Searching for pictures of AIDS lesions is honestly a heavy experience. You’re likely here because you saw something on your skin—a weird bump, a purple spot, or a rash that won't quit—and your brain immediately went to the worst-case scenario. Or maybe you're a student or a caregiver trying to understand the visual progression of HIV. Either way, the internet is full of terrifying, grainy photos from the 1980s that don't reflect the reality of modern medicine. It's scary.
We need to be clear: the term "AIDS lesions" is actually a bit of a catch-all. It usually refers to skin conditions that happen when the immune system is severely compromised. Most people living with HIV today, thanks to Antiretroviral Therapy (ART), never actually develop these. But when someone’s CD4 count drops significantly, the skin becomes a primary canvas for opportunistic infections.
What Kaposi Sarcoma Actually Looks Like
When people search for pictures of AIDS lesions, they are almost always looking for Kaposi Sarcoma (KS). It became the "face" of the epidemic in the early years. Unlike a typical rash, KS is a cancer of the blood vessels caused by Human Herpesvirus 8 (HHV-8). It doesn't look like a pimple. It doesn't look like a hive.
In the beginning, KS might just look like a small, flat bruise. You’d think you just bumped your shin on the coffee table. But it doesn't fade. It stays. Then it might turn into a firm papule. The color is the giveaway—it's usually deep purple, red, or brown. On darker skin tones, these lesions can look black or dark grey, making them even harder to spot early on. They can show up anywhere: the soles of the feet, the face, or even inside the mouth on the gums or palate.
Dr. Marcus Conant, one of the first physicians to recognize the outbreak in San Francisco, often noted how these lesions were the first physical sign of a collapsing immune system for many young men. They aren't usually itchy or painful at first, which is why people ignore them. But as they grow, they can merge into larger plaques. If they develop in the lungs or digestive tract, it’s a much more serious situation than just a skin spot.

The Viral and Fungal Mimics
Not every "AIDS lesion" is Kaposi Sarcoma. Far from it. When your immune system isn't guarding the door, mundane viruses throw a party.
Take Molluscum Contagiosum. In a healthy person, these are tiny, pearly bumps that eventually go away. In someone with advanced HIV, they can explode across the face and neck. They look like small, flesh-colored domes with a tiny dimple in the middle. If you see pictures of AIDS lesions that look like hundreds of tiny white pearls, that’s likely what you’re seeing. It’s a viral infection that the body just can’t suppress anymore.
Then there’s Eosinophilic Pustular Folliculitis. That’s a mouthful. Basically, it’s an intensely itchy rash that looks like hives or acne, usually on the upper body and face. It’s frustrating because it’s so incredibly itchy that patients often cause secondary infections by scratching. It’s not "cancerous" like KS, but it’s a sign that the immune system is in total disarray.
Why "Old" Pictures Are Misleading
If you go to a stock photo site or an old medical textbook and look at pictures of AIDS lesions, you are seeing the extreme end of the spectrum. You're seeing the pre-1996 era. Back then, there was no way to stop the virus from replicating, so the skin conditions became "giant" or "disseminated."

Today, skin issues in people living with HIV often look just like skin issues in anyone else. They just might be a bit more stubborn. Psoriasis can be more severe. Seborrheic dermatitis—that flaky, red skin around the nose and eyebrows—is super common. Honestly, many people see a bit of dandruff and a red nose and panic, thinking it's an "AIDS lesion." Most of the time, it’s just a common skin condition exacerbated by a bit of immune stress.
Critical Visual Differences
- Bruises vs. KS: A bruise changes color (blue to green to yellow) and fades in two weeks. A Kaposi Sarcoma lesion stays the same color and persists.
- Acne vs. Molluscum: Acne usually has a whitehead or blackhead and comes and goes. Molluscum bumps are firm, waxy, and have that central "indent."
- Shingles: This is a big one. Shingles (Herpes Zoster) follows a nerve path on one side of the body. It’s painful and blistering. In younger people, a severe case of shingles is often what prompts a doctor to suggest an HIV test.
The Role of Oral Candidiasis (Thrush)
We can’t talk about visual signs without mentioning the mouth. Oral thrush is a fungal infection caused by Candida. It looks like thick, white "cottage cheese" patches on the tongue or the insides of the cheeks. If you try to scrape it off, it usually leaves a red, raw, or even bleeding spot.
While anyone can get thrush (especially if you're on heavy antibiotics or use an inhaler), persistent thrush is a hallmark sign that the CD4 count is struggling. It’s often one of the first things a dentist might notice. It’s not a "lesion" in the sense of a wound, but it is a visual indicator that shows up in almost every clinical database of HIV-related symptoms.
Does a Skin Spot Mean You Have AIDS?
Short answer: No.

Longer answer: You cannot diagnose HIV or AIDS by looking at a photo. Skin is tricky. Even top-tier dermatologists sometimes need a biopsy to tell the difference between a weird fungal infection and a malignancy. If you are looking at pictures of AIDS lesions because you found something on your body, the only "correct" next step is a blood test.
The CDC and organizations like the San Francisco AIDS Foundation emphasize that "AIDS" is a clinical diagnosis based on CD4 cell counts (less than 200 cells/mm³) or the presence of specific opportunistic infections. Many people live for decades with HIV and never reach the "AIDS" stage. If you have a lesion and you do test positive, the treatment is actually the same: get on ART. When the viral load becomes undetectable and the CD4 count rises, many of these "lesions"—including Kaposi Sarcoma—actually shrink or disappear entirely without specific skin treatment. The body starts fighting back again.
Dealing with the Anxiety of the Search
"Cyberchondria" is real. You spend three hours looking at Google Images and suddenly you're convinced your mosquito bite is a terminal diagnosis. It’s an exhausting cycle.
Understand that HIV today is a manageable chronic condition. The "lesions" you see in historical photos are now largely preventable and treatable. If you’re worried, look for clinics that offer "fourth-generation" testing. These tests look for both antibodies and the p24 antigen, which can detect the virus much sooner than older tests—often within weeks of exposure.
Practical Next Steps
Stop scrolling through images. Skin conditions are notoriously hard to self-diagnose because so many things look alike under a smartphone flashlight.
- Get a Test: This is the only way to know. Use CDC’s GetTested to find a free or low-cost site near you. It’s fast, and in many places, it's anonymous.
- See a Dermatologist: If the spot is new, changing, or won't heal, a skin specialist needs to see it. Don't lead with "I think I have AIDS." Just say, "I have this lesion that isn't healing." Let them do the diagnostic work.
- Check Your History: Have you been at risk? If you haven't had unprotected sex or shared needles, the likelihood of a random spot being an AIDS lesion is statistically near zero.
- Monitor the Spot: Does it blanch (turn white) when you press it? Does it hurt? Is it spreading? Write these things down so you can tell a doctor.
- Focus on Overall Health: Skin is often a mirror of what’s happening inside. Stress, lack of sleep, and poor diet can cause "flares" of many conditions that look scary but are ultimately benign.
The images you see online are snapshots of a specific moment in medical history. They aren't a crystal ball for your future. Modern medicine has turned what was once a visual "death sentence" into something that is often invisible to the naked eye.
