Who can safely discontinue lifelong follow‐up among patients with sporadic pheochromocytoma and paraganglioma?

Journal of Internal Medicine, Volume 299, Issue 5, Page 615-627, May 2026.
Abstract Background Current guidelines recommend at least 10 years of follow‐up for all pheochromocytoma and paraganglioma (PPGL) patients and lifelong monitoring for high‐risk individuals. Nonetheless, data identifying patients who may not require routine lifelong follow‐up are scarce. Methods Among 999 patients with PPGL, 703 who were non‐metastatic,

Diffuse and Prolonged Bone Pain Revealing Tumor‐Induced Osteomalacia: A Case Report

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Tumor‐induced osteomalacia should be considered in patients with unexplained bone pain and fractures. Advanced imaging, such as Ga68‐DOTATATE PET/CT, enables precise tumor localization, and surgical excision can rapidly normalize phosphate metabolism and resolve symptoms, underscoring the importance of early diagnosis and intervention.
