2%) had anthracotic
lesions in the bronchi (case group) and 307 patients (59.
3) Dark anthracotic
pigmentation in the bronchial mucosa is a bronchoscopic finding of pneumoconiosis or evidence of heavy atmospheric soot particles.
Trend analysis indicated that there was an association between anthracosis and indoor smoke exposure due to traditional baking and anthracotic
cases had more life span than indoor smoke exposure.
It is also possible that anthracotic
patients are more prone to TB than TB causing anthracosis.
Because of the lack of a normal communication with the airway, the sequestration typically lacks anthracotic
pigmentation; however, there may be collateral ventilation that may be present congenitally, or as the result of a pathologic connection due to inflammation and infection.
BALT is found in the vicinity of airways, usually contains black anthracotic
pigment, and presents as a nodular collection of chronic inflammatory cells that typically does not surround a vessel but might be seen asymmetrically around a vessel (unlike ACR).
Patients with mild mottled simple anthracotic
change on the bronchi were excluded from bronchial biopsy.
Histopathology revealed chondroid hamartoma with anthracotic
If prominent areas of desquamative interstitial pneumonia-like changes are seen with macrophages that lack anthracotic
smoking pigment, one should consider the possibility of an underlying myelodysplastic syndrome or drug-induced pneumonitis.
The alveolar septa showed necrosis, and the alveolar airspaces contained focal alveolar macrophages, including some with anthracotic
The mediastinal and hilar lymph nodes were prominent and anthracotic
