Hyperparathyroidism-jaw tumor syndrome

Last edited: 4/15/2026

Overview

Hyperparathyroidism-jaw tumor syndrome is a rare genetic disorder characterized by hyperparathyroidism, ossifying fibromatosis of the jaw, and an increased risk of renal tumors and nephroblastomatosis 2.

Diagnosis

  • Presence of hyperparathyroidism with elevated calcium levels 2
  • Ossifying fibromatosis or fibrous lesions in the jaw 2
  • Renal hamartomas or nephroblastomatosis 2
  • Macrosomia and visceromegaly in affected individuals 2
  • Unusual facial features and potential early lethality 2
  • Consider differential diagnosis in cases of fetal ascites without hydrops 2
  • Management

  • Treatment primarily focuses on managing hyperparathyroidism, often requiring parathyroidectomy 2
  • Surveillance for renal tumors and nephroblastomatosis with regular imaging studies 2
  • No specific drug treatments mentioned for the syndrome itself 12
  • Special Populations

  • No specific guidance provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 2
  • Key Recommendations

  • Perform regular monitoring for hypercalcemia and renal abnormalities in affected individuals (Evidence: Expert opinion) 2
  • Consider surgical intervention for severe hyperparathyroidism (Evidence: Expert opinion) 2
  • Early surveillance imaging for renal tumors and nephroblastomatosis is recommended (Evidence: Expert opinion) 2
