[A case of a slow-growing, non-mucin-producing bronchioloalveolar carcinoma with a 9-year clinical history before thoracoscopic surgery].
A 73-year-old woman was followed up with high-resolution computed tomography (HRCT) from 2000 through 2002 because an area of ground-glass opacity in area S1 + 2 of the left upper lobe was found on HRCT in August 2000. The opacity was present on ordinary CT scans obtained in 1993, but had not been recognized. Thoracoscopic partial resection of the left lung was performed on October 8, 2002. Pathologic examination of the resected specimen showed localized bronchioloalveolar carcinoma (Noguchi's type B). Tumor doubling time was 1718 days from 1993 to August 2000 and 273 days from August 2000 through 2002. This case of adenocarcinoma with bronchioloalveolar growth was characterized by initial slow growth followed by accelerated growth, no mucin production, and a long interval from the detection of opacity to surgery.
