Necrotising arteritis in amoebic colitis.
Massive intestinal haemorrhage rarely occurs in amoebic colitis. We report a case of caecal amoebic ulcer in a 61 year old diabetic male who presented with massive lower intestinal haemorrhage requiring blood transfusion and emergency surgical intervention. Histologically, trophozoites of Entamoeba histolytica were seen invading the wall of the submucosal arteries, causing necrotising arteritis. Rupture of a necrosed artery probably caused massive haemorrhage.
