Abstract:
A 56-year-old man was point out chest abnormal shadow in the left lung by chest X-ray for routine follow-up of diabetes. Chest computed tomography (CT) revealed emphysematous changes in the bilateral lung, and showed an approximately 23 x 20 mm tumor in the giant bulla of the left upper lobe. Left S(1+2) segmentectomy was performed as the diagnosis of adenocarcinoma was established by intra-operative biopsy. The lesion was diagnosed as poorly differentiated adenocarcinoma (pT1N0M0P0D0PM0E0, stage IA). The frequency of lung cancer within a bulla is reported as high as 14-29% in Japan. Therefore, it is thought to be necessary that the pulmonary bullous lesion must be followed-up for a long period because of the possibility of development of malignancy.

Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
