Question: 1 / 400

Which of the following characteristics is true about Warthin’s Tumor?

It is malignant

It occurs predominantly in the submandibular gland

It tends to be unilateral

It is composed of lymphoid tissue and ductal epithelium

Warthin's Tumor is indeed characterized as being composed of lymphoid tissue and ductal epithelium. This unique composition is what distinguishes it from other types of tumors. Specifically, Warthin's Tumor, also known as papillary cystadenoma lymphomatosum, typically features a mixture of benign epithelial cells and lymphoid tissue, which often resembles the structure of lymph nodes. This tumor commonly occurs in the parotid gland and is associated with smoking habits.

While it is important to understand the composition of Warthin's Tumor, its non-malignant nature is vital in clinical settings, as it tends to be benign and does not exhibit aggressive features typical of malignant tumors. Furthermore, it is more frequently found bilaterally rather than solely occurring in one gland. This information is crucial for diagnosis and treatment considerations in dental and medical practice.
