“…A study conducted in Turkey indicates that exposure to polyvinyl chloride dust increases the rate of pathology detection in HRCT by 4.2 times. Unlike irregular/linear opacity and emphysema, round opacity, ground glass pattern and inhomogeneous attenuation were detected only in the PVC exposure group [8].…”

Polyvinyl chloride is a widely used synthetic plastic polymer worldwide. Today, it is used in many areas, such as health, electricity, electronics, and construction, especially in the building sector. It is known to have many harms to human health. Our case is a 39-year-old male patient who has been working in the plastics industry for 16 years. The patient, who was diagnosed with a gastric neuroendocrine tumor while working, applied to us to investigate the relationship between his tumor and work. Although a clear relationship could not be established, it was found that he had pneumoconiosis during the examination. It was thought this was due to the polyvinyl chloride he had been exposed to for years. As a result, pneumoconiosis can also be seen in people working in the thermoplastic industry, apart from classical pneumoconiosis-forming dust such as silica, silicate and coal. It is very important to detect these patients early with screening and prevent exposure.

Background Although some adverse health effects of exposure to polyvinyl chloride (PVC) are well known, there is limited evidence of its effects on the respiratory system. AimsTo assess the pulmonary effects of exposure to PVC with high-resolution computed tomography (HRCT). MethodsWorkers and administrative staff of two PVC production plants completed questionnaires and went through pulmonary function testing and HRCT. Analysis of PVC dust in the work environment was performed by the Directorate of Occupational Health and Safety. ResultsIn total, 104 PVC-exposed workers and 43 administrative controls participated. HRCT revealed pleural and/or parenchymal changes in 55% of the exposed subjects. Pleural thickening was detected in 14 subjects, 13 of whom were in the exposed group (P < 0.05). Isolated pleural thickening without parenchymal involvement was present in seven workers, who were all in the exposed group (P < 0.05). Pleural thickening was frequently bilateral and localized to the parietal and visceral pleura. Round opacities, heterogeneous attenuation and ground-glass opacities were only detected in the exposed group (P < 0.05). Exposure to dust increased the risk of findings on HRCT (odds ratio (OR) 4.2, P < 0.05). There were no correlations between pulmonary function tests or respiratory symptoms and HRCT findings. HRCT changes were more common in subjects with forced mid-expiratory flow (FEF 25-75 ) < 50% (P < 0.001).Conclusions This study found that exposure to PVC dust, at levels below the legal limit for respirable particulate matter, was associated with parenchymal changes and pleural thickening on HRCT.
