Exam 12: Benign Nonodontogenic Tumors

A 21-year-old woman went to her dentist because of facial asymmetry. This had occurred gradually over 3 years. The patient has had no symptoms. A diffusely opaque lesion was found in her right maxilla. All lab tests (CBC, alkaline phosphatase, calcium) were within normal limits. Biopsy was interpreted as a fibro-osseous lesion. She most likely has:

The ossifying fibroma is characterized clinically by:

A 20-year-old patient presents with increased mobility of only anterior mandibular teeth. Extensive loss of alveolar bone is noted radiographically without evidence of significant periodontal disease. The lesion is lucent with sharp margins. This would suggest which of the following?

Patients with central giant cell granulomas typically have which of the following abnormal laboratory findings?

Which of the following could be classified as a benign fibro-osseous lesion?

Serum calcium would be significantly elevated in which of the following?

Which of the following conditions significantly increases a patient's risk for development of adenocarcinoma of the colon?

A 22-year-old woman has "spontaneous" loss of teeth nos. 28, 29, and 30. She has no periodontal pockets associated with the remainder of her teeth. Panoramic radiograph shows a sharply defined radiolucency in the area of tooth loss as well as another lucency in the body of her left mandible. She may have which of the following?

Ubiquitous dendritic cells, found within mucosa and epidermis and having the function of processing foreign antigens and presenting relevant determinants to immunocompetent cells are known as:

A biopsy of a periapical lesion associated with a vital tooth showed CD1a-positive round pale cells and many eosinophils. The diagnosis is:

A 17-year-old patient had asymptomatic sharply defined "punched out" radiolucencies of the body of the mandible subjacent to vital molar teeth. She also had related lucencies in the cranium. Microscopically, the lesions consisted predominantly of round cells with scattered eosinophils. This is descriptive of:

Ossifying fibroma:

Which of the following lesions would most likely present radiographically as "floating teeth" in the jaw?

A 15-year-old patient was found to have a 2 ´ 3 cm multiloculated radiolucent lesion of his mandible. At the time of surgery, a solid, bloody lesion was removed. Histologically, it was composed of benign-appearing fibroblasts and multinucleated giant cells. This is most likely which of the following?

A 16-year-old patient is found to have several well-defined radiopacities in his jaws. The patient is asymptomatic and teeth are vital. These lesions could be which of the following?

The combination of multiple asymptomatic radiopaque jaw lesions with supernumerary teeth and intestinal polyps is indicative of:

A 33-year-old patient presents with a 1 ´ 2 cm swelling of the right side of his neck. All of the following might be considered in a clinical differential diagnosis except:

All the following are components of McCune-Albright syndrome except:
