ABSTRACT

A 67-year-old female was referred to our hospital with an abnormal shadow on chest X-ray. Chest-computed tomography scan revealed a solitary mass shadow in the left lower lobe. As fibrobronchoscopy did not lead to a diagnosis, video-assisted thoracic surgery was performed. Pathological findings showed microabscess, palisading granuloma, and necrotic granulomatous angiitis. The patient was diagnosed with granulomatosis with polyangiitis (GPA). The illness has had an uneventful course without any treatment for more than 1 year. Although cases of solitary lung lesions have rarely been reported, it is important to take GPA into consideration as one of the differential diagnoses for the solitary nodule. This case also demonstrates the diverse disease activity of GPA.
