clinical features resembling acromegaly. The evaluation of pituitary and pituitary end organ hormones showed normal plasma levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), thyroid stimulating hormone (TSH), estradiol, free thyroid hormones, cortisol, and prolactin. Urinary 5-hydroxyindoleacetic acid levels were normal. One month after melatonin withdrawal, her plasma levels of GH, together with IGF-1, completely normalized. An oral glucose suppression test showed a normal response of GH secretion, further excluding an autonomous secretion. Physicians should be aware of the possible interference of melatonin on GH secretion to prevent misleading diagnosis of autonomous secretion thus avoiding valueless and costly clinical investigations.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"3 2","pages":"luaf006"},"PeriodicalIF":0.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11773383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143061363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the case of a patient with HPT-JT who carried a novel germline pathogenic CDC73 variant. A 27-year-old woman presented with thirst, polyuria, fatigue, constipation, and a history of fibro-osseous mandible lesions and endometrial polyps. Examination revealed hypercalcemia and grossly elevated PTH levels with hypercalciuria accompanied by a right lower parathyroid tumor with concordant imaging, suggesting primary hyperparathyroidism (PHPT). Given that she had early-onset PHPT and a history of fibro-osseous mandible lesions, HPT-JT was suspected. Genetic testing identified a novel frameshift variant in exon 1 of CDC73. En bloc resection was planned based on the suspicion of parathyroid carcinoma. However, because no findings suggestive of carcinoma were observed intraoperatively, thyroidectomy was not performed. Despite the surgery, PHPT persisted postoperatively, and further evaluation revealed the presence of a residual ectopic left upper parathyroid adenoma, necessitating additional surgery. High-impact pathogenic CDC73 variants are linked to a high risk of parathyroid carcinoma and multiglandular disease. In patients with such variants and clinically suspected parathyroid carcinoma, bilateral neck exploration with subtotal parathyroidectomy may be recommended, with en bloc resection added if intraoperative findings suggest carcinoma.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"3 2","pages":"luaf016"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11758138/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a 20-year-old woman presenting with polyuria, galactorrhea, amenorrhea, and substantial weight loss. Hormonal evaluation revealed hypopituitarism with arginine-vasopressin deficiency and hyperprolactinemia. Magnetic resonance imaging demonstrated pituitary stalk thickening and suprasellar extension, initially suggestive of hypophysitis. High-dose glucocorticoid therapy resulted in partial regression of the pituitary lesion but persistence of suprasellar involvement, prompting a transcranial stereotactic biopsy. Histopathological analysis confirmed isolated NS with noncaseating granulomas. The patient was treated with rituximab after partial response to glucocorticoids, achieving significant clinical and radiological improvement, although hormonal axis recovery was not observed. Hormone replacement therapy remains necessary. The case met the criteria for definitive type b NS, as no extraneural involvement was identified. This case underscores the diagnostic challenges of isolated NS and highlights the importance of considering histopathological confirmation in patients without systemic manifestations to guide treatment. Glucocorticoids are first-line therapy, but rituximab may be effective as a second-line option for refractory cases. Early diagnosis and tailored therapy are essential to improving outcomes in this rare and challenging condition.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"3 2","pages":"luaf014"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11758143/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He was treated with palliative stereotactic radiosurgery to the brain and skull base lesions. Thereafter, as no targetable genetic alteration was identified and antiangiogenic multikinase inhibitors were deemed at high risk of hemorrhagic complications, off-label systemic therapies were considered. The mechanistic target of rapamycin (mTOR) inhibitor everolimus could not be obtained due to lack of insurance coverage, so the patient was treated with single-agent pembrolizumab. He showed an initial remarkable response, but unfortunately had disease progression in the neck and upper mediastinum after 1 year of therapy. At that time, he was treated with external beam radiotherapy, with concomitant pembrolizumab. He was then found to have an CTSB::ALK fusion, which has previously been described in 2 cases of thyroid cancer. However, as he showed a positive response to radiation with pembrolizumab, he continued single-agent immune checkpoint inhibition and had a persistent marked response almost a year after completing radiation. The patient was then followed at an outside institution and was transitioned to hospice at time of progression per his preference. He died 4 years after his initial diagnosis.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"3 2","pages":"luaf015"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11758140/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a case of tumor-induced osteomalacia in which the tumor location could be determined by gallium 68 (68Ga)-DOTATOC positron emission tomography (PET)/computed tomography (CT). A 74-year-old woman had recurrent fractures and bone pain. Blood tests showed hypophosphatemia and elevated serum alkaline phosphatase and FGF23 levels and CT and bone scintigraphy showed multiple bone fractures. Tumor-induced osteomalacia was therefore suspected. Indium 111 (111In)-pentetreotide scintigraphy showed focus of increased activity in the head, and CT and magnetic resonance images showed a mass-like lesion in the posterior ethmoidal sinus. However, in systemic venous sampling, serum FGF23 level was highest in the left common iliac vein. 68Ga-DOTATOC PET/CT clearly demonstrated focal uptake in the left anterior inferior iliac spine consistent with systemic venous sampling. Retrospectively analyzed, focal uptake in the head was considered to be a physiological uptake in the pituitary gland. The tumor was resected and the pathological diagnosis was phosphaturic mesenchymal tumor. A combination of systemic venous sampling and 68Ga-DOTATOC PET/CT was useful in detection of a small FGF23-producing tumor. Precise tumor localization in such cases requires careful interpretation of scintigraphy.","PeriodicalId":73540,"journal":{"name":"JCEM case reports","volume":"3 2","pages":"luaf012"},"PeriodicalIF":0.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11758137/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
