Abstract | INTRODUCTION: METHODS: RESULTS:
ICAM-1 and ICAM-2 were present in normal skin in microvascular endothelial cells and in intersticial cells of the dermis. Cholesteatoma showed a very important increase of the ICAM-1 expression with comparison to human skin. All infiltrating immune cells showed positive reactions for the antibody. Furthermore, the intensity of the staining of vessels cells was higher than in normal skin. Keratinocytes were only positive if a very heavy infiltrate was present subepidermally. ICAM-2 was present in endothelial and intersticial cells in normal skin and in cholesteatoma. Most of the infiltrating cells in the cholesteatoma stroma showed positive reactions for the anti-ICAM-2 antibody. CONCLUSION: Our results suggest that both ICAM-1 and ICAM-2 play a central role in the regulation of the inflammatory disorders observed in cholesteatoma.
