Overview
There is no established system for the classification of [disease name].
OR
[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].
OR
[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].
OR
Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.
OR
If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].
OR
The staging of [malignancy name] is based on the [staging system].
OR
There is no established system for the staging of [malignancy name].
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.
