Crohn's disease
Perianal discomfort may also be prominent in Crohn's disease. Itchiness or pain around the anus may be suggestive of inflammation, fistulization or abscess around the anal area or anal fissure. Perianal skin tags are also common in Crohn's disease, and may appear with or without the presence of colorectal polyps. Fecal incontinence may accompany perianal Crohn's disease.
