Multiple choice quiz based on Bailey's 4th ed. Otolaryngology Head and Neck Surgery Chapter 112: Odontogenic Cyts, Tumors, and Related Jaw Lesions
Observation with close follow up
Segmental resection of the mandible with postoperative radiation
Recontouring of the jaw surgically and orthodontics to correct malocclusion
Enucleation of the cyst with osseocurretage
The specimen exibits curvilinear portions of woven bone, sithout appositional osteoblasts, in a background of connective tissue stroma.
The patient is at an increased risk for sarcomatous transformation of the disease
The patient is likely to have other similar lesions in his longbones over the course of his life
Appropriate treatment would have been delayed contouring of the jaw after final growth has occurred.
This disease is a sporadic mutation in the alpha-subunit of a signal transducing G-protein

A wide range of recurrence from 5-60% depending on the surgical technique.
The preferred treatement is surgical enucleation and osseous curettage, removing the specimen in one piece.
Histologically distinct, this speicimen displays the characterisitc parakaeratinazation, with the flat epithelial-connective tissue interface resulting in a separation of the epithelium on processing.
When multiple lesions of this nature appear, one should consider the diagnosis of McCune-Albright Syndrome.
The lesions grow in a multilocular bosselated fashion with daughter cysts that extend into the surrounding bone. Because of this relationship, the tendency for recurrence is high, particularly if the original surgical treatment does not result in complete removal of the lesion.
