Exophytic lesions of the tongue encompass a diverse spectrum of entities. These are most commonly reactive, arising in response to local trauma but can also be neoplastic of epithelial, mesenchymal or miscellaneous origin. In most cases, the microscopic examination is likely to provide a straightforward diagnosis. However, some cases can still raise microscopic diagnostic dilemmas, such as conditions that mimic malignancies, benign tumors with overlapping features and anecdotal lesions. A series of "lumps and bumps" of the tongue are presented together with suggested clues that can assist in reaching a correct diagnosis, emphasizing the importance of the clinico-pathological correlations.
