Odontogenic Part 2, Case #4 Odontogenic Part 2, Case #4 Odontogenic Part 2, Case #4 Odontogenic Part 2, Case #4AmeloblastomaMalignant AmeloblastomaAmeloblastic Fibroma Ameloblastic CarcinomaFibrosarcoma 14. This cystic lesion is characterized by a stratified squamous epithelium (at least partially), a well defined basal layer of cuboidal to columnar cells (may resemble ameloblasts), and ghost cells (similar to a pilomatricoma). The best answer is:Odontogenic keratocyst Calcifying odontogenic cyst Periapical cyst Glandular odontogenic cyst Dentigerous cyst 15. Gorlin syndrome (nevoid basal cell nevus syndrome) is associated with which of the following:Multiple calcifying odontogenic cysts Multiple odontogenic keratocysts Glandular odontogenic cystsUnicystic ameloblastomas Paradental cysts Loading...
