[Pleural puncture biopsy--a diagnostic method in serofibrinous tuberculous pleurisy in children].

The biopsy of the parietal biopsy with the help of a needle has become an essential method of diagnosis in the adult patients with a pleural malady of an unknown etiology and may become a complementary paraclinical method in children. A sure diagnosis in the tubercular serofibrinous pleurisy with children is made by rendering evident the Koch bacillus on the direct test or in culture and by rendering evident the tubercular lesions on fragments of pleural biopsy puncture. The study is supported on the results obtained at the pleural biopsy puncture performed on a number of 6 children. In four cases out of six the histological test of the pleural fragment has rendered evident the presence of tubercular lymphoepithelioid nodulus with central necrosis, thus carrying the argument of certitude. The pleural biopsy puncture allows an early and sure diagnosis in over two-thirds of the pleurisies of a tubercular etiology.
