Peculiarities of proliferative processes in inverted papilloma, carcinoma of nasal cavity and paranasal sinuses

Abstract

The article presents the results of investigation on detection of criterions of cell changing in inverted papilloma and carcinoma of the nasal cavity mucose and paranasal sinuses. Proliferative process in different layers of nasal cavity mucose and paranasal sinuses was examined by immunohistochemical method. It was established that the most important for diagnosis of inverted papilloma is proportion of cells in basal and parabasall layers.
