Core Tip

Core tip: We present an unusual parotid gland papillary cystadenoma that was mistaken for a temporomandibular joint (TMJ) tumor. Surgeons should pay particular attention to the integrity of the interstitial space around the condyle in preoperative magnetic resonance imaging and computed tomography. If the space is intact, the mass may come from the parotid gland, otherwise, it is of TMJ origin. The tumor‘s origin determines operative planning and process.
