Pathology Report

MICROSCOPIC DESCRIPTION:
Sections show tumor, composed of variably cellular areas admixed with areas within which there is a myxoid connective tissue stroma, within which scant myoepithelial cells are seen. Within the glandular areas, glands are seen, some with tubular arrays of uniform cells with a fine nuclear chromatin
pattern and ovoid nucleus with a small amount of surrounding cell cytoplasm.
The tumor is present throughout the tissues and extends to the resection margins. No vascular or perineural invasion is seen.

DIAGNOSIS/COMMENT:
