The authors report a case of a localized fibrous tumour of the pleura with huge proportions of 26 x 14 x 12 cm and 1.25 Kgr of weight, in a 56 year old female patient. The tumour occupied practically the inferior 2/3 of the right pulmonary field and had an unusual insertion in the diaphragmatic parietal pleura. It was non pediculous and had histological features of malignancy. The diagnosis of localized fibrous tumour of the pleura was achieved through observation of the sample obtained by fine needle aspiration. The immunohistochemical study subsequently done on the surgical specimen, confirmed the previous diagnosis. The evaluation of malignancy was based ou the following histological criteria: high cellularity, cellular pleomorphism, mitotic activity (more than four mitotic figures per 10 high power fields), hemorrhagic areas and necrosis.Downloads
