[DNA character of the cholesteatoma].
OBJECTIVE
To compare the DNA character with in cholesteatoma tissues with that in normal skin.


METHODS
DNA content within 25 cholesteatoma tissues and 10 normal postauricular skin was measured with flow cytometry.


RESULTS
The content of cholesteatoma tissues and postauricular skin specimens are a normal euploid. The cell number during S phase of cholesteatoma (10.9 +/- 2.32)% was higher than that in normal skin(7.31 +/- 2.82)%.


CONCLUSIONS
Although the cholesteatoma has a very high proliferating character, the result suggest it isn' t a malignant tumor.
