Malignant Transformation of Warthin Tumor in the Cervical Lymph Node

Area of Science:

• Oncology
• Pathology
• Head and Neck Surgery

Background:

• Warthin tumor is the second most frequent benign salivary gland neoplasm.
• Malignant transformation of Warthin tumor is exceptionally rare.
• Warthin tumors typically occur in the parotid gland.

Observation:

• A case of squamous cell carcinoma arising within a Warthin tumor in a cervical lymph node is presented.
• The patient also had a separate Warthin tumor in the parotid gland.
• This represents a simultaneous occurrence of two rare clinical events.

Findings:

• Demonstrates the possibility of malignant transformation of Warthin tumor.
• Highlights the rare heterotopic occurrence of Warthin tumor in a cervical lymph node.
• Confirms that these two rare entities can coexist.

Implications:

• This case underscores the importance of considering malignant potential even in benign-appearing salivary gland lesions.
• Simultaneous rare events can complicate diagnosis and treatment planning.
• Highlights the need for vigilance in evaluating cervical lymphadenopathy in patients with known Warthin tumors.
