Case 17, dermatopathic lymphadenopathy. A: FNC smear of dermatopathic lymphadenopathy: the smear shows a polymorphous dispersed cell population represented by small lymphocytes, scattered histiocytes and occasional eosinophils (Diff Quik stain 430X). B: Small lymphocytes with compact chromatin and histiocytes with vesicular nuclei (Papanicolaou stain 430X). C: FC showing balanced CD4/CD8 ratio, and CD2/3/7 co-expression assessing the polyclonality of the T-cell population. D: DHPLC chromatogram of the TCRγ amplification product showing multiple peaks, in a shape similar to a Gaussian curve, assessing the polyclonal status.
