One of the most common salivary gland malignancies.

Major clinical features

- Wide age range (2nd-7th decades) - Parotid gland

- Major and minor salivary gland

( Major: 1-2 to10 %, Minor: 9% to 15-23% ) - Asymptomatic swelling


Histopathologic grades

1. Amount of cyst formation 2. Degree of cytologic atypia 3. Relative number of mucous,

epidermoid, and intermediate cell

Low grade:

Prominent cyst formation, minimal cellular

atypia, relatively high porportion of mucous cell.



Histopathologuc grade

Clinical stage: subtotal or total parotidectomy?

Prognosis depends.

- Low grade: 90-98%

- High grade: 30-54%
