A Case of Squamous Papilloma in the Middle Ear, External Auditory Canal, and Infratemporal Fossa / 대한이비인후과학회지

ABSTRACT

Papilloma is a benign neoplasm confined almost exclusively to the sinonasal tract. And rare cases involving middle ear or external auditory canal, usually extended or contaminated from nasal cavity have been reported. We recently experienced a case of squamous papilloma involving middle ear, external auditory canal, and infratemporal fossa without any evidence of involving sinonasal tract. We present a review of literature and discuss the pathophysiology of the papilloma.
