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

  • Colon polyps may be classified into two groups:
    • Neoplastic
    • Non-neoplastic
      • Inflammatory polyps
        • Inflammatory pseudopolyps
        • Prolapse type inflammatory polyps
        • Myoglandular polyps
      • Hamartomatous polyps
        • Juvenile polyps
        • Peutz-Jeghers polyps
        • Cronkhite-Canada syndrome
        • Phosphatase and tensin homolog (PTEN) hamartoma tumor syndrome
      • Serrated polyps
        • Hyperplastic polyps
        • Traditional serrated adenomas
        • Sessile serrated polyps
        • Serrated polyposis syndrome
      • Adenomatous polyps

Adenomatous polyps may be classified into several subtypes based on:

  • Endoscopic features
  • Histologic features
  • degree of dysplasia

Adenomas may be classified according to endoscopic features into four groups:

  • Sessile
  • Pedunculated
  • Flat
  • Depressed

Adenomas may be classified according to histologic features into three groups:

  • Tubular
  • Villous
  • Tubulovillous

Adenomas may be classified according to degree of dysplasia into two groups:

  • Low-grade dysplasia
  • High-grade dysplasia
