Viruses that cause neoplastic transformation of cells are called
- A.
Tranformation viruses
- B.
Oncogenic
- C.
Pathogenic viruses
- D.
Opportunistic
Correct Answer
B. OncogenicExplanation
Oncogenic viruses are viruses that have the ability to cause neoplastic transformation of cells, leading to the development of cancer. These viruses can integrate their genetic material into the host cell's DNA, disrupting normal cell growth and division processes. They can also promote the expression of oncogenes or inhibit tumor suppressor genes, leading to uncontrolled cell proliferation and the formation of tumors. Examples of oncogenic viruses include human papillomavirus (HPV), hepatitis B virus (HBV), and Epstein-Barr virus (EBV). These viruses are considered to be the main etiological agents in certain types of cancers.Rate this question:

Which one of the following is a characteristic of benign tumors?
- A.
Numerous mitotic figures
- B.
Rapid growth
- C.
Slow growth
- D.
Metastasis
Correct Answer
C. Slow growthExplanation
Benign tumors are characterized by slow growth. Unlike malignant tumors, which grow rapidly and can spread to other parts of the body (metastasis), benign tumors grow at a slower pace and do not invade surrounding tissues or spread to other areas. This slow growth is one of the key features that differentiate benign tumors from malignant ones.Rate this question:

Severe epithelial dysplasia may also be called
- A.
Epithelial hyperplasia
- B.
Carcinoma in situ
- C.
Infiltrating carcinoma
- D.
Hyperkeratosis
Correct Answer
B. Carcinoma in situExplanation
Severe epithelial dysplasia refers to a precancerous condition where the cells in the epithelial tissue show abnormal growth and differentiation. It is considered a stage before the development of invasive cancer. Carcinoma in situ is another term used to describe this condition, indicating that the abnormal cells are confined to the epithelial layer without invading deeper tissues. Epithelial hyperplasia refers to excessive growth of epithelial cells, but it is not necessarily a precancerous condition. Infiltrating carcinoma refers to cancer that has invaded surrounding tissues, which is a more advanced stage than severe epithelial dysplasia. Hyperkeratosis, on the other hand, refers to the thickening of the outer layer of the skin and is not directly related to severe epithelial dysplasia or carcinoma in situ.Rate this question:

- A.
Malignant melanoma
- B.
Osteosarcoma
- C.
Squamous cell carcinoma
- D.
Rhabdomyosarcoma
Correct Answer
B. OsteosarcomaExplanation
Osteosarcoma is the correct answer because it is a malignant bone tumor that can cause a characteristic "sunburst" pattern on radiographic examination. This pattern is caused by the tumor's aggressive growth and invasion into the surrounding bone, which leads to the formation of spicules or rays radiating outwards from the tumor. This radiographic finding is often seen in osteosarcoma and can help differentiate it from other types of malignant tumors. Malignant melanoma, squamous cell carcinoma, and rhabdomyosarcoma do not typically exhibit this specific radiographic pattern.Rate this question:
