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

Step 1: Understanding Kuttner Tumor.
Kuttner tumor is a chronic inflammatory condition of the submandibular salivary gland.
It presents as a firm enlargement that may clinically mimic a neoplasm.
Step 2: Nature of the Lesion.
It is not a true tumor but a benign inflammatory enlargement.
Histologically, it shows chronic sclerosing sialadenitis with fibrosis and lymphocytic infiltration.
It is therefore referred to as sialometaplasia of the submandibular gland.
Step 3: Elimination of Other Options.
Adenoid cystic carcinoma is a malignant salivary gland tumor.
Lymphoepithelioma is a malignant epithelial tumor with lymphoid stroma.
Myoepithelioma is a benign salivary gland neoplasm arising from myoepithelial cells.
Kuttner tumor is inflammatory, not neoplastic.
Step 4: Conclusion.
Hence, Kuttner tumor is also known as sialometaplasia of the submandibular salivary gland.
