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 = .006).
The results of this study showed that 16.4% 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.
(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.
These elements can include squamous cells with bacteria from the oral cavity, ciliated respiratory columnar epithelial cells, histiocytes with
anthracotic pigment, chondromyxoid fragments of cartilage, mesothelial cells, mucus, and cuboidal glandular cells of submucosal glands.
If the microscopic examination of LN aspiration specimens revealed
anthracotic pigments, the LN was accepted as
anthracotic lymphadenitis.
There were 47 (52.8%) complicated and 42 (48.2%) simple
anthracotic cases.
Hb and
anthracotic pigment Heart Myoglobin, cytochromes, Hb, lipofuscin, and carotenes?
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.
