A case of numerous atypical adenomatous hyperplasia diagnosed by a video-assisted thoracoscopic lung biopsy

摘要

A 46-year-old male was referred to our hospital due to abnormal opacities on chest X-rays. High-resolution CT disclosed focal ground glass attenuation counting up to more than one hundred throughout both lung fields. A wedge-shaped excision by a video-assisted thoracoscopic lung biopsy revealed numerous atypical adenomatous hyperplasia. Although not all the focal ground glass attenuation areas on high-resolution CT were identified as being adenomatous hyperplasia pathologically, so far, a case with adenomatous hyperplasia has not been previously reported.
