Pleomorphic adenoma in an atypical location near the temporomandibular joint: A case report
Smolka, Wenko / Eggensperger, Nicole / Stauffer-Brauch, Edouard Jean / von Bredow, Ferdinand / Iizuka, Tateyuki
Pleomorphic adenomas primarily arise in the major salivary glands, especially in the parotid. The most common area is the lower pole superficial to the plane of the facial nerve. In this report, a pleomorphic adenoma in an atypical location-the region of the temporomandibular joint (TMJ)-is presented. The tumor was solitary, closely attached to the capsule of the TMJ and superior to the parotid gland, with clear demarcation. Clinically, the tumor resembled TMJ pathology, but MRI examination led to diagnosis of a benign tumor attached to the TMJ. This report shows that pleomorphic adenoma can be a possible diagnosis for lesions at the joint capsule.
