Sumario:RATIONALE: Tongue metastasis from lung cancer is extremely rare, and the prognosis of these patients is rather poor. PATIENT CONCERS: A 56-year-old man was found a 4-cm cavity lesion in the left upper lobe, which was initially misdiagnosed as tuberculosis. DIAGNOSES: A case of lung squamous cell carcinoma that metastasized to the base of a patient's tongue. INTERVATIONS: We send the biopsy of the lung and the tongue lesions for gene sequencing. OUTCOMES: He received systemic chemotherapy, but continued to have pain at the base of his tongue and died 7 months later. LESSONS: From sequencing data, mutations in KRAS proto-oncogene, GTPase (KRAS), phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and tumor protein p53 (TP53) were found in the tumor biopsy of the patient. All of these were indicators of poor prognosis.
