From the Guidelines
The correct answer is A. Parotid gland, as approximately 70% of salivary gland tumors arise from this site. Tumors most commonly occur in the parotid gland among all salivary glands, accounting for about 70% of all major salivary gland tumors 1. This high incidence is likely related to the parotid gland being one of the major salivary glands. While the exact reason for this high incidence is not specified, the parotid gland is considered a common site for tumor formation. Some key points to consider include:
- The parotid gland is the most common site for salivary gland tumors, with about 70% of cases occurring in this gland 1.
- The submandibular gland is another site where salivary gland tumors can occur, although it is less common than the parotid gland.
- Tumors of the minor salivary glands, including the sublingual gland, are relatively rare compared to those occurring in the major salivary glands. The high incidence of tumors in the parotid gland highlights the importance of considering this site when evaluating salivary gland tumors, as stated in the study published in the Journal of the American College of Radiology 1.
From the Research
Salivary Gland Tumors
- The most common salivary gland tumor is pleomorphic adenoma, which is a benign neoplasm 2, 3, 4.
- Pleomorphic adenoma is found mostly in the parotid gland, particularly in middle-aged women 2.
- The parotid gland is the most common site for salivary gland tumors, including malignant tumors 3, 5.
Tumor Location
- The parotid gland is the most common location for pleomorphic adenoma, accounting for the majority of cases 2, 3, 4.
- The submandibular gland is also a possible location for salivary gland tumors, but it is less common than the parotid gland 3, 5.
- The submental and sublingual glands are not commonly mentioned as locations for salivary gland tumors in the provided studies.
