What Are the Oral Lesions Associated With HIV?
HIV can weaken the immune system, making the mouth more prone to infections and sores. These oral changes are often among the earliest signs of HIV and may cause discomfort or pain. These oral problems can make eating, speaking, or swallowing uncomfortable. Below are some common mouth conditions linked to HIV:
-
Oral candidiasis (thrush, a fungal infection).
-
Periodontal lesions (serious gum diseases).
-
Herpes simplex virus infection (cold sores).
-
Herpes zoster (shingles).
-
Kaposi sarcoma (a type of cancer in the mouth).
-
Oral hairy leukoplakia (white patches on the tongue).
-
Aphthous ulcers (deep mouth sores).
-
Oral squamous cell carcinoma (mouth cancer).
-
Molluscum contagiosum (virus bumps).
-
Thrombocytopenic purpura (bleeding because of low platelets).
1. Oral Candidiasis:
This is the most common kind of fungal infection in the mouth linked to HIV. It happens when the fungus called Candida grows too much. This usually means the immune system is weak. Many times, seeing this in the mouth can tell doctors that the disease has reached a more serious stage.
There are four main ways it can look:
-
Pseudomembranous Candidiasis - This shows up as white or creamy patches inside the mouth. If you try to wipe them, they come off and leave red, sore skin underneath. These spots can spread over large areas, and they can even go into the throat area.
-
Erythematous Candidiasis - This one looks red and sore. It usually appears on the top of the tongue, the inside of the cheeks, or the roof of the mouth. When it is on the tongue, doctors sometimes call it central papillary atrophy (this means the tiny bumps on the tongue’s surface have worn down).
-
Hyperplastic Candidiasis - This type forms white plaques that stick firmly and cannot be wiped away. If doctors are unsure what it is, they might take a small piece of tissue (biopsy) to look at it more closely under a microscope.
-
Angular Cheilitis - This causes cracks and scaly skin at the corners of the mouth. It is caused by a mix of Candida and a common skin bacterium. This makes the mouth corners look red, sore, and split.
Diagnosis and Treatment - Many times, doctors can diagnose this infection by how it looks. They might take a smear or tissue sample to be sure. Special stains can show the fungus under a microscope. Treatment can be a medicine put directly in the mouth, like Nystatin or Clotrimazole, or a pill such as Fluconazole or Itraconazole. The pills usually keep the infection away longer, but they can interact with other medicines, and sometimes the fungus becomes harder to treat.
2. Periodontal Lesions:
-
This is a serious problem with the gums. It can destroy the support around teeth and is not easy to manage. Certain kinds of bacteria that do not need oxygen to live (anaerobic bacteria) can cause these lesions.
-
One type is called necrotizing ulcerative gingivitis, where the gum edge becomes very painful and bleeds. These sores can spread to the cheek lining and to the roof of the mouth. If it keeps going, the bone holding the teeth can be lost, and the teeth can become loose. People with this often have pain, fever, bleeding gums, and bad breath that will not go away.
Diagnosis and Treatment - The first sign may be gums that bleed even though there is not a lot of plaque (soft sticky film). Later, the gums pull away from the teeth, and the bone can become visible. Using antiseptic mouthwashes containing Chlorhexidine or Povidone-iodine can also help. It helps clean dead tissue. In severe cases, your doctor may prescribe antibiotics for the infection.
3. Herpes Simplex Virus (HSV) Infection:
-
It causes cold sores. HSV often starts as blisters, usually on the lips, that quickly burst and form shallow sores. If this infection is inside the mouth, usually on the gums, it is known as acute herpetic gingivostomatitis.
-
You may see many very small blisters that collapse into tiny sores with a red base and a yellowish covering. In people with HIV, these sores can stick around longer than usual and heal slowly.
Diagnosis and Treatment - Doctors cannot always be sure it is herpes just by looking. Your doctor may order tests that detect the growth of the virus’s DNA in a laboratory to confirm it. Your doctor may prescribe medicines such as Acyclovir to help with fast healing and reduce pain.
