[PRIMARY AND SECONDARY HYPERPARATHYROIDISM PRESENTING AS BROWN TUMOR]

Area of Science:

• Endocrinology
• Oral Pathology
• Oncology

Background:

• Hyperparathyroidism (HPT) can cause osteolytic lesions with giant granulomas, termed brown tumors.
• Brown tumors are an end-stage complication of HPT, typically affecting the mandible, clavicles, ribs, and pelvis.
• Maxillary brown tumor involvement is exceptionally rare.

Observation:

• Two distinct cases of brown tumors are presented.
• Case 1: Primary HPT with maxillary brown tumor.
• Case 2: Secondary HPT with mandibular brown tumor.

Findings:

• The study highlights the differential diagnosis and workup for jaw lesions presenting as brown tumors.
• Management strategies for these rare oral manifestations of HPT are discussed.

Implications:

• This research expands understanding of rare HPT complications in the maxillofacial region.
• It provides valuable insights for clinicians managing patients with HPT and jaw lesions.
• Early recognition and appropriate management are crucial for favorable patient outcomes.
