Blue nevus of the oral cavity: An electron microscopic study

The present report deals with the fine structure of a blue nevus of the oral cavity. The ultrastructure of the melanocyte in this lesion is described, and the presence of some hitherto unknown structures, such as a fibrous lamina within the nucleus, cilia, and microtubules, is reported.

Summary:The present report deals with the fine structure of a blue nevus of the oral cavity. The ultrastructure of the melanocyte in this lesion is described, and the presence of some hitherto unknown structures, such as a fibrous lamina within the nucleus, cilia, and microtubules, is reported. The surfaces of the melanocytes possess numerous dendritic pseudopods, containing microtubules, which are thought to act as a cytoskeleton. The surface is further characterized by a rather intense pinocytic activity. The melanocytes are surrounded by a basement membrane, in contrast to the macrophages, which may establish epithelium-like contacts.
