Hemangioma of the joints are commonly found at knee joints, however, in the temporomandibular joint (TMJ) region juxta-articular hemangioma cannot be found in the literature.
We experienced a case of hemangioma of the TMJ and reported it. The patient was a 67-year-old woman with complaints of the tumor of the left TMJ region and pain during jaw movement. The tumor was elastic, soft, fluctuated, no tenderness to palpation and adherent to the underlying tissues. The volume change was seen with movement of jaw. When this mass was punctured, 1/ml of blood-like liquid was aspirated. The rentogenographic examination offered no findings, but the contrast radiography of the tumor showed radioopaque figure on the lateral side of the left TMJ, which disappered in 15 minutes. The tumor was removed under local anesthesia, and was found under lateral ligament of TMJ, but was not adherent to the capsule. The microscopic diagnosis was venous hemangioma.
There were no signs of recurrence at the last examination 5 years postoperatively.
