Background: Brown tumour of the cervical spine is very rare and is formed due to focal altered bone remodelling secondary to persistent and uncontrolled primary or secondary hyperparathyroidism. It is considered an extreme form of osteitis fibrosa cystica that occurs in the settings of persistently elevated parathyroid hormone.Case Report: This a unique lesion presented in a 48 year old male with recurrent bone pain and known End Stage Renal Disease (ESRD) on maintenance haemodialysis. The main clinical complaints were weak and painful legs and the initial presentation was after the patient collapsed at home and fractured spinal level C2. The initial assessment included blood tests and radiological imaging. CT scanning of the spine revealed a destructive lytic lesion with loss of height and architectural changes of the C2 vertebral body and cord compression.  The differentials included an acute fracture, a metastatic lesion and Brown’s tumour.  Further imaging with an MRI of the spine and PET-CT were performed which confirmed the above lesion and excluded metastatic disease and bone marrow infiltration. A CT guided bone biopsy followed. The patient continued to receive medical treatment for secondary hyperparathyroidism and the C2 fracture was managed with orthosis through a protective hard collar.Discussion: An up to date literature review revealed very few cases of Brown tumour of the cervical spine and there was only one previous case with C2 involvement due to primary hyperparathyroidism and one due to secondary hyperparathyroidism.  Clinicians must be aware of the varied presentations of Brown’s tumour to identify and provide the appropriate management.

Brown tumours are rare osteolytic lesions that occur secondary to hyperparathyroidism (HPT). In 2% of all cases, the craniofacial bones are affected, most frequently the mandible. HPT is classified according to aetiology into three types, of which tertiary HPT is the rarest. Here we present the case of a 42-year-old man who had received a renal transplant 16 years previously and was referred due to swelling on the right side of his jaw. An orthopantomogram revealed a multilocular radiolucency in the right body of the mandible. The bony lesion was treated by surgical enucleation. After histopathological examination of the lesion, the diagnosis of brown tumour of the mandible secondary to tertiary HPT was reached. The patient’s recovery was uneventful and follow-up radiography showed good bone healing.

BACKGROUND: The hyperparathyroidism (HPT) is a condition in which the parathyroid hormone (PTH) levels in the blood are increased. HPT is categorised into primary, secondary and tertiary. A rare entity that occurs in the lower jaw in association with HPT is the so-called brown tumour, which an osteolytic lesion is predominantly occurring in the lower jaw. It is usually a manifestation of the late stage of the disease. Osteosclerotic changes in other bones are almost always associated with renal osteodystrophy in secondary HPT and are extremely rare in primary HPT. This article reports a rare case of a brown tumour in the mandible as the first sign of a severe primary HPT, associated with osteosclerotic changes on the skull.CASE REPORT: A brown tumour in the mandible was diagnosed in 60 - year old female patient with no previous history of systemic disease. The x - rays showed radiolucent osteolytic lesion in the frontal area of the mandible affecting the lamina dura of the frontal teeth, and skull osteosclerosis in the form of salt and pepper sign. The blood analyses revealed increased values of PTH, calcitonin and β – cross-laps, indicating a primary HPT. The scintigraphy of the parathyroid glands showed a presence of adenoma in the left lower lobe. The tumour lesion was surgically removed together with the lower frontal teeth, and this was followed by total parathyroidectomy. The follow - up of one year did not reveal any signs of recurrence.CONCLUSION: It is critical to ensure that every osteolytic lesion in the maxillofacial region is examined thoroughly. Moreover, a proper and detailed systemic investigation should be performed. Patients should undergo regular check-ups to prevent late complications of HPT.

Brown tumour is an uncommon focal giant cell lesion that arises as a result of direct effect of parathyroid hormone on bone tissue in patients with hyperparathyroidism. The lesion is characterized by extensive bone resorption which is replaced by fibrovascular tissue and giant cell with abundant deposit of haemosiderin. A rare case of Brown tumour in maxilla and mandible in 57-year-old female patient is reported. This case report highlights the importance of detailed systemic investigation for all the maxillofacial lesions since it could be the diagnostic attribute of the systemic diseases.
