ABSTRACT
Cholesteatoma is a destructive pathology characterized with progressive
and chronic infiltration of keratinized squamous epithelium that can be
seen the middle ear and mastoid regions of temporal bone. It has serious
intra and extracranial complications which can be difficult to manage.
Embryologic remnants of squamous epithelium, squamous metaplasia of
middle ear epithelium, migration of epidermal cells from external ear canal
and tympanic membrane and cell seeding because of middle ear surgery or
trauma were all stated as causes of cholesteatoma. Cytokeratins are important
markers of cell differentiation. The patterns of cytokeratin expression
correlate well with the state of keratinocyte proliferation, migration and
differentiation. These patterns are known to be affected during the formation
of cholesteatoma. Increasing our knowledge about cytokeratin patterns
may help us understand the unknown formation of cholesteatoma. In
this review article, a literature survey was done about cytokeratin patterns
of cholesteatoma.
