Specimen Submitted:

            Tissue biopsy fixed in formalin

Test Requested:

            Routine histopathology, surgical margins

            Cytology

Results:

            This section is a circumscribed 2.3 cm x 1.8 cm subcuticular mass with skin taken from the region of the dorsal back.

            Histopathologic examinations reveal a mass composed of cells arranged

            in sheets subdivided by a few thin fibrous trabeculae.  Cells are round with

            abundant, high vacuolated cytoplasm and flattened nuclei without evidence

            of atypia.
