反復性肺炎を呈した気管支炎症性ポリープの1症例

抄録

A 63-year-old man visited our hospital with a complaint of recurrent pneumonia in right upper lobe (S²). Bronchofiberscopy was carried out and a polypoid tumor was detected at the orifice of right B².
The histological examination of biopsy specimens revealed the atypical cell infiltration in the bronchial mucosa. However it was not unclear whether the polypoid tumor was malignant or not. Therefore surgical approach was chosen to obtain the difinite diagnosis and then the right upper lobectomy was performed.
The histopathological study of the ressected lung indicated the inflammatory pseudopolyp.
Inflammatory pseudo-polyp is relatively rare disease in comparison with tumor polyp, and it is quite important to differentiate from malignant tumor.
It might be suggested that the bronchofiberscopy should be performed when a patient has experienced the recurrent pneumonia in the same pulmonary region.
