Abstract
Background: The etiology of tracheobronchial tree subepithelial pigment spots, detected by endoscopic examination, has not been yet finally established. Some authors attribute them to an active tuberculous process or its outcome; other researchers suggest their association with the professional pathology. Aim: To study the detection rate and etiology of tracheobronchial tree subepithelial pigmented spots within the unspecialized bronchoscopic examination. Materials and methods: A total of 3404 primary therapeutic and diagnostic bronchoscopic data were analyzed. The examinations were conducted using bronchoscopes ВF-1T60 and MAF-TM (Olympus, Japan). Endobronchial photos were performed using a bronchoscope MAF-TM. Results: During the study, the subepithelial pigment spots were detected in 20 (0.59%) cases. In none of these cases, an active tuberculous process or professional pathology was confirmed. Fistulas in projection of subepithelial pigmented spots were found in 3 cases. Conclusions: Detection rate of subepithelial pigmented spots during the non-specialized bronchoscopic procedure is low, less than 1% (0.59% in our study). Clinical, laboratory, instrumental, and anamnestic analyses allowed us to associate the studied pathology with the previous tuberculosis of intrathoracic lymph nodes.
