Overview

[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].

OR

[Disease name] must be differentiated from [[differential dx1], [differential dx2], and [differential dx3].

Differentiating [Disease name] from other Diseases

[Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].

The following conditions may present in a similar manner as radiation proctitis, and should be excluded:

  • infectious colitis,
  • inflammatory bowel disease,
  • diversion colitis,
  • ischemic colitis,
  • chronic graft-versus-host disease,
  • diverticular colitis, and
  • medication-associated colitis

OR

[Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].

OR

As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].
