Objective: Describe the clinical and paraclinical characteristics of patients with pleural effusion and identify some factors related to malignant pleural effusion. Methods: Descriptive study, total sample size, obtained 179 pleural effusion patients treated at Thai Nguyen Lung Hospital, from June 2022 to June 2023. Patients were divided into 02 groups of malignant pleural effusion and non-malignant pleural effusion. Results and discussion: Pleural effusion occurred in 66.5% of men, 70.4% ≥50 years old, and 11.2% with a history of pleural effusion. Symptoms of pleuritic chest pain were 86.0%, triple reduction syndrome was 82.1%, and dyspnea was 67.6%. The volume of fluid was average 45.3%, one side 89.4%, yellowish lemon fluid color 72.1%. Cell Block to diagnose malignant pleural effusion accounts for 17.9%. The cause is lung cancer 62.5%.  Adenocarcinoma 78.3%. Factors closely related to malignant pleural effusion are: rapid recovery of effusion, weight loss, fluid quantity and fluid color with p<0.01. Conclusion: Most people experience unilateral pleural effusion, exudate, and yellowish lemon fluid color. The rate of malignant pleural effusion is 17.9%, mainly due to metastatic adenocarcinoma from the lung. Some factors related to malignant pleural effusion include being ≥50 years old, having a history of pleural effusion, weight loss, rapid fluid recovery, large amounts of fluid, and fluid that is often red or pink in color. Cellblock should be prescribed in the setting of pleural effusion.
