Rushton bodies: an update.

Rushton bodies are peculiar, eosinophilic, linear, curved or straight, polycyclic, glassy structures occurring with variable frequency in the epithelial lining of odontogenic cysts, whose presence occasionally contributes to the diagnosis. Presence of these structures depends upon the sectioning plane of specimen. They are easily identifiable by their peculiar morphological and staining patterns. There is considerably ambiguity about the nature and epithelial, vascular, odontogenic or keratinous origin of these hyaline bodies. This article highlights the occurrence, light and electron microscopic features and histogenesis of Rushton bodies.
