Localized mesothelioma of the pleura: benign and malignant variants

摘要: Mesothelioma, even of the pleura alone, is a ubiquitous pathological designation. The diffuse variety associated with an ominous prognosis. localized mesothelioma generally has been assumed to be benign. A review tumors from 60 patients pleural seems justify separation into benign (52 patients) and malignant (eight variants. Histologic criteria are used primarily make this division. No single clinical feature allowed preoperative predictability concerning benignity or malignancy, although extrathoracic osteoarthropathy was seen only lesions (20 percent), usually those greater than 7 cm. Follow-up periods as long 24 years revealed recurrent tumor in two 58 survival curve identical that general population. All had recurrence metastasis, all but one were dead within 2 initial operation. One patient died complications after 9 years. More aggressive local resection indicated for variant.
