A case of bronchioloalveolar carcinoma found with an infiltrative shadow, remaining after pneumonia treatment

Abstract

The case was a 55-year-old man. He was hospitalized with pneumonia of the left lower lobe in another hospital in January 2010, and, after one week, showed a pneumonia shadow and the relief of inflammatory symptoms, and was discharged. The infiltrative shadow remained after three months, and so he was introduced to this hospital for close inspection in April. Bronchoscopy showed Papanicolaou examination class V from the left B8a. We performed left lower resection and lymph node dissection in June. The postoperative diagnosis was bronchioloalveolar carcinoma (pT3N0M0 IIB). When a shadow remains after treatment for pneumonia, in pneumonia cases that are not obstructive pneumonitis, neoplastic disease should be considered.
