Comparação da espessura da perimatriz, de colesteatomas adquiridos, entre pacientes pediátricos e adultos

Abstract: Chol esteatoma may occur either in children as in adults; in children, however, they have a more aggressive and extensive growth. Objective: To compare the thickness of the perimatrix, in µm, between adults (>18 years old) and children cholesteatomas. Study design: transversal cohort. Material and Method: 74 cholesteatomas (35 of children) obtained from othologic surgeries were included, fixed in formol 10%. It was made laminas with HE and Picrossisius, with were studied at the optic microscope. We obtained di… Show more

“…When looking at the hematoxylin-eosin stained specimens in an optical microscope, it was clear that cholesteatomas consist of keratinized squamous stratified epithelium, with four layers identical to those of thin skin (basal, squamous, granulous, and stratum corneum), lying on a bed of connective tissue that contains fibroblasts, lymphocytes, plasmacytes, and e macrophages. These findings were compatible with those of other authors that looked into cholesteatoma histopathology 1 , 4 , 6 . There is some divergence as to the best nomenclature for cholesteatoma epithelium and the connective tissue it lies on.…”
