A 33-year-old healthy man presented with a 1-year history of a painless, slowly enlarging mass on his tongue. Physical examination showed a firm, 2 × 3-cm nodular lesion in the middle of the tongue, covered by apparently normal mucosa (Figure 1). A biopsy specimen was obtained from the lesion; hematoxylin-eosin (Figure 2) and periodic acid–Schiff (Figure 3) stains were performed.
