Primary salivary gland tumors of the lung: Two cases date report and literature review.
2021
Abstract Background Primary salivary gland-type tumors of the lung (PSGTTL) is a rare intrathoracic malignant tumor that accounts for all lungs Purpose To introduce two case reports of primary lung salivary gland tumors, and highlight their diagnosis and treatment challenges. Case report The first case was a 30-year-old female, who complained of repeated coughing and dyspnea for 1 year and worsening for 2 days. Chest CT and bronchoscopy showed new organisms in the lower part of the trachea, that the bronchus obstruction accounted for 70%. The biopsy histology revealed a adenoid cystic carcinoma. She underwent extensive surgical resection and multiple radiotherapy, and She is recovering well from follow-up. The second case was a 70-year-old man, who complained of intermittent sputum blood for 2 years, worsening hemoptysis and chest tightness for 3 months. The new organisms was found in the upper trachea from Chest CT and bronchoscopy, and histological biopsy was used to diagnose epithelial myoepithelial carcinoma. He underwent two bronchoscopy thermal ablation treatments. The follow-up is currently in good condition. Conclusion Primary lung salivary gland tumors are considered to be rare malignant tumors in the lungs. Early detection is advocated as late presentation with advanced tumour presents diagnostic and therapeutic challenges.
