Anitschkow nuclear changes observed in oral smears.

Squamous epithelial cells with nuclear characteristics similar to those of the "Anitschkow myocyte" have been found in smears from the oral cavity. The cells are found in scrapings from the area around the labial fold of the lower lip and are most commonly found in abundance in people with active aphthous ulcers. Electron microscopic study of material from the oral cavity is being undertaken by the ultrastructural section of our department.
