These clinical images show the plaques and patches invloving over half of the patient's body, specifically, the chest, back, and palm.

The peripheral blood (on the left) demonstrates several scattered atypical lymphoid cells with convoluted nuclear contours compatible with Sezary cells.

The peripheral blood (on the right) shows a normal lymphocyte to the bottom left and an abnormal Sezary cell to the top right.

The peripheral blood (on the left) shows two abnormal Sezary cells.

The peripheral blood (on the right) shows a Sezary cell on the top left along with a reactive monocyte at the bottom right.

The CD45 vs side scatter (plot on the left) demonstrates a large population of lymphocytes comprising 64% of all cells.

Further analysis using CD3 vs side scatter (plot on the right) on the right indicates that there are 61% CD3+ T-cells.

Further examination of the lymphocytes with CD4 and CD8 (plot on the left)demonstrates a large population of CD4 T-cells indicative of significantly skewed CD4:CD8 ratio >10:1. A minor population of normal T-cells is depicted in green, and a large abnormal population of CD4 T-cells is depicted in blue.

In the  CD4 vs side scatter (plot on the right), looking within the CD3+ T-cells indicates that the normal T-cells express moderate CD4 whereas the large population of abnormal T-cells express dim CD4 relative to these normal populations.

The plot on the left shows abnormal CD4+ T-cell population is negative for CD7 whereas the normal T cells (green population) as well as normal CD8 T cells (including NK cells) are CD7+/CD4- (smaller cluster in blue).

The plot on the right shows that the abnormal CD4+ T cell population is negative for CD26.
