Subcutaneous adipose tissue occupies the lower left portion of the image.  Fibrous connective tissue of the dermis occupies the remaining regions and includes a conspicuous artery, a small nerve, and a cluster of lymphocytes.  Several smaller blood vessels may also be seen.  Numerous capillaries in this area cannot be reliably recognized in this specimen.

The pink color in this image represents eosinophilic material, in this specimen mostly one of the following:

The pale background color represents unstained material, in this specimen one of the following:.

The very dark purple (nearly black) spots are cell nuclei.  At this resolution, they cannot be individually identified except by context.

Bright red spots at upper left are red blood cells.

Blood is routinely spilled when tissue samples are taken.  Usually, liquid blood is rinsed away during specimen preparation, so that even blood vessels themselves commonly appear empty.  In this case, some spilled blood appears at upper left, and a few other blood cells appear in several of the blood vessels.
