Heamangioma in parotid gland encroaching on the temporomandibular joint: A case report

The majority of swellings in the parotid region are sialadenitis, neoplastic lesion or lymph node. Vascular malformation is a rare cause of swelling of the parotid gland. Parotid heamangioma usually presents as a cystic swelling in the preauricular area but may mimic sialadenitis making the diagnosis difficult. We are reporting, to our knowledge, the first case of parotid gland heamangioma with its clinical presentation, radiological and surgical features which extended medially to the temporomandibular joint. The rarity of such condition in head and neck region and misdiagnosis or failing to diagnose make this case more interesting to the maxillofacial surgeon.
