Traumatic bone cysts (TBCs) are uncommon, nonneoplastic lesions occurring more commonly in the metaphysis of the long bones and contribute to only 1% of the cysts occurring in the jaws. Seen more commonly in the mandible between the canine and third molar, their occurrence in the ramus-condyle region is very rare. The radiographic appearance of this lesion is like odontogenic keratocyst (OKC) or ameloblastoma and, therefore, extremely challenging to diagnose. Misdiagnosis often results in aggressive treatment for an otherwise innocuous entity. The purpose of this article is to encourage the surgeon to consider the possibility of a TBC when encountering asymptomatic large lytic lesions in the ramus of the mandible especially in younger individuals to avert an extensive radical surgery.

UI	MeSH Term	Description	Entries
D008334	Mandible	The largest and strongest bone of the FACE constituting the lower jaw. It supports the lower teeth.	Mylohyoid Groove,Mylohyoid Ridge,Groove, Mylohyoid,Grooves, Mylohyoid,Mandibles,Mylohyoid Grooves,Mylohyoid Ridges,Ridge, Mylohyoid,Ridges, Mylohyoid
D009807	Odontogenic Cysts	Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinized (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation.	Keratocysts,Cyst, Odontogenic,Cysts, Odontogenic,Keratocyst,Odontogenic Cyst

D001845	Bone Cysts	Benign unilocular lytic areas in the proximal end of a long bone with well defined and narrow endosteal margins. The cysts contain fluid and the cyst walls may contain some giant cells. Bone cysts usually occur in males between the ages 3-15 years.
