Sumario:BACKGROUND: There is little detailed information regarding benign asbestos pleural effusion (BAPE). It is frequently misdiagnosed because of lack of a standardized diagnostic approach and criteria. The present study aimed to better characterize BAPE and outline a diagnostic approach for this disease. METHODS: Complete clinical data of 11 consecutive patients with BAPE were prospectively collected and analysed. A multidisciplinary team (MDT) was involved in discussing the suspected cases of BAPE. The team was comprised of thoracic physicians, radiologists and pathologists. A multidisciplinary practical diagnostic approach for BAPE was introduced. RESULTS: Six patients had respiratory symptoms, but another 5 were asymptomatic. All the patients had an asbestos exposure and the median duration was 23.9 years (rang, 12–36 years). The median level of lactate dehydrogenase (LDH), adenosine deaminase (ADA), proteins and carcinoembryonic antigen (CEA) in the pleural fluid (PF) were 221.4 U/L (range, 189.8–11,325 U/L), 21 U/L (rang, 14–247 U/L), 48.3 g/dL (range, 35.2–53.2 g/dL) and 3.46 mg/mL (range, 0.84–4.54 mg/mL), respectively. Five patients had pleural plaques, 2 had diffuse pleural thickening (DPT), 1 had asbestosis, and 1 had round atelectasis. The pleural biopsy specimens showed a benign fibrotic pleura in all case. The symptoms and pleural pulmonary radiologic findings remained stable during the follow-up. CONCLUSIONS: BAPE is diagnosed by exclusion. A suspected diagnosis of BAPE with an asbestos exposure should be considered, especially with the presence of pleural plaques, and/or DPT, and rounded atelectasis. The MDT-based diagnostic approach may reduce misdiagnosis.
