Abstract:
Synovial sarcoma (SS) is a rare tumor originating from mesenchymal tissue and accounting for approximately 5-10% of all soft tissue sarcomas. A rare case of primary pulmonary SS in an asymptomatic 18-year-old man admitted to our hospital for investigation of a 6 × 6.5 cm, oval-shaped, well-delineated pleural based peripheral mass in the left lower lobe in his thorax CT is presented. Left lower lobectomy was done. Immunohistochemically, tumor cells were positive for cytokeratin, epithelial membrane antigen (EMA), and vimentin so that the histopathological diagnosis was compatible with biphasic spindle cell type SS in the lung.

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.
