What is the most common site for oral salivary gland NEOPLASMS (tumors)?
Show answer and explanation
Correct answer: A. Parotid gland
A) Parotid gland — CORRECT.
The parotid gland is where approximately 70-80% of all salivary gland tumors originate. Of parotid tumors, ~80% are benign (pleomorphic adenoma is most common). The rule of 80s: 80% of all salivary tumors are in the parotid; 80% of parotid tumors are benign.
B) Submandibular: Second most common site; higher percentage are malignant (~50%) compared to parotid.
C) Sublingual: Least common major gland site; highest percentage of malignancy (~80%).
D) Minor salivary glands: Important site (especially hard palate) but total volume of tumors less than parotid.
