Clear cell variant of calcifying epithelial odontogenic tumor without calcification: a rarity

J Contemp Dent Pract. 2014 Jan 1;15(1):119-21. doi: 10.5005/jp-journals-10024-1500.

Abstract

Calcifying epithelial odontogenic tumor (CEOT) is a rare, benign, locally aggressive odontogenic epithelial tumor that affects the jaws. Although there are numerous reports on the variants of CEOT, occurrence of clear cells with complete absence of calcification has been a rarity. Histochemical analysis of tumor cells revealed glycogen granules with PAS staining, with absence of CD 1a staining in clear cells, while the amyloid-like deposit associated with clear cells showed green birefringence with Congo red. We report an unusual variant of CEOT occurring in a 27 years old male patient.
