I am sure that you will agree that salivary gland histologic classification can be very difficult.

From the above discussion, some favor adenoid cystic carcinoma, others favor benign tumors.

Please consider the following: tumor edge, types of cells, true tubules or not, do we have chondromyxoid stroma, what about the cellular arrangment, pleomorphism, peripheral cellular palisading, cysts or mucus cells?

I did try to the complete history intially.

We asked the surgeon where exactly the tissue was from.

The answer was "perhaps submandibular gland".
