Aim: The authors made a morphological evaluation of pleural tissue fragments from patients hospitalized in Thoracic Surgery Department of the Emergency County Hospital of Craiova, Romania, over a period of 26 years, diagnosed with tuberculous lesions in the Pathology Department of the same Hospital. Patients, Materials and Methods: The studied material consisted of pleural tissue samples taken by biopsy or surgical excision from 39 cases coming out of 841 patients investigated in the above-mentioned period of time and diagnosed from histological point of view with tuberculosis (TB). Granuloma cell population was assessed using immunohistochemical method. For diagnostic confirmation, Ziehl-Neelsen staining has been used as a rule but, in some cases, immunohistochemistry was also used. Results: TB lesions predominated in men usually around or over 50 years old. The diagnostic was suspected in almost half of the cases. Right cavity was more affected and the extended fibrosis was present in a significant number of cases. The inflammatory conflict was of reactive type, with giant Langhans cells granulomas and acidophilic necrosis but sometimes with superinfection or significant fibrous sequelae. Conclusions: Pleural effusions of TB origin are a reality more and more present due to the recrudescence of pulmonary TB in the last decades. Their presence should be suspected if faced to a unilateral pleural effusion with free-flowing fluid occurred almost often to a man of any age from youth to elderly.
