Brown Tumours: A Case of a Non-Healing Tooth Socket
The present case has been published in the journal EC Dental Science. Brown tumours are boney complications of hyperparathyroidism. They giant cell lesions that often appear as an expansile osteolytic lesion of the bone. In the present case, the authors discuss the diagnosis and management of a brown tumour that presented as a non-healing extraction socket.

A 59 year old male presented with a one year history of a non-healing extraction socket on the lower left mandible following the removal of the LL6. The socket was not associated with any acute symptoms such as pain or swelling, but lack of mucosal closure persisted despite local measures with his general dental practitioner. The patient had a medical background of hypercholestrolaemia, hypertension, and anxiety.

He previously had hyperparathyroidism as a result of a parathyroid adenoma, which was surgically removed 6 months after the dental extraction. Intra-oral examination revealed a suspicious-looking heterogenous lesion on the lower left alveolar ridge within the extraction socket.

Radiographically there was a diffuse area of irregular radiolucency along the lower left mandible which had a moth eaten appearance in the absence of retained tooth fragments.
An urgent incisional biopsy was undertaken which showed giant cells present.

Bloods revealed mildly elevated calcium levels and low levels of phosphate. A diagnosis of Brown’s Tumour was made and the area was curetted and treated with Leukocyte-Platelet Rich Fibrin (L-PRF) and primary closure.
