Introduction: Primary hyperparathyroidism (PHPT) is a rare endocrine disorder in adolescents, characterized by excessive parathyroid hormone (PTH) secretion leading to hypercalcemia and various systemic manifestations.
Case Report: We present a case of a 19-year-old female with PHPT secondary to parathyroid adenoma, who initially presented with right distal thigh pain and pathological fracture. A diagnostic workup revealed hypercalcemia, elevated PTH levels, and multiple osteolytic lesions throughout her skeletal system. Radiological imaging confirmed extensive bone involvement, including lytic lesions in the femur, phalanges, and skull. Surgical exploration and parathyroidectomy were performed, with histopathology confirming adenoma. Postoperative management included calcium supplementation to manage transient hypocalcemia.
Conclusion: This case underscores the diagnostic challenges and aggressive skeletal manifestations of PHPT in young patients, emphasizing the importance of early recognition and intervention to prevent long-term complications.

The aim of the study was to validate a new method for semiautomatic subtraction of [Tc]Tc-sestamibi and [Tc]NaTcO SPECT 3-dimensional datasets using principal component analysis (PCA) against the results of parathyroid surgery and to compare its performance with an interactive method for visual comparison of images. We also sought to identify factors that affect the accuracy of lesion detection using the two methods. Scintigraphic data from [Tc]Tc-sestamibi and [Tc]NaTcO SPECT were analyzed using semiautomatic subtraction of the 2 registered datasets based on PCA applied to the region of interest including the thyroid and an interactive method for visual comparison of the 2 image datasets.

Objective: Pituitary adenomas (PAs) are one of the three major lesions in Multiple Endocrine Neoplasia type 1 (MEN1), with a prevalence of 32 to 58%, yet their specific risk factors remain unidentified. This study aimed to identify predictors influencing PA occurrence in MEN1.
Methods: This nationwide, multicenter, retrospective cohort study involved 240 MEN1 patients, 55.

Parathyroid hormone (PTH) assays are not standardized and therefore PTH results are interpreted using manufacturer-provided assay-specific reference intervals. Assay-specific PTH reference intervals, however, do not account for between-assay differences and lead to discordance in the diagnosis of normocalcaemic primary hyperparathyroidism (NCPHPT). PTH increases with age independent of vitamin D, renal function, phosphate and ionized calcium.

Parathyroid carcinoma is an exceptionally rare malignant tumor of the parathyroid gland. Clinically, it most often presents as severe primary hyperparathyroidism. Diagnosis relies on histopathological analysis, although it is often difficult to establish due to the lack of clearly pathognomonic criteria.
