Anal folds, perianal folds, outpost folds, anal lobules, anal polyps, anal skin peaks, skin carbuncles, or perianal fibromas.

Marisques are harmless folds of skin at the anus entrance that usually do not cause any symptoms and have no pathological value. However, they can cause unpleasant discomfort in case of infections and inflammations. Most experience itching or a burning sensation in the anal area. Mariscuses usually do not require treatment. At most, they are cosmetically disturbing or make anal hygiene more difficult. Only if they cause problems, surgery is advisable. The wound usually heals without consequences.

What are mariscs?

Mariscuses are benign, harmless skin flaps or nodules that form on the outer edge of the anal outlet around the anal entrance. Marisks are covered by the anal skin. They are skin-colored, do not hurt, may be isolated or multiple, and feel soft or coarse. Marisks can vary in size – from a few millimeters to a few centimeters. The name Mariske comes from the French word “le marisque”. There are countless other terms for mariscs that are in common synonymous use, for example: Skin bulges, anal folds, perianal folds, outpost folds, skin flaps, anal lobules, anal polyps, anal skin peaks, skin carbuncles or perianal fibromas.

Mariscuses can form primarily. No organic cause can be found for this. In addition, there are secondary mariscs, which often develop as a result of another disease, for example, perianal vein thrombosis.

Mariscus – frequency and age

Mariscuses form in many people. For example, about 75 percent of women and 70 of men develop skin folds around the anal opening during their lifetime. At a younger age, single mariscs usually develop, later it can become several folds of skin. They do not regress. Mariscuses occur in people of all ages, even in babies. In women, they occur in younger years of life (second decade of life), in men somewhat later (fourth decade of life). The risk of marisk increases with age.

Marisk: Causes and risk factors

Doctors distinguish two forms of marisk – depending on the cause. In primary mariscae, no organic cause can be identified and the reasons for their development remain obscure. “Idiopathic” is what doctors call it. They are the most common.

In addition, there are secondary mariscs, which are associated with a disease. The following causes of secondary marisk may be considered:

  • Chronic anal fissure associated with inflammation – outpost folds form.
  • Healed perianal vein thrombosis – mariscs sometimes remain.
  • Surgical procedures, for example the operation of anal fistulas or hemorrhoids
  • Perianal infections or stool particles that cause inflammation – mariscs could develop as the anal mucosa attempts to repair itself.
  • Crohn’s disease, a chronic inflammatory bowel disease (IBD).

Scientists suspect that some risk factors may promote mariscae – but the connections have not been proven. The following factors may be involved:

  • Frequent, thin stools that irritate the sensitive anal mucosa and cause inflammation.
  • Pregnancies: Strikingly often mariscae form during pregnancy and after delivery.
  • Hemorrhoids
  • Overstretching of the anal mucosa
  • Excessive anal hygiene
  • Underwear too tight

Symptoms: Marisci usually do not cause any symptoms

Marisci very rarely cause symptoms. At most, they can be a hygienic or cosmetic problem. The skin folds are difficult to clean and fecal debris can accumulate there. Some therefore overdo it with anal hygiene and irritate the skin mechanically. The same effect has too tight underwear. In addition, the warm, moist environment in the skin folds provides an ideal breeding ground for bacteria or fungi. They can settle there, multiply and cause inflammation.

Then the following symptoms can occur with mariscs:

  • Itching
  • Burning
  • Weeping
  • Skin redness
  • Spotting on toilet paper or in underwear

If the symptoms do not subside with self-treatment, you should consult your doctor. The right person to contact for mariscus is first your family doctor, who may refer you to a specialist in proctology.

Marisk: diagnosis with us

Experienced physicians often recognize mariscs at first glance. Typical are the skin folds grouped around the anal opening. Unlike hemorrhoids, marisci do not swell when you squeeze. Diagnosis can usually be made by visual inspection, palpation with a finger, and possibly examination with a proctoscope (reflection of the anus).

It is important in the diagnosis to rule out other diseases. Examples include hemorrhoids, anal genital warts, anal fibroids, or anal cancer (anal carcinoma).

Mariscus: prevention, early detection, prognosis

In many cases, the causes of mariscae are unknown. Thus, you can not really prevent the development of the skin wrinkles either. Be sure to maintain good anal hygiene, but don’t overdo it with cleaning. This is because all the wiping and scrubbing in the anal region can strain the sensitive anal skin and trigger inflammation. It is also better not to wear underwear that is too tight – it can also mechanically irritate the skin.

In addition, have conditions such as perianal vein thrombosis or chronic anal fissure adequately treated. As a result, mariscuses may develop. In addition, there are some preventive measures for both diseases. Some you can even do yourself and avoid inflammation in the anal area.

Specific measures for the early detection of mariscs are not known. This would also make little sense, because the skin folds are harmless and usually do not cause any symptoms. In general, if the mariscs cause problems, for example, inflammation, always see your doctor.

Marisk progression and prognosis

The course and prognosis for mariscs are good. The skin folds do not tend to grow further. However, they also do not regress on their own. The skin folds can cause repeated inflammation, which is unpleasant. Also, the actually soft mariscs can harden due to the inflammation and form coarse knots.

Mariscus: treatment depending on symptoms

In most cases, mariscae do not cause symptoms and treatment is not necessary. The skin folds are harmless and we usually do not need to remove them. However, mariscuses can become inflamed when irritating factors affect the sensitive anal skin.
