Brown Tumour of Hyperparathyroidism in the Oral Cavity : About two Pediatric Cases
Objectives: The general prevalence of brown tumours is low (approximately 0.1%); however, it is increasingly found in primary and secondary hyperparathyroidism patients .
The main purpose of this work is to describe, through two rare cases, the brown tumours of hyperparathyroidism in children.
Despite being rare, it is important for nephrologists, primary care physicians, and dentists and especially pediatric dentists to be able to recognize this entity, so that intervention may be rendered early.
Methods: Two patients were referred to the Oral Medicine Service at La Rabta Hospital in Tunis, respectively in 2021 and 2022 : the first patient with the chief complaint of ectopic eruption of the canines and the second for evaluation of an oral lesion.
Both patients were suffering from chronic progressive renal failure associated to hyperparathyroidism and were on hemodialysis.
The clinical investigation revealed solid, rounded formation on mandibular for the first patient and on maxillary and mandibular for the second patient.
Further examination tools were used: a complete blood analysis and x-ray examinations were performed.
Results: The blood analysis showed increased values of parathyroid hormone for both of them.
A severe reduction of the bone density was observed in the affected area, as well. Also, the lamina dura of teeth was also affected for both of the two patients.
The principle treatment of the hyperparathyroidism associated with bone changes and highly increased blood markers is partial or total parathyroidectomy. It is assumed that after the removing of the reason for hyperparathyroidism, the bone changes will spontaneously regress.
This claim is supported particularly for the small tumours, however, in cases when the tumour dimensions interfere with the function and every - day activities of the patient, the surgical removal is a reasonable solution.
Conclusions: Patients with hyperparathyroidism should undergo regular check-ups to prevent late jaws complications.
