Alveolar cell carcinoma is a specific type of lung cancer. Patients may present with symptoms such as cough, sputum, hemoptysis, emaciation, and bone pain, nausea, and vomiting. On CT, it may appear as corn-like nodules of different sizes in both lungs, and in early stage, it may also appear as ground glass shadows of different sizes, or with solid or insubstantial nodular shadows. The diagnosis is confirmed mainly by bronchoscopy or lung biopsy, which can be performed under bronchoscopy, or by ultrasound-guided puncture for biopsy if the patient has supraclavicular lymph node metastasis. If the patient’s pathological type is clear, immunohistochemistry is also performed, or genotype is performed, and tests for ALK, EGFR and ROS1 are done to clarify the next step of treatment. In patients with early stage of ground glass shadow, surgery can also achieve a cure. If the patients are gene-positive and have mutations, they can be treated by corresponding targeted drugs, which can also achieve better treatment results.
