Summary
Warthin tumor, a benign salivary gland neoplasm, rarely occurs in the submandibular gland. This case highlights its unusual presentation and emphasizes accurate diagnosis to avoid misinterpretation of its origin.
Area of Science:
- Head and Neck Surgery
- Oral and Maxillofacial Pathology
- Oncology
Background:
- Warthin tumor, also known as papillary cystadenoma lymphomatosum, is a benign salivary gland neoplasm.
- It predominantly affects the parotid gland and periparotid lymph nodes, with etiopathogenesis linked to tobacco smoke.
- The tumor is believed to arise from heterotopic salivary gland tissues or via a significant lymphoid response.
Observation:
- A rare case of Warthin tumor presented as an asymptomatic, nodular mass near the submandibular salivary gland in a 72-year-old male.
- Initial clinical diagnosis suggested cervical lymphadenopathy.
- The lesion was surgically excised for histopathological examination.
Findings:
- Histopathological analysis confirmed the presence of a benign neoplasm composed of epithelial and lymphoid components.
- The findings were consistent with Warthin tumor originating from the submandibular salivary gland.
- This represents an uncommon site of origin for Warthin tumor.
Implications:
- Warthin tumors originating in the submandibular gland are rare and require careful consideration.
- Accurate histopathological diagnosis is crucial to differentiate from other neck masses and avoid misattributing the origin to the parotid gland.
- Awareness of this rare presentation aids clinicians in accurate diagnosis and management of salivary gland neoplasms.
