Anorectal pain, bleeding and lumps.
BACKGROUND
The patient presenting with anal pain, anal lump or rectal bleeding is a common occurrence in the general practice setting and the combination of symptoms usually gives an indication of the most likely diagnosis. However, careful examination including digital rectal examination is always required.


OBJECTIVE
This article discusses three common anorectal conditions: perianal haematoma, haemorrhoids and anal fissure, and briefly discusses the less common, but not to be missed conditions: anal carcinoma and low rectal carcinoma.


CONCLUSIONS
The majority of first degree haemorrhoids can be managed by conservative measures alone. More severe degree haemorrhoids require surgical intervention with sclerosant injection, rubber band ligation or surgical haemorrhoidectomy. Initial treatment for anal fissure is with a high fibre diet, faecal softeners, topical local anaesthetic gel and glycerol trinitrate ointment. Botulinim toxin can be injected to create a chemical sphincterotomy, allowing healing. Chronic fissures produce intense and constant pain in the anal region and in these cases surgical sphincterotomy is often necessary to cure the condition, but can result in faecal incontinence. Anal cancer has similar presentation to haemorrhoids and carcinoma of distal rectum can initially present with a haemorrhoid, so the possibility of anorectal cancer should be considered in any patient presenting with haemorrhoids, tenesmus and change in bowel habit.
