Lung cancer metastasis to the tongue: Presentation of a case and review of the literature

Background: Oral cavity metastases from lung cancer are exceedingly rare, accounting for only 1% of oral malignancies. We report an 86-year-old female with lung cancer metastasis to the tongue and review existing literature. Results: The patient presented with severe tongue pain. Imaging indicated a necrotic tumoral lesion, confirmed by fine-needle aspiration. She received palliative care involving oral cavity radiotherapy and atezolizumab. Discussion: Tongue metastases are unusual, often mimicking benign lesions, making diagnosis challenging. Treatment options include surgery, radiotherapy, and chemotherapy, but prognosis remains poor. Conclusion: Although rare, tongue metastases from lung cancer pose diagnostic challenges, emphasizing the importance of understanding their clinical characteristics and treatment options.
