FIGURE 53.14. Early histologic lymph node changes in cat scratch disease caused by Bartonella henselae. Note the vague rim of granulomatous inflammation surrounding a region of karyorrhexis and necrosis. Bacilli are most likely to be detected by staining techniques in early lesions such as this. H&E, original magnification, 4003.
