    Which is bilateral tumor of the salivary gland?

    • A. Oncocyte

    • B. Pleomorphic adenoma

    • C. Whartin tumor

    • D. Sjogren syndrome

    Correct Answer
    A. C. Whartin tumor
    Explanation
    A Whartin tumor is a bilateral tumor of the salivary gland. This means that it can occur on both sides of the body, affecting both salivary glands. Oncocyte, Pleomorphic adenoma, and Sjogren syndrome are not specifically associated with bilateral tumors of the salivary gland.

    All are true about high grade mucoepidermoid carcinoma except

    • A. Poor prognosis

    • B. Can metastasis

    • C. Misdiagnosis clinically as sq. c .c .

    • D. Painful sweeling & mucosal ulceration .

    Correct Answer
    A. C. Misdiagnosis clinically as sq. c .c .
    Explanation
    High grade mucoepidermoid carcinoma is a malignant tumor that arises from the salivary glands. It is characterized by a poor prognosis and the ability to metastasize to other parts of the body. It typically presents with painful swelling and mucosal ulceration. However, it is not commonly misdiagnosed clinically as squamous cell carcinoma (sq. c .c).

    Which of the following is the most common malignant  salivary gland tumor?

    • A. mucoepidermoid carcinoma .

    • B. Pleomorphic adenoma .

    • C. Adenoid cystic carcinoma.

    • D. Acinic cell carcinoma

    Correct Answer
    A. A. mucoepidermoid carcinoma .
    Explanation
    Mucoepidermoid carcinoma is the most common malignant salivary gland tumor. This type of tumor is characterized by a mixture of mucous-secreting cells and epidermoid cells. It can occur in both major and minor salivary glands and is typically low-grade, but can also be high-grade. Mucoepidermoid carcinoma often presents as a painless mass and can cause facial nerve paralysis if it involves the facial nerve. Treatment usually involves surgical removal of the tumor, with or without radiation therapy depending on the grade and stage of the tumor.

    The incidence of S.G tumors in minor S.G is :

    • A. Buccal mucosa followed by palate .

    • B. Palate followed by upper lip.

    • C. Upper lip followed by buccal mucosa.

    • D. Palate followed by lower lip .

    Correct Answer
    A. B. Palate followed by upper lip.
    Explanation
    The correct answer is B. Palate followed by upper lip. This means that the incidence of S.G tumors in minor S.G is highest in the palate and then followed by the upper lip.

    Non epithelium tumor in salivary gland

    • Hamangioma

    • B. Pleomorphic adenoma .

    • C. Mucoepidermoid carcinoma .

    • D. Monomorphic adenoma .

    Correct Answer
    A. Hamangioma
    Explanation
    A hemangioma is a non-epithelial tumor that can occur in the salivary gland. It is a benign tumor made up of blood vessels. This tumor is not cancerous and usually does not cause any symptoms or complications. It can be treated if necessary, but often does not require any treatment.

    Rate this question:

  • 7. 

    Acinic cell adenocarcinoma is common in?

    • A. Submandibular gland.

    • B. Minor salivary gland of palate .

    • C. Sublingual gland .

    • D. Parotid gland

    Correct Answer
    A. D. Parotid gland
    Explanation
    Acinic cell adenocarcinoma is a type of cancer that commonly occurs in the parotid gland. The parotid gland is the largest salivary gland located in front of the ear, and it is responsible for producing saliva. This type of adenocarcinoma specifically affects the acinar cells, which are responsible for producing and secreting saliva. Therefore, the correct answer is D. Parotid gland.

    When bilateral tumor occur metachronous this means?

    • A. Occurring at tha same gland .

    • B. Occuring at the same time

    • C. Occurring at the different time

    • D. Occurring at the different gland

    Correct Answer
    A. C. Occurring at the different time
    Explanation
    The correct answer is C. Occurring at the different time. Bilateral tumor refers to the presence of tumors in both glands or organs. When the tumors occur metachronously, it means that they develop at different times. This is in contrast to synchronous tumors, which occur at the same time. Therefore, option C accurately describes the occurrence of bilateral tumors at different time intervals.

    Warthins tumor is almost exclusive seen in?

    • A. Minor salivary gland of palate

    • B. Submandibular gland

    • C. Sublingual gland

    • D. Parotid gland

    Correct Answer
    A. D. Parotid gland
    Explanation
    Warthin's tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor that is almost exclusively seen in the parotid gland. It is the second most common tumor of the parotid gland, accounting for about 10% of all parotid gland tumors. This tumor typically presents as a painless, slow-growing mass in the parotid gland, most commonly in older males. It is characterized by cystic spaces lined by oncocytic epithelial cells and lymphoid tissue. Although it can occur in other salivary glands, it is predominantly found in the parotid gland.

    Rate this question:

  • 10. 

    The most accepted theory on pathogenisis of warthin tumor is?

    • A. Smoking

    • B. EBV

    • C. Heterotopic salivary gland tissue found within parotid lymph node

    • D. Proliferation of salivary epithelium associated with lymphoid tissue formation

    Correct Answer
    A. D. Proliferation of salivary epithelium associated with lymphoid tissue formation
    Explanation
    The correct answer is D. Proliferation of salivary epithelium associated with lymphoid tissue formation. Warthin tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor that arises from the salivary glands. It is characterized by the proliferation of salivary epithelium along with the formation of lymphoid tissue. This theory suggests that the tumor develops from the metaplastic transformation of the salivary duct epithelium, which then undergoes proliferation and forms cystic spaces lined by epithelial cells. The presence of lymphoid tissue within the tumor is a key feature and supports this theory. Smoking and EBV have been proposed as possible risk factors, but they are not considered the primary pathogenesis of Warthin tumor.
