Overview

There is no established system for the classification of Angiodysplasia.

OR

Angiodysplasia may be classified according to endoscopic appearance into 4 subtypes: Type 1, Type 2, Type 3, and Type 4.

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].

Type3: AV malformations : Pulsatile red protrusion, without surrounding venous dilation

Type 4: Unclassifiable : Lesions that cannot be classified in one of the above categories.
