Lung Biopsy Pathology of Five Patients with Chronic Lung Abscess Associated with P. micra

No.	Lesion Site	Biopsy Method	Lung Biopsy Pathology
1	Left upper lung lobe	CT-guided percutaneous lung puncture	Chronic suppurative inflammation of lung tissue
2	Right middle lung lobe	Endobronchial ultrasound-guided transbronchial needle aspiration	Chronic inflammation of lung with cryptogenic organizing pneumonia
3	Left lower lung lobe	CT-guided percutaneous lung puncture	Chronic inflammation of lung tissue with fibrous hyperplasia
4	Right upper lung lobe	CT-guided percutaneous lung puncture	1. (At early onset) lung tissue, with fibrous tissue hyperplasia in the alveolar cavity; 2. (After 8.5 months) lung tissue, interstitial fibrous tissue hyperplasia with multiple inflammatory cell infiltration
5	Left upper lung lobe	CT-guided percutaneous lung puncture Surgical resection	1. Chronic inflammation with fibrous tissue hyperplasia and infiltration of the lymph, plasma cells, and eosinophils, regional necrosis 2. Bronchogenic cyst with chronic suppurative inflammation and the formation of a multifocal abscess
