[Solitary papilloma of the lung; report of a case].

ABSTRACT

A 66-year-old woman admitted our hospital due to an abnormal shadow in the right lung field on a routine chest X-ray film. Preoperative diagnosis was not made, we didn't have correct diagnosis of benign or malignancy by intraoperative frozen-section specimen, so segmentectomy without lymph nodes dissection was performed. The histopathological diagnosis was glandular papilloma. A solitary papilloma in the lung field is rare, it is considered to be difficult to differentiate malignancy or benign clinically.
