Introduction and importance: Primary hyperparathyroidism is a prevalent source of hypercalcemia, predominantly attributed to a solitary adenoma in 80-85% of cases. Progress in imaging techniques has enhanced the accurate preoperative identification and targeted removal of hyperfunctional parathyroids in primary hyperparathyroidism (PHPT). The amalgamation of imaging methods or a "dual" approach, when congruent, enhances the precision of adenoma localization. Surgery re...

Introduction: Brown tumor or osteitis fibrocystica is a benign bone lesion reflecting an abnormality of bone metabolism in the context of hyperparathyroidism. It can affect the entire skeleton, including the pelvis, ribs, clavicles and extremities. Involvement of the maxillary bone is very uncommon. We present a case of multiple brown tumors with an unusual maxillo-mandibular localization, revealed by a disorder of phosphocalcic metabolism and tertiary hyperparathyroidism. Thi...

Introduction: Digestive neuroendocrine tumors (DNETs) represent a heterogeneous group of tumors. This heterogeneity is manifested by the variable localization of these tumors but also by a great clinical and biological diversity. Thus, they occupy an increasingly important place in digestive oncology.NETs are very rare and represent about 1% of all digestive tumors, due to their slow evolution. The majority of them develop in the digestive tract (67.5%) ...
