Summary
A rare intrapulmonary neurilemmoma was diagnosed in a 62-year-old woman after years of follow-up for a lung shadow. Surgical resection confirmed the benign tumor, highlighting its infrequent occurrence in the lung.
Area of Science:
- Thoracic Surgery
- Surgical Pathology
- Pulmonology
Background:
- A 62-year-old woman presented with a lung shadow initially suspected as a hamartoma.
- The lesion demonstrated growth over time and bronchial obstruction.
- Diagnostic workup included imaging, bronchofiberscopy, and biopsy.
Observation:
- Chest X-ray revealed an abnormal shadow in the left middle lung field.
- Bronchofiberscopy showed the tumor occupying the left segmental bronchus (B3).
- Initial diagnosis was suspected neurilemmoma based on biopsy.
Findings:
- Pathohistological examination confirmed a typical neurilemmoma.
- The tumor comprised Antoni type A and Antoni type B cells.
- Left upper lobectomy was performed for treatment.
Implications:
- Intrapulmonary or intrabronchial neurilemmomas are exceedingly rare.
- This case adds to the limited reported instances in Japanese literature.
- Highlights the importance of differential diagnosis for lung tumors, even after initial follow-up.
