Question

Kuttner tumor, which presents as a benign inflammatory enlargement of the submandibular salivary gland, is also known as:

• A. Sialometaplasia of the submandibular salivary gland
• B. Adenoid cystic carcinoma of the submandibular salivary gland
• C. Lymphoepithelioma of the submandibular salivary gland
• D. Myoepithelioma of the submandibular salivary gland

Hint:

Kuttner tumor = Chronic sclerosing sialadenitis of the submandibular gland (benign inflammatory enlargement).

Answer 1

The Correct Option is A

The question is asking for another name for Kuttner tumor, which is characterized as a benign inflammatory enlargement of the submandibular salivary gland.

Let's evaluate the options:

1. Sialometaplasia of the submandibular salivary gland: Sialometaplasia is a descriptive term for a condition where there is metaplasia (change of tissue type) affecting salivary glands, often leading to swelling and inflammation. It matches the description of Kuttner tumor as a benign inflammatory condition.
2. Adenoid cystic carcinoma of the submandibular salivary gland: This is a malignant tumor, known for its potential to spread and has a completely different pathological background compared to benign conditions like Kuttner tumor.
3. Lymphoepithelioma of the submandibular salivary gland: This term typically describes a specific type of tumor chiefly linked with the nasopharynx, not common in the salivary glands, and usually represents malignancy when present.
4. Myoepithelioma of the submandibular salivary gland: This is a benign neoplasm primarily composed of myoepithelial cells. It does not align with the inflammatory nature of Kuttner tumor.

The most suitable option, given the description of Kuttner tumor as a benign inflammatory enlargement of the submandibular salivary gland, is Sialometaplasia of the submandibular salivary gland. This term correctly reflects the subject condition in terms of its benign and inflammatory nature.
