Images of the different tissue manifestation of TB were taken using the 10x objective from at least 5 regions of multiple cases. The total number of cells was determined using the hematoxylin stain. The data are presented as the percentage of cells positive for a given marker, ±SD.
a P < .05, comparison to granuloma.
b P < .05, comparison to lipid pneumonia.
