A 25-year old female patient was referred to our department with a mass at the level of the right temporomandibular joint (TMJ). The patient experienced symptoms of paroxysmal pain of the TMJ and weight loss. Magnetic resonance imaging (MRI) revealed a tumour in the right masticatory space extending into the right TMJ, with invasion of the temporal bone. Surgical resection of the mass and total TMJ replacement surgery with a custom-made pros-thesis were performed. Final histological diagnosis of the resected specimen showed a dif-fuse-type tenosynovial giant cell tumour (D-TGCT). The multidisciplinary team’s decision was to give adjuvant radiotherapy; however, the patient declined further treatment. At 6 months follow-up, the patient had an excellent recovery with no signs of tumour recurrence on MRI. This is the first described case of D-TGCT treated with total TMJ replacement sur-gery using a custom-made alloplastic device.
