posted: 25-Feb-2021          closing: 25-Aug-2021

The lesion (Figures 1–4) was observed in the spleen as an incidental finding in a male A/J mouse which was sacrificed at the end of a long term study. Cells of similar appearance were found isolated or in very small clusters also in the liver (Fig. 5).
