Nose, Epithelium - Hyperplasia, Atypical - Gallery

Image of hyperplasia, atypical in the nose, respiratory epithelium from a male B6C3F1/N mouse in a chronic study
Nose, Respiratory epithelium - Hyperplasia, Atypical in a male B6C3F1/N mouse from a chronic study. An abnormal proliferation of basal cells has replaced respiratory epithelium on the turbinate.

Nose, Respiratory epithelium - Hyperplasia, Atypical in a female B6C3F1/N mouse from a chronic study. Proliferation of atypical and poorly organized epithelium is present on the turbinate.
Image of hyperplasia, atypical in the nose, squamous epithelium from a female Osborne Mendel rat in a chronic study
Nose, Squamous epithelium - Hyperplasia, Atypical in a female Osborne Mendel rat from a chronic study. There is some disorganization of the squamous cells and rete peg-like structures.
Image of hyperplasia, atypical in the nose, olfactory epithelium from a male F344/N rat in a chronic study
Nose, Olfactory epithelium - Hyperplasia, Atypical in a male F344/N rat from a chronic study. Nests of proliferative cells (arrows) have extended beneath the basement membrane.

Nose, Olfactory epithelium - Hyperplasia, Atypical in a male F344/N rat from a chronic study. A proliferative band of neuronal-like cells is present beneath the basement membrane, and the overlying olfactory epithelium is disorganized.
