Table of Contents

Have you ever heard of nodular scabies? Probably not, because it is a pretty rare condition. But if you have ever had the unfortunate experience of getting it, you will never forget it! Nodular scabies is a skin condition that causes large, raised bumps to form on the skin. These bumps are filled with mites, which can be very itchy and frustrating to deal with. If you think you might have nodular scabies, make sure to see a doctor right away for treatment. There is no cure for nodular scabies, but there are treatments available that can help get rid of the mites and relieve some of the itchings.


What is nodular scabies?

Nodular scabies is a severe form of a skin condition known as scabies. It is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominins). The mites burrow into the skin, causing intense itching and irritation. They may also cause small, red bumps or nodules to form on the skin.


What are the symptoms of nodular scabies?

The most common symptom of nodular scabies is intense itching of the skin. This itching is often worse at night. The mites burrow into the skin, causing irritation and inflammation. This can lead to the development of small, red bumps or nodules on the skin.

Other symptoms of nodular scabies may include:

  • Skin rash
  • Sores from scratching
  • Thickened, crusty skin
  • Secondary bacterial infections

What are the causes?

Nodular scabies is caused by an infestation of the skin mite Sarcoptes scabiei. These mites are very small (about 0.4 mm long) and burrow into the skin to lay their eggs. The female mites can lay up to 25 eggs per day, and each mite can live for up to two months.

The most common way to get nodular scabies is by close contact with someone who has it. This includes sharing a bed or clothing with an infected person or having direct skin-to-skin contact. It can also be spread indirectly through objects that have come into contact with an infected person's skin, such as towels, sheets, or furniture.


How is it treated?

Nodular scabies is treated with a topical medication called permethrin. This medication is applied to the skin and left on for 8 to 14 hours before being washed off. It is usually applied once a week for two to four weeks. In some cases, oral ivermectin may be used in addition to permethrin.

If you have nodular scabies, it is important to treat all of your close contacts as well. This will help to prevent the spread of the infestation. All clothing, bedding, and towels should be washed in hot water and dried on high heat. Vacuuming carpets, furniture, and other surfaces can also help to remove mites and eggs.


What are the complications?

If left untreated, nodular scabies can lead to secondary bacterial infections of the skin. These infections can cause permanent scarring and may even lead to death in some cases. Nodular scabies can also be spread to other people, so it's important to get treatment as soon as possible.


Can it be prevented?

There is no sure way to prevent nodular scabies, but good hygiene and prompt treatment of any skin lesions can help reduce the risk of spreading the mites.

Nodular scabies is a form of human scabies that is characterized by large, raised bumps on the skin. The bumps are caused by an infestation of the skin mite Sarcoptes scabiei. This type of scabies is more common in people with weakened immune systems, such as those with HIV/AIDS or certain types of cancer. Treatment for nodular scabies typically involves the use of topical medications, such as permethrin or crotamiton cream. In some cases, oral medications may also be prescribed. Good hygiene and prompt treatment of any skin lesions can help reduce the risk of spreading the mites.
