Brown Tumor and Secondary Hyperparathyroidism

The Refractory Tertiary Hyperparathyroidism Presenting With Retro- Orbital Brown Tumor: a Case Report

“…Unusual locations for BT, including the forearm, foot, jaw, mandible, sphenoid sinus, and calcaneus, have been reported. Orbital bones are exceptionally rare reported as BT location [12,13]. Exophthalmos and visual impairment are the most common complaints among patients with orbital BT.…”

Single-Step Primary Reconstruction After Complex Fronto-Orbital Brown Tumor Resection Using Computed-Designed Peek Implant

“…22 Only few cases have been reported in the fronto-orbital region. [9][10][11][12][13][14][15][16][17] When the orbit is affected, the presenting symptoms include a palpable mass, pain, proptosis, diplopia, impaired extrinsic ocular motility or decreased visual acuity.…”

Orbital Involvement in Craniofacial Brown Tumors

“…There are at least 17 reports of orbital brown tumors in primary or secondary hyperparathyroidism. [2][3][4][5][6][31][32][33][34][35][36][37][38][39][40][41] In 8 of these cases, the maxillary bone was compromised. 31,[33][34][35][36][37]39,40 Orbital invasion through lesions arising in the ethmoid or sphenoid sinuses 6,36,37,41,42 or frontal bone 2,4,5,32 have also been reported.…”

“…Due to the rarity of this entity, the ophthalmic literature on brown tumors is sparse and basically consists of case reports. [2][3][4][5][6] In this article, we report our experience with craniofacial brown tumors affecting the orbit in a large series of patients with primary and secondary hyperparathyroidism. …”
