a benign growth of skin in an abnormal location such as the middle ear or petrous apex
a benign skin tumor, usually occurring in the middle ear and mastoid spaces
a benign tumor that originated from epithelial cells from the tympanic membrane when it perforated with an ear infection
a collection of viable and desquamated squamous epithelium in the middle ear or mastoid air spaces, which are normally lined only by mucous membrane
a common additional finding along with chronic otitis and mastoiditis
a cyst or sac of skin that is growing backwards behind your eardrum into the middle ear and mastoid
a developmental collection of tissue in the middle ear
a form of epidermoid cyst

a greasylooking mass or accumulationof debris that is seen in a retraction pocket or perforation
a growth that occurs in the middle ear behind the eardrum
a hamartomatous- like, keratin-producing squamous epithelial lesion that is constructed very much like an onion, in layers
a mass of tissue which develops in the middle ear or in the eardrum
an abnormal skin growth in the middle ear behind the eardrum
a sac of skin that arises off the eardrum and erodes into the middle ear and mastoid bone
a skin cyst that, as it grows, can destroy bone and lead to significant complications
a skin growth that occurs behind the eardrum
a skin-lined cyst or pouch that begins as a perforation of the eardrum
a skin sac that grows back into the middle ear or mastoid from the eardrum, creating a mass of skin and debris that keeps getting larger and larger over time, destroying anything in its path
a slow-growing mass that may erode adjacent structures including the middle ear bones and the bone surrounding the ear next to the brain
An abnormal accumulation and pocketing of dead cells in the eardrum, which can often be surgically repaired.
Skin (epithelium) growing in areas it does not belong, can be destructive due to enzymes produced by the skin and pressure necrosis. Commonly used to refer to skin growing in the middle ear and mastoid, causing significant infection and erosion.
accumulation of dead cells in the middle ear caused by repeated middle ear infections.
a skin like tumor of the middle ear
A benign expanding mass which can form in the middle ear cavity. It is made up of skin and cholesterol crystals. The mass can become infected and cause other problems in the middle ear.
(1) A pseudotumor, usually occurring in the middle ear and mastoid. Can be dangerous; highly erosive, and may cause destruction of bone and other tissue. (2) cystic tumor containing epidermal or similar tissues, that is growing in a confined area (such as the middle ear) & frequently constitutes a sequel to chronic otitis media. It may appear as a compact shiny mass.
Cholesteatoma is a destructive and expanding sac in the middle ear and/or mastoid process. There are two types: congenital and acquired. Acquired cholesteatomas can be caused by a tear or retraction of the ear drum.
