Immunobiological Peculiarities of Cholesteatoma in Children: Quantification of Epithelial Proliferation by MIB 1

Abstract: Cholesteatoma in children is characterized by a more extensive and rapid growth in the middle ear and mastoid cavities. The growth characteristics of the cholesteatoma in 20 children were studied using the monoclonal antibody MIB 1, which recognizes a nuclear antigen expressed by cells in the G1, S, and G2/M phases. Specimens of normal adult auditory meatal skin (n = 15) and adult cholesteatoma (n = 15) served as controls. The tissue specimens were prepared for immunohistochemical examination using the alkalin… Show more

“…It is assumed that in pediatric population cholesteatoma possesses higher proliferative potential than in adults [17]. Nevertheless, recently, it has been proven that there is no direct correlation between age and proliferation rate [18].…”

“…Dentre as substâncias utilizadas como marcadores de proliferação celular, existe o Ki-67, que é um antígeno presente no núcleo das células em fase de multiplicação (fases G 1 tardia, S, G 2 e M do ciclo celular). Alguns autores como Bujía et al 10 e Mayot et al 11 observaram um elevado percentual de células Ki-67 positivas na matriz do colesteatoma em relação à epiderme normal, sendo este percentual diverso em diferentes locais de um mesmo caso, dependendo de variáveis como a espessura do epitélio, presença de granulação e maior quantidade de células inflamatórias na perimatriz.…”
