Background: Pneumoconiosis is common among those who exposured to massive coal dust. The patient with pneumoconiosis are apt to co-morbid with non-tuberculosis mycobacteria infection. We can find prominent process of liquefactive necrosis of progressive massive fibrosis (PMF) from a coal briquettes manufacture factory worker. Methods: 73 years old male worked for a coal briquettes manufacture factory for 20 years, and retired. A ILO classification of his chest X ray graph was (2/3, p/q, 6 lung zone, em, tbi, id B). He has complaint melanoptysis since several months. The serial computed tomograph and sputum analysis were followed. Results: With increased black colored sputum, an air-fluid level was formed at the PMF at right upper lung field from Apr 05 2013. Black colored secretion was drained from whole the bronchus under bronchocsopy at Apr 02 2013. M. Intracellulare was identified at sputum & BAL fluid AFB. Finally, a cavitary lesion remained. Another air-fluid level was shown at the small sized PMF at left middle lung field from Jul 31 2013. We can show those serial radiological and biological findings and while follow up of patients with complicated pneumoconiosis. Conclusions: Aspergilluma is apt to be followed by a cavitary lung lesion. Therefore, those patients with PMF necrosis might have more poor prognosis due to a massive hemoptysis by angiogenesis of lung vasculatures. To prevent fatal events, further evaluation should be followed NTM related liquefactive necrosis of PMF.
