Wehave many examples of this typeof metastasis in our plate files. The differential diagnosis ofthe miliary variety of metastasisis much more difficult than theidentification of the nodular , the miliary type isfar less frequent than the nodu- lar. Simulants from which itshould be distinguished are themiliary type of tuberculosis andpneunionoconiosis. In acute miliary tuberculosisthe lesions are more numerous,smaller, and less dense than inmiliary metastasis; if the miliarytubercles are associated withchronic tubercu
