Large Water-Clear-Cell Parathyroid Adenoma: A Report of a Rare Case

Water-clear-cell parathyroid adenomas are extremely rare tumors characterized by cells that contain clear, foamy cytoplasm. Here we report a case of a large water-clear-cell parathyroid adenoma in a 70-year-old male. The patient was presented to an outside hospital with severe abdominal pain and supporting CT imaging confirming a small bowel obstruction. Initial laboratory studies revealed hypercalcemia and elevated parathyroid hormone levels. Subsequent ultrasound imaging revealed a 2.7 × 2.1 cm neck mass suspicious for a parathyroid adenoma. A parathyroidectomy was performed, and microscopic evaluation revealed an expansile proliferation of cells with characteristic water-clear cell features. Although rare, water-clear-cell parathyroid adenomas are clinically indistinguishable from more common subtypes and should be considered in the differential diagnosis of an anterior neck mass.

Association of Major Depressive Disorder in Hyperparathyroidism: A Systematic Review

Major depressive disorder (MDD) is a common neuropsychiatry manifestation that is more prevalent lately. Many contributing factors are present (for example, neurochemical, physiological, pathophysiological, and endocrinological factors). Patients with increased serum parathyroid levels are usually linked to psychosis symptoms but not to depressive symptoms. We conducted this systematic review to explore a correlation between depressive disorder and increased serum parathyroid levels, a major endocrinological pathology, and help establish mental wellness in patients suffering from hyperparathyroidism. We conducted a thorough literature search using five major databases, MEDLINE, PubMed, PubMed Central (PMC), ScienceDirect, and Google Scholar, using three keywords-MDD, depression, and hyperparathyroidism. We included mixed method studies, including observational studies, non-randomized controlled trials, case reports, and review articles published in the last ten years, focusing on the adult and geriatric population (>18 years) and on depressive and anxiety symptoms associated with patients with hyperparathyroidism. We included 11 articles (seven observational studies + four case reports) for qualitative synthesis after screening the literature. The reviewed studies showed an association between high serum parathyroid level, high serum calcium level, high serum alkaline phosphatase level, low serum phosphorous level, and increased depressive neurocognitive symptoms. After a patient with hyperparathyroidism is treated for hypercalcemia or undergoes parathyroidectomy and the serum parathyroid levels are lowered, a decrease in severe depressive symptoms is noted. The qualitative analysis of the reviewed literature showed an association between major depressive disorder and hyperparathyroidism. This paper can guide clinicians to assess patients with increased serum parathyroid levels for depressive neuropsychiatric symptoms and plan treatment, as treatment of their hyperparathyroidism can significantly lower their depressive symptoms. More randomized controlled trials should be conducted to find the treatment effectiveness of depression in patients with hyperparathyroidism.

Frequency of Preoperative Localization Techniques of Parathyroid Adenoma at King Abdulaziz University Hospital, Saudi Arabia

Background Accurate preoperative radiological localization of parathyroid pathologies paves the way to enable less invasive surgical procedures. Results on the accuracy of the different diagnostic measures are conflicting. Also, little is known about the most common location of parathyroid lesions. This paper aims to determine the most common location of parathyroid adenoma and evaluate the diagnostic performance of radiological modalities such as ultrasonography, sestamibi scintigraphy/single-photon emission computerized tomography (SPECT), magnetic resonance imaging (MRI), and computed tomography (CT) scan for the preoperative localization of parathyroid pathologies. Methods This is a retrospective study. Data were collected from patients who underwent total or partial parathyroidectomy at King Abdulaziz University Hospital between January 2000 and March 2020. The parathyroid adenoma site was detected preoperatively by a radiological method and confirmed postoperatively by the histopathology report. The performance of each preoperative localizing radiological method was evaluated based on the accuracy in localizing parathyroid pathology. Results A total of 73 patients were included in the analysis, with females being the most common gender in the study at 64%. Only complete data files were included and incomplete data files were excluded. The most frequent mode of detecting parathyroid adenoma was a sestamibi/SPECT scan (62.5%) followed by a CT scan (50%), ultrasound (34.6%), and MRI (25%). The most common location of a parathyroid adenoma was the left side. Conclusion Sestamibi/SPECT is a frequent radiological method for detecting the parathyroid lesion site as compared with CT, MRI, and ultrasonography.
