A 72-years-old male who has been a heavy smoker suffered from pulmonary tuberculosis some thirty years ago and calcified foci were seen in the left upper lobe. A tumor opacity was found in the left upper lobe, and it grew very rapidly. The left upper lobe lobectomy was performed, and the pathlogical-anatomical examinations of the resected specimen revealed the following findings:<BR>1) The rapid increase of the tumor opacity was caused by the activation of dormant tuberculous foci most likely due to the invasion of contiguous tumor in the external side of the tumor, where certain changes might exist due to cancerous bronchial obstruction.<BR>2) Histological type of the tumor was epidermoid carcinoma.<BR>3) It was suspected that the early lymphogenous metastasis of cancer to the regional glands was suppressed by the existence of old glandular tuberculous changes.
