A 20-year-old man presented with a painless enlargement of the maxillary gingiva with no bone involvement. Microscopic examination with special stains confirmed the diagnosis of a clear cell variant of a calcifying epithelial odontogenic tumor (Pindborg tumor). This is the second reported case of such a variant in an extraosseous location.
