[The pathoanatomical,diagnosis of progressive forms of pulmonary tuberculosis in relation to the new clinical...

This communication is a letter of information that gives for postmortem diagnosis a brief account of tuberculous inflammation and major types of pulmonary tuberculosis during their progression to death and an approximate outline of pathoanatomical diagnosis. Terminal tuberculosis is shown to be now complicated by miliary and caseous pneumonias. Caseous pneumonia may appear as an independent nosological entity and as a complication of acute progression, more frequently, of fibrocavernous tuberculosis. Caseous pneumonia as a tuberculosis type is an irreversible process that calls for emergency surgical treatment. It has been found that there are primarily impairments in lung connective tissue function, acute mesenchymopathy with high blood barrier permeability in caseous pneumonia. Terminal bronchiolar lesion is a later stage in the pathogenesis of caseous pneumonia.
