1. A benign tumor of adipose tissue is called a  

Explanation

A benign tumor of adipose tissue is called a lipoma. Lipomas are non-cancerous growths that develop in the fatty tissue under the skin. They are usually soft to the touch and can occur anywhere on the body where fat is present. Lipomas are generally harmless and do not require treatment unless they cause discomfort or affect the appearance. Schwannomas are tumors that develop from the Schwann cells of the peripheral nerves, hemangiomas are abnormal growths of blood vessels, and lymphangiomas are tumors that form in the lymphatic system.

Hermangiomas are usually present at birth or develop during the first few weeks of life. They are most commonly found on the skin or in the liver, but can also occur in other organs. Hermangiomas are generally harmless and tend to resolve on their own without treatment.

Submit
3. Which one of the following is a characteristic of benign tumors?

Explanation

Benign tumors are characterized by slow growth. Unlike malignant tumors, which grow rapidly, benign tumors tend to grow at a slower pace. This is because benign tumors do not invade surrounding tissues or spread to other parts of the body (metastasis). While they may still cause health issues depending on their location and size, the slow growth of benign tumors is a key characteristic that distinguishes them from malignant tumors.

Submit
4. Which of the following statement about ameloblastomas are true? ameloblastomas

Explanation

Ameloblastomas are benign slow-growing infiltrating tumors that are composed of odontogenic epithelium. They most commonly occur in the mandibular molar ramus area. Therefore, all of the statements about ameloblastomas are true.

Submit
5. A malignant tumor of boneforming tissue is called

Explanation

Osteosarcoma is the correct answer because it refers to a malignant tumor that develops from bone-forming tissue. It is a type of bone cancer that primarily affects children and young adults. Osteosarcoma typically starts in the long bones of the arms or legs, but it can also occur in other bones. It is an aggressive cancer that often requires a combination of surgery, chemotherapy, and radiation therapy for treatment.

Submit
6. A histologic diagnosis of epithelial dysplasia is of concern because the lesion may

Explanation

The histologic diagnosis of epithelial dysplasia is concerning because it indicates abnormal changes in the epithelial cells, which can potentially progress to cancerous changes. This means that the lesion has the potential to become malignant or cancerous. It is important to closely monitor and possibly treat such lesions to prevent the development of cancer.

Submit
7. A malignant tumor of lymphocytes is called

Explanation

A malignant tumor of lymphocytes is called lymphoma. Lymphoma is a type of cancer that affects the lymphatic system, which is a part of the body's immune system. It occurs when lymphocytes, a type of white blood cell, grow and multiply uncontrollably. Lymphoma can develop in various parts of the body, including the lymph nodes, bone marrow, and organs like the spleen and liver. It can present with symptoms such as swollen lymph nodes, fever, weight loss, and fatigue. Treatment options for lymphoma may include chemotherapy, radiation therapy, immunotherapy, and stem cell transplantation.

Submit
8. A white plaque like lesion that cannot be rubbed off or diagnosed as a specific disease is called

Explanation

Leukoplakia is a term used to describe a white plaque-like lesion that cannot be rubbed off or diagnosed as a specific disease. It is a clinical diagnosis that indicates a potentially precancerous condition in the oral cavity. Leukoplakia can occur due to various factors such as chronic irritation, tobacco use, or infection. It is important to monitor and evaluate leukoplakia lesions regularly as they have the potential to progress to oral cancer.

Submit
9. Which of the following is a histologic characteric of squamous cell carcinoma?

Explanation

All of the given options are histologic characteristics of squamous cell carcinoma. Squamous cell carcinoma is known for the invasion of tumor cells into the connective tissue, the presence of pleomorphic epithelial cells, and the formation of keratin pearls. Therefore, the correct answer is "all of the above."

Submit
10. "peripheral" odontogenic tumors are located on the  

Explanation

Peripheral odontogenic tumors are tumors that originate from the tissues surrounding the teeth. The term "peripheral" indicates that these tumors are located outside of the tooth structure itself. Among the given options, the gingiva refers to the gums surrounding the teeth, making it the correct answer for the location of peripheral odontogenic tumors.

Submit
11. Severe epithelial dysplasia may also be called

Explanation

Severe epithelial dysplasia is a pre-cancerous condition where there are abnormal changes in the cells of the epithelium. This condition is often referred to as carcinoma in situ because it resembles cancer cells but has not yet invaded surrounding tissues. It is important to identify and treat severe epithelial dysplasia early to prevent the progression to invasive carcinoma. Epithelial hyperplasia, infiltrating carcinoma, and hyperkeratosis are different conditions that are not synonymous with severe epithelial dysplasia or carcinoma in situ.