4. Herpes Zoster:
-
It causes shingles. Herpes Zoster can recur again and again in individuals with weak immune systems. It begins as a cluster of blisters, usually on the mouth area or one side of the face. In people with HIV, these blisters spread beyond this usual pattern, and they might leave scars after healing.
Diagnosis and Treatment - Tests that find the virus’s DNA are the best way to confirm this condition. Medicines such as Acyclovir, Famciclovir, or Valacyclovir can help the body fight the infection.
5. Kaposi’s Sarcoma:
-
This is a kind of cancer that often occurs in the mouth, more commonly on the hard palate (the roof of the mouth) and gums. These spots are usually red or purple and can lie flat, stick up, or form bumps. When they become large, they might bleed and make it hard to swallow food.
Diagnosis and Treatment - To be sure it is this cancer, doctors take a small piece of the lesion (biopsy) and look at it carefully. Treatments include injecting medicine right into the lesion, cutting it out, or giving strong medicines (chemotherapy) if the disease has spread. Treating HIV itself often makes these lesions get better.
6. Oral Hairy Leukoplakia:
-
This looks like white, wrinkled patches on the sides of the tongue. It is caused by the Epstein-Barr virus, which can take hold when the immune system is weak. These patches cannot be wiped off. They are a strong sign that the HIV disease is advancing.
Diagnosis and Treatment - Doctors use special laboratory tests to confirm that the Epstein-Barr virus is present. This condition does not turn into cancer. Treatment may include antiviral medicines, and often getting better control of HIV helps the patches go away.
7. Aphthous Ulcers:
-
These are round, painful mouth sores that come and go. They are usually found on the inner cheeks, lips, or tongue. In people with HIV, they can be much larger and deeper than usual and take longer to heal.
Diagnosis and Treatment - Doctors may take a sample from the sore or perform blood tests to determine what is causing it. These ulcers may be treated with medicine that reduces swelling. Rinsing the mouth with helpful rinses can ease pain and help with healing.
8. Oral Squamous Cell Carcinoma:
-
This is a type of mouth cancer. People with HIV can get this cancer at a younger age than others. This may be because the immune system cannot recognize dangerous cells well, or because other infections, like HPV (human papillomavirus), happen more easily.
Diagnosis and Treatment - A biopsy is the best way to know for sure. Treatment usually includes surgery, chemotherapy, or radiation, depending on how far the cancer has spread.
9. Molluscum Contagiosum:
-
This is a viral skin infection that can appear in the mouth. It looks like shiny, dome-shaped bumps with a tiny pit in the centre. When a person has many of these bumps, they can be uncomfortable or bothersome.
Diagnosis and Treatment - Doctors usually check the appearance of the bumps and diagnose them based on their appearance. Sometimes, they can scrape it a bit and check it under a microscope. Its treatments include freezing it or taking antiviral medicines. In cases where medications do not help, doctors might advise removing them with tools or a laser.
10. Thrombocytopenic Purpura:
-
It occurs when the body has very few platelets (cells that help stop bleeding). Platelets may decrease because of HIV, certain medicines, poor nutrition, or infection. This can cause tiny red or purple spots in the mouth and gums that bleed easily, especially after chewing food.
Diagnosis and Treatment - Blood tests that show low platelets help doctors know how HIV is affecting the body. Treatment may include platelet transfusions or medicines to support the immune system.
Conclusion
There are many mouth problems linked to HIV. The ones doctors see most often are gum disease (periodontitis), oral candidiasis, and oral hairy leukoplakia.
With the right medicines for infections and close medical care, these mouth problems can be managed. It is very important to talk to an HIV specialist doctor early so a proper plan can be made, and discomfort can be reduced.
Key Takeaways
-
HIV weakens the body’s immune defenses, which can lead to several mouth problems that often show how far the disease has progressed.
-
Issues like oral candidiasis, the most common fungal infection in people with HIV, and oral hairy leukoplakia are clear signs that the immune system is under serious strain.
-
Spotting these oral changes early and treating them properly, along with keeping HIV under control, can help prevent further problems and improve overall health.
