Asteroid body in the dendrite of the Purkinje cell

Purkinje cell dendrites can swell within the molecular layer. Such changes appear to look like asteroids (hence the name asteroid bodies or dendritic expansions). They are often seen with Purkinje cell cactus formations as aggregated structures that extend like a stretched hand near the eosinophilic portion and are more clearly visualized with silver staining.
