2 FIGURE 1 A, Histology (hematoxylin-eosin staining) of localized pleural mesothelioma of mixed (sarcomatoid and epithelial) type with initial bone and pulmonary infiltration; the spectrum of microscopic findings shows several nodules partially necrotic onto desmoplastic stroma; B, sarcomatoid component.

3 FIGURE 2 Thoracic computerized tomography (CT) shows a pleural mass with smooth margins and without ribs infiltration in the superior lobe of the right lung.

4 FIGURE 3 Thoracic computerized tomography (CT) shows a lobulated pleural mass with smooth margins and without ribs infiltration in the apex of the pleural cavity.

5 FIGURE 4 A, Histology (hematoxylin-eosin staining) of localized pleural mesothelioma of sarcomatoid type, lympho-histiocitoid variant. The neoplastic lesion shows a solid structure, inflammatory infiltration and focal necrosis; B, intermediate-large fusiform cells with abundant cytoplasm and severe cytologic atypia with frequent atypical mitoses.