Submit
12. Viruses that cause neoplastic transformation of cells are called

Explanation

Viruses that cause neoplastic transformation of cells are called oncogenic viruses. These viruses have the ability to alter the genetic material of host cells, leading to uncontrolled cell growth and the development of tumors. Oncogenic viruses can integrate their genetic material into the host cell's DNA, disrupting normal cellular processes and promoting the formation of cancerous cells. Examples of oncogenic viruses include human papillomavirus (HPV), hepatitis B virus (HBV), and Epstein-Barr virus (EBV). These viruses are known to be directly involved in the development of certain types of cancer.

Submit
13. A small exophytic lesion of the tongue that is the color of normal mucosa and is composed of papillary projectionsarranged in a cauliflower loke appearanceis most likely a

Explanation

A small exophytic lesion of the tongue that is the color of normal mucosa and is composed of papillary projections arranged in a cauliflower-like appearance is most likely a papilloma. This is because papillomas are benign growths that commonly occur on the tongue and have a characteristic appearance with papillary projections. Fibromas are composed of fibrous tissue and do not typically have a cauliflower-like appearance. Neurofibromas are tumors that arise from nerve tissue and would not present with the described appearance. Verrucous carcinoma is a type of cancer that is characterized by a wart-like appearance and is unlikely to be the correct answer given the benign nature of the lesion described.

Submit
14. A benign cementoblastoma can be recognized on xray film because  

Explanation

A benign cementoblastoma can be recognized on an x-ray film because it is well circumscribed, meaning it has a clearly defined border. It is also radiopaque, meaning it appears as a white or light grey area on the x-ray film. Additionally, it is attached to the root of the tooth, which helps distinguish it from other lesions or abnormalities.

Submit
15. Which one of the following lesions characteristically occurs on the gingiva? 

Explanation

A peripheral ossifying fibroma is a benign tumor that typically occurs on the gingiva. It is a reactive lesion that arises from the periodontal ligament or the gingival connective tissue. It presents as a firm, pink, or red mass on the gingiva and can cause local discomfort or bleeding. It is most commonly seen in young adults and can be associated with poor oral hygiene. Treatment involves surgical excision of the lesion.

Submit
16. Which of the folowing is an example of a malignant salivary gland tumor?

Explanation

Adenoid cystic carcinoma is an example of a malignant salivary gland tumor. This type of tumor is characterized by slow growth and the ability to invade nearby tissues and nerves. It is often difficult to completely remove surgically and has a high rate of recurrence. Adenoid cystic carcinoma is known for its tendency to spread along nerves, leading to pain and dysfunction. It can occur in various salivary glands, including the major and minor glands in the head and neck region.

Submit
17. A compound odontoma differs from a complex odontoma in that a compound odontoma

Explanation

A compound odontoma is a type of odontoma that is composed of tooth-like structures. This means that it contains multiple small structures that resemble teeth. This is what sets it apart from a complex odontoma, which does not have these tooth-like structures. The presence of these structures is a characteristic feature of a compound odontoma.

Submit
18. Neoplasia involves

Explanation

Neoplasia refers to the development of a tumor or abnormal growth. It involves an irreversible change in cells, where they start multiplying uncontrollably. This uncontrolled multiplication leads to the formation of a mass or tumor, which can be cancerous or non-cancerous. The cells in neoplasia lose their normal growth control mechanisms, resulting in the uncontrolled growth and division of cells.

Submit
19. A disorder characterised by an overproduction of atypical wbc is called

Explanation

Leukemia is a disorder characterized by the overproduction of atypical white blood cells (WBCs). This condition leads to an abnormal increase in the number of WBCs in the bloodstream. Hemangioma is a benign tumor made up of blood vessels, melanoma is a type of skin cancer, and leukocytosis refers to an elevated WBC count without specifying the abnormality in cell production. Therefore, leukemia is the correct answer as it specifically describes the overproduction of atypical WBCs.

Submit
20. Which one of the following benign tumors is associated with von Recklinghausen disease?

Explanation

Neurofibroma is a benign tumor that is commonly associated with von Recklinghausen disease, also known as neurofibromatosis type 1 (NF1). NF1 is a genetic disorder characterized by the development of multiple neurofibromas, which are tumors that originate from the cells that surround nerves. These tumors can occur anywhere in the body, including the skin, nerves, and other organs. Therefore, neurofibroma is the correct answer as it is specifically linked to von Recklinghausen disease.

Submit
21. Which one of the following malignant tumors has been reported to ashow a characteristic "sunburst" pattern on readiographic examination

Explanation

Osteosarcoma is the correct answer because it is a malignant bone tumor that can exhibit a characteristic "sunburst" pattern on radiographic examination. This pattern is caused by the aggressive growth of the tumor, which leads to the formation of spicules of bone radiating outwards from the central tumor mass. This appearance is often seen in X-rays and is a distinguishing feature of osteosarcoma. Malignant melanoma, squamous cell carcinoma, and rhabdomyosarcoma are not typically associated with this specific radiographic pattern.

