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].

Overview

Radiation proctitis must be differentiated from infectious colitis,inflammatory bowel disease,ischemic colitis,medication-associated colitis,chemical colitis and allergic colitis

Differentiating Radiation proctitis from other Diseases

The following conditions may present in a similar manner as radiation proctitis, and should be excluded:[1]

The table below lists the differential diagnosis of common causes of colitis:
