[Pathomorphosis of infiltrative pulmonary tuberculosis: clinical aspects].

Based on the data available in the literature and their own findings, the authors have established that the pathomorphism of infiltrative pulmonary tuberculosis in the preantibiotic age was characterized by negative features, then underwent phases of positive changes and relative stabilization, thereafter it again acquired obviously marked negative peculiarities. At present, the clinical features of new cases of infiltrative pulmonary tuberculosis in Perm residents are the predominance of acute onset (67.3%), disseminated (55.8%) and destructive (91.6%) pattern of specific lesion accompanied by bacterial isolation (84.6%).
