Background: Primary hyperparathyroidism is caused by the excessive growth of parathormone secretion, its consequence being hypercalcemia. The parathyroid adenoma is responsible for over half of primary hyperparathyroidism cases. The mandibular tumor can be the initial sign in the case of primary hyperparathyroidism.
Case Presentation: We present the case of a 33 year old patient with history of a mandibular operated tumor, repetitive pathological fractures and hypercalcemia manifestations. The level of the parathormone at the first measurement indicated a very high value. The parathyroid scintigraphy with 99mTc-MIBI (methoxy-isobutyl-isonitrile) evidenced a high uptake of the tracerin the superior mediastinum, suggestive for an ectopic parathyroid adenoma. The histopathological examination after surgery leads to the diagnosis of parathyroid adenoma. The association between the primary hyperparathyroidism, the mandibular tumour, the clinical history and the nuclear imaging lead to the diagnosis of primary hyperparathyroidism - Jaw tumor syndrome.
Conclusion: The hyperparathyroidism - Jaw tumor syndrome has a special clinical importance because of the severe and progressive symptomatology, and because of the risk of developing neoplasia of parathyroid glands, which have a reserved prognosis.

Hyperparathyroidism-jaw tumor syndrome is a rare form of syndromic primary hyperparathyroidism. We describe a young female with a history of common precursor B acute lymphoblastic leukaemia who was diagnosed with overt primary hyperparathyroidism due to a pathogenic CDC73 variant (c.25C > T).

Introduction And Importance: Primary hyperparathyroidism (PHPT) is a frequent complication to multiple endocrine neoplasia type 1 (MEN1), presenting challenges due to increased risk of multi-gland disease and recurrence post parathyroidectomy (PTX). This case report examines the management of PHPT in a MEN1 patient, emphasizing possible benefits from intraoperative parathyroid autofluorescence imaging (AF).
Case Presentation: A 21-year-old woman with MEN1 presented with mild hyperparathyroidism symptoms in 2014.

A 51-year-old female patient with diabetes mellitus and hypertension, exhibiting poor control of blood sugar and blood pressure, was unexpectedly found to have multiple large adrenal nodules, excessive cortisol secretion, and adrenocorticotropic hormone inhibition. Cortisol levels remained unresponsive to both low-dose and high-dose dexamethasone tests, leading to a diagnosis of primary bilateral macronodular adrenal hyperplasia. Concurrently, elevated blood calcium and parathyroid hormone levels, along with 99mTc-methoxyisobutyl isonitrile (99mTc-MIBI) imaging revealing increased 99mTc-MIBI uptake in the right inferior parathyroid gland, suggest the consideration of primary hyperparathyroidism.

Background/objective: Radiofrequency ablation (RFA) has been increasingly used as an alternative to surgery in patients with primary hyperparathyroidism who are unable or unwilling to have surgery.
Case Report: We present a case of a 64-year-old woman who had surgery for primary hyperparathyroidism complicated by osteoporosis. Preoperative imaging with 4-dimensional computed tomography scan suggested multigland disease; however, she had persistent hyperparathyroidism after parathyroid exploration.
