Malignant pleural effusion (MPE) denotes an advanced malignant disease process. Most of the MPE are metastatic involvement of the pleura from primary malignancy at lung, breast, and other body sites apart from lymphomas. The diagnosis of MPE has been traditionally made on cytological examination of pleural fluid and/or histological examination of pleural biopsy tissue that still remains the initial approach in these cases. There has been tremendous advancement in the diagnosis of MPE now a day with techniques i.e. characteristic Ultrasound and computed tomography features, image guided biopsies, fluorodeoxyglucose-positron emission tomography imaging, thoracoscopy with direct biopsy under vision, tumor marker studies and immunocytochemical analysis etc., that have made possible an early diagnosis of MPE. The management of MPE still remains a challenge to pulmonologist and oncologist. Despite having various modalities with better tolerance such as pleurodesis and indwelling pleural catheters etc., for long-term control, all the management approaches remain palliative to improve the quality of life and reduce symptoms. While choosing an appropriate management intervention, one should consider the clinical status of the patient, life expectancy, overall cost, availability and comparative institutional outcomes, etc. [ABSTRACT FROM AUTHOR]

Background: Medical thoracoscopy is a minimally invasive procedure used in diagnostic and therapeutic applications for pleural diseases. In this study, we describe our experience in the outcome and analysis of thoracoscopy in undiagnosed pleural effusion presenting to our center. Materials and Methods: This is a prospective study conducted over last 2 years. We performed thoracoscopy in 129 cases of undiagnosed exudative pleural effusions using rigid thoracoscope. Clinical, radiological, cyto and histopathological data of the patients were collected prospectively and analyzed. Results: The overall diagnostic yield of thoracoscopic pleural biopsy was 110/129 (85.2%) in patients with undiagnosed pleural effusion, and 19/129 (14.8%) patients remained unexplained. Histopathological diagnosis confirmed malignancy in 66.4% patients (both primary and metastatic pleural carcinoma), tuberculosis in 28.2%, others including parapneumonic effusion in 4 cases followed by multiple myeloma, lupus pleuritis, and pulmonary langerhans cell histiocytosis in one case each. Procedure-related mortality was nil. Minor complications related to the procedure include hemorrhage, subcutaneous emphysema, etc. Conclusion: Thoracoscopy is relatively a safe and well-tolerated procedure with high diagnostic accuracy in undiagnosed pleural effusions, decreasing the need of formal diagnostic thoracotomy. Every chest physician must, therefore, consider this procedure to decrease the time lag in achieving the final diagnosis and to initiate the treatment as early as possible. [ABSTRACT FROM AUTHOR]

Background: Pleural effusions are common and devastating complication of advanced malignancies. Lung and breast cancers cause approximately 75% of all malignant pleural effusions. Pleural effusions associated with carcinoma breast (either malignant or paramalignant) pose diagnostic and therapeutic dilemmas for the treating chest physician. Materials and Methods: In a prospective study of analysis of unexplained pleural effusions, we performed medical thoracoscopy in 9 cases of carcinoma breast between April 2011 and September 2014. All the relevant clinical and paraclinical were collected and analyzed. Results: Sole pleural effusion was the most common radiological finding. This article reviews 9 cases of carcinoma breast patients, who had developed recurrent lymphocytic exudative pleural effusion, within a year of diagnosis. Thoracoscopy was diagnostic in all 9 cases with a histological diagnosis of metastatic carcinoma arising from the breast. Surprisingly malignant cells were negative in pleural fluid of all cases on three consecutive occasions. Conclusion: Carcinoma breast related pleural effusion is a common condition encountered in respiratory medicine and oncology. Thoracoscopic guided pleural biopsy is an effective and safe technique in patients with undiagnosed pleural effusion. It not only gives an accurate diagnosis but also gives a high degree of relationship between thoracoscopic appearance and primary disease or tumor classification. [ABSTRACT FROM AUTHOR]

Multiple myeloma is a malignant neoplasm of plasma cell origin that mainly affects bone marrow and skeletal system, producing large amount of light chain immunoglobulins. Pleural involvement in multiple myeloma is a rare complication which carries very poor prognosis. We report a case of multiple myeloma who presented with recurrent pleural effusion that was evaluated by means of thoracoscopy. [ABSTRACT FROM AUTHOR]