Submit
22. The odontogenic tumor that characcteristically presents as a well circumscribed radiolucency located in the anterior maxilla of an adolescent girl is an

Explanation

The correct answer is adenomatoid odontogenic tumor. Adenomatoid odontogenic tumor is an odontogenic tumor that typically occurs in the anterior maxilla of adolescent girls. It is well-circumscribed and appears as a radiolucency on imaging. Ameloblastic fibroma, ameloblastoma, and odontogenic myxoma are other types of odontogenic tumors, but they do not present with the same characteristics as described in the question.

Submit
23. Which of the following are the most common locations for intraoral squamous cell carcinoma?

Explanation

Intraoral squamous cell carcinoma is a type of oral cancer that commonly occurs in certain locations within the mouth. The floor of the mouth, ventrolateral tongue, and soft palate are known to be the most common locations for this type of cancer. These areas have a higher likelihood of developing squamous cell carcinoma due to factors such as exposure to tobacco and alcohol, poor oral hygiene, and chronic irritation. It is important to be aware of these common locations in order to detect and diagnose oral cancer at an early stage.

Submit
24. Malignant melanoma of the oral cavity is rare however the most common introoral location is the

Explanation

Malignant melanoma of the oral cavity is a rare condition. However, when it does occur, the most common locations within the oral cavity are the palate and maxillary gingiva. This means that if a person develops malignant melanoma in their oral cavity, it is more likely to be found in these areas compared to other locations such as the tongue, buccal mucosa, or retromolar area.

Submit
25. All of the following are malignant tumors that arise from squamous epithelium except

Explanation

Adenoid cystic carcinoma is not a malignant tumor that arises from squamous epithelium. It is a rare form of cancer that typically originates in the salivary glands, specifically the major and minor salivary glands. It is characterized by the formation of cysts and the growth of abnormal cells in these glands. Unlike the other options listed, which are all malignant tumors that arise from squamous epithelium, adenoid cystic carcinoma has a different origin and histological features.

Submit
26. The study of tumors is called

Explanation

Oncology is the study of tumors and cancer. It focuses on the diagnosis, treatment, and prevention of cancer. This field involves research, medical procedures, and the development of new therapies to combat cancer. Oncologists are medical professionals who specialize in the treatment of cancer patients. They work closely with other healthcare providers to provide comprehensive care to individuals with cancer.

Submit
27. The most appropriate treatment for epithelial dysplasia is

Explanation

Epithelial dysplasia refers to abnormal changes in the cells of epithelial tissue, which can lead to the development of cancer. The most appropriate treatment for epithelial dysplasia is complete removal, as it ensures that all the abnormal cells are eliminated, reducing the risk of progression to cancer. Observation alone may not be sufficient as it does not address the underlying issue, while chemotherapy and radiation therapy may be used in certain cases, but complete removal is the most effective treatment option.

Submit
28. Osteomas are a component of

Explanation

Gardner syndrome is a genetic disorder characterized by the development of multiple polyps in the colon and rectum, which can eventually lead to colorectal cancer. In addition to these gastrointestinal manifestations, Gardner syndrome can also present with other features including osteomas, which are benign bone tumors. Therefore, osteomas are a component or a characteristic feature of Gardner syndrome.

Submit
29. The cell involved in multiplre myeloma is the

Explanation

The correct answer is plasma cell. Multiple myeloma is a type of cancer that affects plasma cells, which are a type of white blood cell responsible for producing antibodies. In multiple myeloma, abnormal plasma cells multiply uncontrollably in the bone marrow and interfere with the production of normal blood cells. This leads to symptoms such as bone pain, anemia, and increased susceptibility to infections. Therefore, the cell involved in multiple myeloma is the plasma cell.

Submit
30. Verucous carcinoma is differtiated from another squamous cell carcinomas because it

Explanation

Verucous carcinoma is differentiated from other squamous cell carcinomas because it has a better prognosis. Prognosis refers to the likely course and outcome of a disease, and a better prognosis means that the disease is less aggressive and has a higher chance of successful treatment and survival. In the case of verucous carcinoma, it is known to have a slower growth rate, a lower likelihood of metastasis (spreading to other parts of the body), and a higher overall survival rate compared to other squamous cell carcinomas.

Submit
31. All of the following are benign lesion composed of mature compact bone except a(n)

Explanation

All of the options given are benign lesions composed of mature compact bone, except for ossifying fibroma. Ossifying fibroma is a benign tumor of the bone that consists of a mixture of fibrous tissue and calcified material. It is different from the other options, which are non-neoplastic conditions characterized by the formation of excess bone.

