When analyzing bronchial anthracotic patterns in the bronchoscopies performed, the most frequently encountered was the bronchial anthracosis pattern without stenosis (66%); a significantly higher incidence of pulmonary tuberculosis was recorded in patients with stenosis (p = .
4% of bronchial anthracotic patients had tuberculosis; this value was significantly higher than that for the non-bronchial anthracosis control group.
3) In addition, in the elderly, intrathoracic lymph nodes are often anthracotic.
16) In his series of 908 patients, there were 28 cases with anthracofibrosis, only 6 cases with anthracosis, and 43 cases with endobronchial TB without anthracotic pigmentation.
8,9) A case-report study by Amoli, reported on non-smoker
anthracotic cases with prolonged exposure to smoke while baking homemade bread using ground ovens in their homes.
In the present study, tuberculosis was also more prevalent in patients with complicated anthracosis than those with simple
anthracotic change.
Lymph nodes showed lymphoid hyperplasia with reactive nodal architecture and scattered
anthracotic pigment.
For example, in some patients, especially heavy smokers,
anthracotic pigment may be identified along alveolar ducts and respiratory bronchioles; however, there is typically less pigment deposition and less airway fibrosis than in patients with mineral dust-associated bronchiolitic diseases.
The underlying lung parenchyma appears gray-white and usually contains black
anthracotic streaks.
Bronchoscopy showed near-total occlusion of orifice of RML bronchus, which showed markedly inflamed mucosa with
anthracotic pigmentation.
