Another possibility is the loss of the skin migration property, which causes retainment of desquamated cells. It is often assoc...
متن کاملThe role of S100A1 in external auditory canal cholesteatoma.
S100 proteins were reported to be involved in different biological activities such as transduction of intracellular calcium signalling. It has been reported that each member of the S100 protein family exhibits a distinct tissue-specific pattern of expression. Furthermore, altered S100 protein expression and function correlate with many diseases. The expression of S100A1 was reported to be incre...
متن کاملClassification of External Auditory Canal Cholesteatoma by Computed Tomography
OBJECTIVES We propose here a classification system for external auditory canal cholesteatoma (EACC). We classified the EACC by the computed tomography findings and clinical findings of the patients, and we evaluated the EACC characteristics by the proposed staging system. METHODS Stage classification was done according to the results of temporal bone computed tomography and the clinical findi...
متن کاملCholesteatoma of the External Auditory Canal: A Case Report
