Example of the FC analysis performed in an FNA sample taken from a salivary gland. A T-cell lymphoma was detected by evidencing the presence of a small anomalous T-cell subset (13% of all lymphocytes, shown in red), which brightly expressed CD5, and resulted in CD4+ and CD7- at a low intensity. This population was homogeneously positive for CD45RO, displayed a heterogeneous expression of CD2 and expansion of the Vβ20 region of the T-cell receptor (TCR).
