Answer

Routine histologic examination of hemorrhoidal tissue is usually unrewarding, especially if it is grossly examined by an experienced anorectal surgeon. Any suspicious tissue must be sent for microscopic evaluation. External hemorrhoids are classified by the underlying pathology and symptoms, which include thrombosed veins, bleeding from eroded blood clots, and skin tags causing hygiene problems.
