Warning

Cholesteatomas are collections of squamous cell debris that form a round, pearly mass. Despite what the name implies, cholesteatomas do not contain any lipid or cholesterol components.

Keratinizing squamous epithelium grows from the tympanic membrane or the auditory canal into the middle ear mucosa or mastoid air cells. Pasted image 20231231112217.png
