title: [21-year-old man with squamous cell carcinoma of the lung].
abstract: Lung cancer among people in their twenties is rare and accounts for only 0.1-0.4% of all cases. We describe a case of squamous cell carcinoma of the lung in a 21-year-old man. The otherwise healthy patient presented with a 1 month history of cough. Chest radiography showed a well-defined round mass 5 cm in size in the right lower lobe. Computed tomography also showed a 3 cm hilar lymph node. Bronchoscopy revealed a white polypoid mass obstructing the right basal bronchus. Transbronchial biopsy revealed poorly differentiated squamous cell carcinoma of the lung. Clinical diagnosis was T2N1M0, stage IIB lung cancer. Right lower lobectomy with mediastinal lymph node dissection was performed. Lymph node metastases were proven histologically in the pretracheal, subcarinal, hilar, and intrapulmonary regions. Pathological diagnosis was T2N2M0, stage IIIA lung cancer. Endobronchial and mediastinal lymph node metastases were found 2 months after surgery. He received 3 rounds of chemotherapy with cisplatin and docetaxel and irradiation to the right hilum and mediastinum at a total dose of 60 Gy in 30 fractions. He is alive 6 months after surgery.
