Dear EditorThe oral cavity can be affected by many pathologic conditions of variable cause and significance; however, there are several normal structures and variations of normal structures that may resemble a pathologic state (1,2). Some of them are present in more than 80% of the general population and only require patient guidance (3). In this regard, clinically, normal tongue variations have been mistaken for lesions associated with the Human Papillomavirus (HPV). In both of these cases, the surface of the oral mucosa can be observed in the form of fine bumps that have different manifestations (4,5). The dorsal surface of the tongue is covered with tiny projections known as papillae, which are divided into four types of filiform, fungiform, foliate, and circumvallate papillae (5). These phenomena are different in shape, size, number, and organization according to each mammal species (5,6).
