Chondroblastoma of the TMJ: A case report

Chondroblastoma is a highly destructive tumor, derived from immature cartilage cells, typically occurring in epiphyses of the long bones of adolescents and young adults. Those occurring in the temporal bone and TMJ area are likely to mimic TMJ symptoms. We describe the clinical presentation, radiographic features, differential diagnosis, and treatment for this unusual tumor. The relevant literature on the subject is reviewed, and recommendations for appropriate diagnostic investigation applicable for tumors in this region is presented.
