Chondroblastoma of the temporomandibular joint lateral capsule: a case report

Cranio. 2015 Oct;33(4):306-11. doi: 10.1080/08869634.2015.1097305. Epub 2015 Dec 29.

Abstract

Aim: Chondroblastoma is a rare, benign bone tumor that accounts for approximately 1% of all primary bone tumors. Chondroblastoma that occurs at the temporomandibular joint can exhibit symptoms similar to those associated with other temporomandibular disorders. This case study aims to present an eight-year followup of chondroblastoma occurring at the temporomandibular joint.

Methodology: The patient presented swelling in the left temporomandibular joint and trismus. Based oncomputed tomography and magnetic resonance imaging findings, a provisional diagnosis of synovial chondromatosis was made. Complete excision of the lesion was performed under general anesthesia.

Results: After histopathological examination, the lesion was finally diagnosed as chondroblastoma. Currently, 8 years after the operation, the patient has not experienced any symptoms or any notable complications.

Conclusions: Although chondroblastoma is a benign tumor, it shows aggressive characteristics with bone invasion. Therefore, precise diagnosis and proper treatment planning is crucial for successful treatment of chondroblastoma.

Keywords: Benign tumor; Chondroblastoma; Temporomandibular joint.
