This lesion usually occurs in children or young adults, is often associated with trauma, and may be secondary to slow, minute, recurrent hemorrhages. The most likely diagnosis is:Juvenile ossifying fibromaFibrous dysplasia Periapical cyst Giant cell granuloma Ameloblastic fibroma 6. A 30 y/o patient is found to have a solid jaw lesion. Surgical excision is performed, and representative images are shown for review. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #6 Odontogenic Part 2, Case #6 Odontogenic Part 2, Case #6Clear Cell Odontogenic Carcinoma Adenomatoid Odontogenic TumorAdenoameloblastomaCalcifying Odontogenic Tumor (Pinborg tumor)Renal Cell Carcinoma 7. A 30 y/o patient is found to have a solid jaw lesion. Surgical excision is performed, and representative images are shown for review. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #3 Odontogenic Part 2, Case #3FibrosarcomaAmeloblastic Carcinoma Ameloblastic Fibroma AmeloblastomaMalignant Ameloblastoma 8. Gorlin syndrome (nevoid basal cell nevus syndrome) is associated with which of the following:Paradental cysts Glandular odontogenic cystsMultiple odontogenic keratocysts Multiple calcifying odontogenic cysts Unicystic ameloblastomas 9. Which of the following lesions is associated with McCune Albright Syndrome:Fibrous dysplasia Odontogenic fibroma Ossifying fibroma Cementifying fibroma Ameloblastic fibroma 10. 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:Glandular odontogenic cyst Odontogenic keratocyst Calcifying odontogenic cyst Periapical cyst Dentigerous cyst 11. Which of the following lesions is known as a Pindborg tumor?Adenomatoid odontogenic tumor Calcifying (epithelial) odontogenic tumor Clear cell odontogenic carcinoma Squamous odontogenic tumor Ameloblastoma 12.

A 31 /o male had a destructive jaw lesion which was surgically removed. Representative images from the case are shown. Based on the findings, which of the following is the best diagnosis? Odontogenic Part 2, Case #1 Odontogenic Part 2, Case #1 Odontogenic Part 2, Case #1Malignant AmeloblastomaAdenocarcinomaSquamous cell carcinoma AmeloblastomaAmeloblastic Carcinoma 14. A unicystic ameloblastoma is characterized by all of the following EXCEPT:Infiltrating ameloblastic epithelial islands into the surrounding fibrous wall Single cyst lining Vacuolization of the cytoplasm of the basal cells Palisaded basal cells with polarization of the nuclei Areas resembling stellate reticulum 15. This lesion is characterized by a poorly differentiated conglomeration of dentin, cementum, and enamel. There are usually found in the first two decades of life. The best diagnosis is:Ossifying fibroma Fibrous dysplasia Compound odontoma Complex odontoma Ameloblastic odontoma Loading...
