[New immunobiologic trends concerning etiopathogenicity of cholesteatoma].
After an epoch in which was pretended to explain the etiopathogenetic phenomena observed in Cholesteatoma through enzymatic studies, nowadays other investigations focus the topic in the possible presence of immunobiologic alterations at cellular level, so the research work is directed to the occurrence, distribution and activity of several growth factors and leukins. In this paper the AA. made a perusal of the new acquisitions and devote themselves to two important aspects of the cholesteatoma: the biologic behaviour of the squamous cell epithelia with an uncontrolled growth and to the immunobiologic mechanisms responsible for the bone resorption.
