1. Whlch of the following lesions extensvie finger like processes into surrounding tissue

A lesion characterized by extensive finger-like (papillary) processes projecting into the surrounding tissue is a papilloma. Its frond-like architecture is the defining feature. [REVIEW: keyed answer 'a' lipoma is incorrect — finger-like papillary projections describe a papilloma (option b), not a lipoma.]

Sample

2. Checking tor visual field is done from e distance of

Visual field testing by confrontation is performed with the examiner at a distance of about 50 cm (half a meter) from the patient. This positioning allows comparison of the patient's field with the examiner's.

Sample

3. The congenltale pullslsa

A congenital pulsatile soft-tissue lesion most consistent with the options is a vascular/muscular tumor; the keyed answer identifies a myoma. [REVIEW: question text is garbled; a congenital pulsatile lesion more typically suggests a vascular lesion such as a hemangioma/AVM rather than a myoma.]

Sample

4. Neuroflbroma

Neurofibroma is typically non-painful, may occur at sites of nerve foramina, and carries a risk (about 15 percent in NF1) of malignant (sarcomatous) transformation. The keyed answer reflects that all these features apply.

Sample

5. Osteoma

Osteoma is a benign bony tumor that is typically attached to the cortical plate, appearing as a dense radiopacity. It is composed of mature compact or cancellous bone.

Sample

6. Palatal tori

Palatal tori are benign bony exostoses that are hereditary, tend to stop growing when somatic growth ceases, and rarely if ever undergo malignant change. The keyed answer reflects that the listed benign features apply.

Sample

7. Osteold osteoma

Osteoid osteoma is a small (usually under 1 cm) benign bone lesion that is characteristically painful (classically relieved by NSAIDs) and shows a radiolucent nidus with a sclerotic rim. The keyed answer reflects that all these features apply.

Sample

8. Pain occurs wlth

Pain is a feature of osteoid osteoma and osteoblastoma (and can occur with some chondral lesions). The keyed answer reflects that pain occurs with these bone-forming tumors. [REVIEW: chondroma is usually painless; osteoid osteoma and osteoblastoma are the classically painful lesions.]

Sample

9. Fibrous dysplasla

Fibrous dysplasia causes facial disfigurement (often with maintained occlusion), can obliterate the maxillary sinus, and weakens bone, lowering its resistance to infection. The keyed answer reflects that these features apply.

Sample

10. Non calclflc central tumors of the law

Non-calcified central jaw tumors/cysts are aspirated to assess their contents; depending on access this is done through intact mucosa or after flap reflection/exposure. The keyed answer reflects that all these aspiration approaches may apply.
