Figure 3

Micrograph H&E @ ×100 showing a section of the nasopharyngeal mass lined by the respiratory-type epithelium with invagination into the stroma, forming glands that have ciliated epithelial lining and outer prominent basement membrane consistent with a respiratory epithelial adenomatoid hamartoma.