Submit
32. Which one of the following is the most common malignant salivery gland tumor in children?

Explanation

Mucoepidermoid carcinoma is the most common malignant salivary gland tumor in children. This tumor is characterized by a mixture of mucous-secreting, squamous, and intermediate cells. It typically presents as a painless mass in the parotid gland and can also occur in other major and minor salivary glands. While adenoid cystic carcinoma and monomorphic adenoma are also salivary gland tumors, they are less common in children. Papillary cystadenoma lymphomatosum is a benign tumor that is commonly known as Warthin tumor and is not malignant.

Submit
33. The most common intraoral location for salivary gland tumors is the

Explanation

Salivary gland tumors can occur in various locations within the oral cavity, but the most common intraoral location is the palate. The palate is the roof of the mouth, and it contains minor salivary glands that can develop tumors. These tumors can be benign or malignant and may present as painless masses or ulcers. The high prevalence of salivary gland tumors in the palate is likely due to the large number of minor salivary glands present in this area.

Submit
34. The odontogenic tumor tha tmost resembles the mesenchyme of the dental follicle histologically is 

Explanation

The odontogenic myxoma is the correct answer because histologically it closely resembles the mesenchyme of the dental follicle. This tumor is characterized by a loose myxoid stroma with scattered spindle-shaped cells. It is often associated with unerupted teeth and can cause expansion of the jawbone. The cementifying fibroma, complex odontoma, and adenomatoid odontogenic tumor have different histological features and do not resemble the dental follicle mesenchyme as closely as the odontogenic myxoma.

Submit
35. Which one of the following malignancies is characterized by monoclonal spike on immunoelectrophoresis

Explanation

Multiple myeloma is characterized by a monoclonal spike on immunoelectrophoresis. This spike represents the abnormal production of a single clone of plasma cells, which produce a specific type of immunoglobulin. This monoclonal spike is a hallmark feature of multiple myeloma and helps in its diagnosis. Metastatic lung carcinoma, lymphoma, and leukemia do not typically exhibit this monoclonal spike on immunoelectrophoresis.

Submit
36. Match the following
Submit
37. The most common malignant soft tissue tumor of the head and neck in children is  

Explanation

Rhabdomyosarcoma is the most common malignant soft tissue tumor in the head and neck region in children. It is a type of cancer that develops from skeletal muscle cells. This tumor is aggressive and can occur in various locations, including the head and neck area. It is more commonly seen in children than in adults. Squamous cell carcinoma, malignant odontogenic tumor, and osteosarcoma are all different types of tumors, but they are not as commonly found in the head and neck region of children as rhabdomyosarcoma.

Submit
38. Your patient a 48yr old black women present with multiple asymptomatic radiopaque massess on the mandible and maxilla.  there is no expansion of bone.  the most likely diagnosis is

Explanation

Florid cemento-osseous dysplasia is the most likely diagnosis in this case. This condition typically affects middle-aged black women and is characterized by multiple radiopaque masses on the mandible and maxilla. Unlike odontomas and cementifying fibromas, there is no expansion of the bone in florid cemento-osseous dysplasia. Additionally, periapical cement-osseous dysplasia usually presents as a single radiolucent lesion near the apex of a tooth, which is not consistent with the findings in this patient.

Submit
39. Which one of the following is the most common odontogenic tumor?

Explanation

Odontomas are the most common type of odontogenic tumor, accounting for approximately 70% of all odontogenic tumors. They are benign tumors composed of dental tissues, such as enamel, dentin, and cementum, and are typically found in the jawbones. Odontomas are usually asymptomatic and are often discovered incidentally on dental radiographs. They are typically slow-growing and do not spread to other parts of the body. 

Submit
40. The most frequent introoral sit for metastatic tumors is

Explanation

The mandible is the correct answer because it is the most common site for metastatic tumors in the oral cavity. Metastatic tumors are cancers that have spread from another part of the body to the oral cavity. The mandible, which is the lower jawbone, is a common site for metastasis due to its rich blood supply and proximity to other structures in the head and neck region. Tumors can easily spread to the mandible through the bloodstream or direct invasion from nearby structures.

Submit
41. Which one of the following malignant tumors may present as diffuse gingival enlargement with persistent bleeding?

Explanation

Metastatic lung carcinoma can present as diffuse gingival enlargement with persistent bleeding. This occurs because cancer cells from the lung can spread to the gums and cause inflammation, leading to gingival enlargement. Additionally, the tumor can disrupt blood vessels in the gums, resulting in persistent bleeding. It is important to consider metastatic lung carcinoma as a possible cause when evaluating patients with these symptoms.
