ARAYA, Ignacio; YANINE, Nicolás; CORNEJO, Marco  e  VILLANUEVA, Julio. Maxillary brown tumour refractory to conventional therapy. Rev Esp Cirug Oral y Maxilofac [online]. 2014, vol.36, n.1, pp.21-26. ISSN 2173-9161.  https://dx.doi.org/10.1016/j.maxilo.2012.01.005.

A case is presented of a 29 year-old male patient suffering from chronic renal failure, secondary hyperparathyroidism and multiple osteolytic lesions in cranio-maxillo-facial structures, and with a histological diagnosis of giant cell lesions. The larger lesion affected the superior maxillary, a structure rarely compromised by this type of injury. This brown tumour caused a large facial deformity and compromised the orbital floor, maxillary sinus and the corresponding nostril. There was no evidence of tumour regression after parathyroidectomy and the serum calcium levels returned to normal. Finally, surgical remodelling of the maxillary brown tumour was performed, and no recurrence has been observed for 7 years.
