Pneumoconiosis in coal workers is seen as small nodular aggregations of anthracotic macrophages in the collagen network, which are known as coal macules, with larger aggregations known as coal nodules/mass with or without fibrosis. These are usually seen around the initial site of coal dust accumulation that is the upper regions around respiratory bronchioles; however, in our case the anthracotic mass is present in the anterior basal segment of the lower lobe of the left lung. Although coal workers’ pneumoconiosis is a form of pneumoconiosis that is a common affliction of coal workers and/or chronic smokers. In our patient, prior exposure to biomass fuel exhaust seems to be the only risk factor. We present the case of an 80-year-old man presenting with fever and cough of 4 months’ duration. On evaluation, he was found to have a well-defined mass lesion in the anterior basal segment of the lower lobe of the left lung, which on core biopsy revealed features consistent with an anthracotic mass.
