title: [Pulmonary granuloma, pseudolymphoma and lymphoma].
abstract: We are presenting 10 patients with tumors of the lungs - granulomas or lymphomas - among more than one thousand patients suffering from lung cancer. Apart from the granulomas with its obvious inflammation characteristics, it seems that the distinction between pseudolymphomas and malignant lymphomas is possible through histological examinations but contrary to their clinical evolution. Two patients with s-called pseudolymphomas have shown recurrent bilateral recidivism. As shown in all medical literature, the good prognosis of pulmonary lymphomas makes the distinction between pseudolymphomas and lymphomas futile. Nonetheless, it should be noted that clinical symptoms in markedly malignant cases can appear after several symptom free years. None of our patient has died from their pulmonary condition. Only thoracic exploration and surgical ablation of the lesion permit a correct diagnosis and a satisfactory therapeutic approach. The surgical ablation of the lesion must be economical, because of frequent recurrence, sometimes bilateral. Both patients with so-called pseudolymphomas and the one with malignant lymphoma showed bilateral recurrences successfully treated by radiotherapy, with 10--15 years survival rate.
