Summary
A rare bronchial squamous papilloma in a 70-year-old man was resected, but squamous cell carcinoma developed nearby. Electrosurgical snare is recommended over YAG laser for treating these tumors.
Area of Science:
- Pulmonology
- Oncology
- Surgical Pathology
Background:
- Solitary papillomas of the bronchus are rare tumors.
- Malignant transformation of bronchial papillomas is uncommon but documented.
Observation:
- A 70-year-old male presented with cough and sputum, revealing right middle lobe atelectasis on imaging.
- Bronchoscopy identified a polypoid squamous papilloma with atypia.
- Following endoscopic electrosurgical snare resection, a new adjacent mass was detected.
Findings:
- Histopathology confirmed the new mass as squamous cell carcinoma.
- This case highlights a rare instance of malignant progression adjacent to a bronchial papilloma.
- Only three prior reports of malignant change in Japanese bronchial papillomas exist.
Implications:
- Early detection and complete resection are crucial for managing bronchial papillomas.
- Electrosurgical snare may offer superior visualization and control compared to YAG laser for resection.
- Further research into the malignant potential of bronchial papillomas is warranted.
