A 54-year-old

male came to ENT doctor complaining of nasal obstruction and epistaxis. Rhinoscopy

revealed a tumour on the nasal diaphragm. Microscopic examination showed a

neoplasm with an endophytic pattern of growth, forming finger-like projections

in the underlying tissue, consisting of the typical cylindrical epithelium of

airway tract with an increase in the number of cylindrical rows.

Which tumour

corresponds better to the aforementioned clinico-pathologic findings?
