“…Probably, the particles have been previously inhaled, phagocyted by alveolar macrophages, and then transported by the lymphatic system to the nodes, which is in contrast with particles potentially directly released from the needle. This metal particle deposition could be associated with a potential risk of granulomatous inflammatory reaction (13,14). Anthracosis often causes intrapulmonary lymphadenopathy, but rarely mediastinal mass, mediastinal lymphadenopathy, or axillary lymphadenopathy.…”

Background/aim: Enlarged mediastinal lymph nodes can result from serious etiologies including granulomatous disease, neoplasia, etc., and a rare condition called anthracosis . The aim of this study was to determine the incidence of risk factors and the uptake values within the anthracotic lymph nodes.Materials and methods: 106 patients who underwent endobronchial ultrasound transbronchial needle aspiration and were diagnosed as having anthracosis were analyzed retrospectively. Patients with positive confirmation by surgical biopsies or a 1-year follow-up period were enrolled.Results: 201 lymph nodes were sampled from 106 patients. Subcarinal and interlobar lymph nodes were the most commonly affected stations (36.8% and 34.3%, respectively). The mean durations of exposure to biomass and cigarette smoke were 35.5 and 33 years, respectively. The mean maximum standardized uptake value (SUVmax) within the lymph nodes was 4.76. The SUVmax of the patients with associated malignancy was 4.19 and the SUVmax of nonmalignant patients was 5.28. This difference was statistically significant (P = 0.009). Conclusion:These findings suggest that anthracosis also affects the mediastinal and hilar stations; it should be considered in differential diagnosis in patients with mediastinal and hilar lymphadenopathies with intense uptake on positron emission tomography scans, especially when there is a history of exposure to known risk factors.

“…These contaminants are usually external to endoscopy and EUS-FNA devices. However, metal particles from needles have been reported as potential contaminants [4]. We report our cytologic observation of needle/stylet-derived metal contaminants during pancreatic and gastroesophageal EUS-FNA procedures.…”

“…We have excluded these possibilities because we do not use these fixatives or stains in our cytology samples. We considered the possibility of metallic residues dislodged from the surfaces of the stylet and needles during the proce-Acta Cytologica 2020;64:394-396 DOI: 10.1159/000503915 dure because they were similar to the extracellular black particles reported by Gounant et al [4]. The materials most likely represent heavy-metal particles such as nickel, titanium, and stainless steel that shed as a result of friction between the stylet outer diameter and the needle inner diameter.…”

“…We thank Dr Casoni and colleagues for their interest in our recent article published in CHEST (January 2011) 1 on the release of metal particles from ViziShot needles (Olympus Ltd; Tokyo, Japan) used for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA ). We believe that Dr Casoni et al failed to understand why this study was designed.…”
