title: [A case of pulmonary adenocarcinoma of arising from the wall of a giant bulla which disappeared spontaneously].
abstract: In a 53-year-old man, giant bulla was detected on the left side on chest X-ray and mass shadow was demonstrated near the bullae (20 x 10 mm). CT scan did not show a mass shadow and the shadow was diagnosed as scar formed by the bulla wall. Three months later, the bulla had disappeared spontaneously, but an abnormal shadow at the apex of left lung was pointed out. Chest CT findings suggested lung cancer arising from the wall of the collapsed giant bullae and partial resection of the left upper lobe was performed. The postoperative pathological diagnosis was moderately differentiated adenocarcicoma (12 x 5 x 5 mm) arising from pulmonary bullae. It must be noted that occult cancer may exsist at the wall of giant bullae, the surgical procedure involving complete resection of the bullae wall must be selected.
