case_images: Photomicrograph showing odontogenic epithelial island with peripheral ameloblast-like cells (pre-ameloblasts) and centrally stellatereticulum like cells. Also seen is acanthomatous change (squamous metaplasia with keratin pearl formation) within the follicle, which also shows comedo necrosis (H and E, x40 objective)

case_images: This was a case of a 70-year-old male patient who reported to our department with the complaint of rapidly growing painless swelling of the left side of lower jaw with difficulty in chewing, multiple mobile teeth over left side of both jaws and progressive loss of teeth for last 6 months [Figure 8].
