Spermatocytic Tumor : Touch Prep

Microscopically, the spermatocytic tumor shows a polymorphous population consisting of three major cell types: numerous small, lymphocyte-like cells with hyperchromatic, smudged nuclei; moderate numbers of intermediate-sized cells with round nuclei containing granular chromatin; and scant numbers of large cells that may be multinucleated.

The intermediate-sized and large cells have one or more punctate nucleoli. In addition, some cells have characteristic filamentous chromatin similar to that seen in normal meiotic-phase spermatocytes (spireme chromatin).

This air-dried touch-prep (Diff-Quick stained) from the freshy cut tumor surface shows all three cell populations.
