Thrombosed haemorrhoid. Close-up of the anus of a 63-year-old female patient with an external haemorrhoid (centre) that has become thrombosed. Haemorrhoids, or piles, are swollen veins protruding from the anus that can bleed and cause pain. Here a blood clot (thrombus) has formed in the vein, causing significant pain and swelling in the area of the anus.
