Classification
- Pleomorphic adenoma can be classified on the basis of the histological appearance i.e, epithelial and stromal changes into the following subgroups.[1]
- Subgroup 1 (30,5%) is the classical pleomorphic adenoma with a stroma content of 30-50%
- subgroup 2 (55%) has a stroma content of 80%
- subgroup 3 (9%) has a poor stroma content of 20-30% or less and an epithelial differentiation similar to subgroup 1
- subgroup 4 has also a poor stroma content (6%) with a relatively monomorphic epithelial structure.
