Chondrocalcinosis

Rare Localization in the Temporomandibular Joint

Abstract

In this paper introduces a rare case of chondrocalcinosis of the temporomandibular joint secondary to hyperparathyroidism, diagnosed in a 64-year-old man. The patient complained of symptoms characterized by the presence of a swelling in the left pretragic preauricular region, accompanied by a limitation of the mandibular movements. Radiographic examinations suggested a diagnosis of synovial chondromatosis. Subsequently definitive histological analysis removed mass stated for a chondrocalcinosis of the left temporomandibular joint. The differential diagnosis is very hard, in this case it has been difficult for the rarity of the pathology described in literature; the exact diagnosis can be only formulated on histologic and citologic examination of the mass excised.
