Hemorrhoids, which are venous dilatations of the anus or rectum.

The pinworms are small grubs and a few millimeters long, parasites of the terminal part of the human intestine. They are highlighted by scotch-test. This technique developed by Graham collects pinworm eggs that were laid on the margin of the anus. It uses a transparent adhesive tape, which will be examined under a microscope, after sticking the tape on a slide.

The sawgrass is a small swelling (size) of the anal margin wrapped in a skin. Wrinkled and soft, the sawgrass is painless and is the result of a hemorrhoid which turned into having lost his usual strength.

Anal fissures, requiring special treatment by incision and drainage.

Abscesses of the anus. Anorectal abscess, which is a relatively common condition, is a collection of pus located within a cavity formed around the rectum and from a fold of the wall which has penetrated between the muscles of the anatomical region that normally allow closing of the anus (sphincter). The pus is a pathological exudate (from illness), a liquid, disorder, usually yellowish in color, containing leukocytes (white blood cells) altered cell debris from the body, cell necrosis (destruction) or not, or not containing or germs (microbes) exudate liquid from the body oozing at an inflamed surface.

The causes of anorectal abscesses are relatively numerous. It can be an inflammation of the bowel such as diverticulitis, ulcerative colitis or Crohn's disease. Apart from these gastrointestinal diseases, surgery may lead to the development of anorectal abscess.

When the abscess is superficial palpation can highlight a lump (swelling) in color red and painful.

Deep abscesses can sometimes be a source of infection throughout the body. This is reflected by the appearance of hyperthermia (fever) and fatigue (asthenia) more or less important. In case of deep abscess, rectal examination, consisting of a finger to penetrate inside the anus), reveals the presence of a ball complained the patient and is very painful.

It is sometimes necessary to carry out a rectoscopy, that is to say, to the visualization of the interior of the rectum (through the anus), using a rigid tube and a light.

The evolution of anorectal abscess may be towards the emergence of a complication related to the spontaneous formation of a communication of the abscess with skin. This communication can also be done with another organ such as the vagina or bladder through a conduit through which flows the pus. This duct is called a fistula.

The treatment of anorectal abscess requires a small surgery. It aims to open the abscess and drain pus through an incision followed by drainage.

The exanie (a term derived from the Latin ex: out and anus, English exania) means prolapse of the rectum.

The meliena (Greek Melaina: black), also called melena means the evacuation anus; black blood is mixed with feces, often adopting tarry.

The anal cancer is relatively rare, which presents itself as a lesion that bleeds and heals poorly. It is essentially cancer tissue lining (squamous), rarely adenocarcinoma (glandular cancer). This cancer is usually accompanied by glands in the groin (inguinal), and requires radiotherapy sometimes associated with surgery to remove the tumor when it reaches a large volume. The results are generally good, especially in localized forms.

The hedrocele (Greek hedra, anus and Kele: hernia), English hedrocele is the herniated bowel loops exiting through the anus into the rectum is pushing prolab adjective prolapsed is derived from the Latin labi that means falling.

Plate mucosa is an injury due to secondary syphilis, localized mucosal and skin covering the parts near the orifice such as the anus, vulva where the mouth. These superficial lesions characterized by mucosal erosion chorion, that is to say, the deep layer of the mucosa, which is the set of cells covering the inside of hollow organs in contact with air. Sometimes the lining plate has a projection very large. In other patients there is an abrasion buds giving a smooth plates known as swaths of Fournier. Lesions are colored reddish opal, that is to say, having milky hue, iridescent opaline as the porcelain. It is contagious lesions, which are sometime  covered with exudate (oozing fluid) close to what can be seen in diphtheria?

The aproctie (from Greek: Private and proktos: anus) in English aproctia refers to congenital absence of an anus.

The ectro-urie (Greek ektroo: I abort and oura: tail), English ectrouria means the monstrosity characterized by the lack of development of the caudal end (opposite the head) of the embryo. These malformations affect the genital and urinary tract, rectum, anus and the sacrum. These elements are either rudimentary or completely absent. Malformations also involve both lower limbs, which is referred to as ectromelia. The two members are sometimes welded together, then it is a sirenomelia.
