Vascular skin lesions can be puzzling when they appear out of the blue or start multiplying on your body. Two conditions that often confuse people are cherry angiomas and petechiae. If you’ve wondered about cherry angioma vs petechiae, you’re in the right place. Both are related to blood vessels, but they have distinctly different causes, appearances, and potential health implications.
Whether you’re a beauty enthusiast striving for clear, glowing skin or someone worried about a small red spot that popped up overnight, knowing the difference is vital. In places like Fort Lauderdale, where sunshine and beach outings are a way of life, people tend to notice skin changes quickly. And sometimes, what looks like a harmless spot can be a sign of something that needs medical attention. With that in mind, let’s talk about both cherry angiomas and petechiae—what they are, how to recognize them, and when to seek professional guidance from the best dermatology specialists in Fort Lauderdale.
Cherry Angiomas
Definition and Characteristics
Cherry angiomas are small, benign skin growths composed of tiny capillaries that clump together, creating bright red or purplish papules. You might hear them referred to as “senile angiomas,” but don’t let that term fool you—these can appear in early adulthood, though they’re more common as you age. Typically, they pose no health risk. However, they can occasionally catch on clothing or bleed, especially if they protrude slightly from the skin’s surface.
These growths are:
- Benign vascular lesions formed by capillary proliferation
- Often round or oval
- Known for their striking red hue, hence the name “cherry”
While they’re mostly harmless, it’s always a relief to know exactly what’s behind any mysterious new spot on your body.
Clinical Features
Cherry angiomas usually stand out because of their vivid coloring and dome-like shape. They are:
- Bright red, smooth papules that can appear slightly elevated
- Typically 1–5 mm in diameter, though some can be larger
- Commonly found on the torso, arms, and shoulders, but can show up almost anywhere
You might notice just one or two, or you could have many scattered across your skin. In most cases, they’re asymptomatic, meaning they don’t hurt or itch.
Dermatoscopy Findings
Dermatoscopy, also called dermoscopy, is a technique for examining skin lesions with magnification and special lighting. Under dermatoscopy, cherry angiomas often exhibit:
- Red, blue, or purple lacunae (small, well-defined spaces within the lesion)
- Clearly well-demarcated borders indicate the edges are sharp and easy to differentiate from the surrounding skin
These findings help confirm the diagnosis if there’s any doubt about what a lesion might be.
Eruptive Cherry Angiomas
Most cherry angiomas develop slowly over time. However, in some individuals, there can be a sudden influx of multiple new lesions. When this happens, doctors call it “eruptive cherry angiomas.” Various factors may be involved:
- Certain medications or chemical exposures
- Underlying systemic conditions that may increase vascular proliferation
Even though eruptive angiomas can look alarming, they’re still typically benign. Still, if you ever see a rapid change in your skin, it’s wise to check with a professional. The best dermatology specialists in Fort Lauderdale often recommend monitoring for any unusual changes or increases in number.
Treatment Options
In general, cherry angiomas don’t require removal unless they’re causing discomfort, frequent bleeding, or cosmetic concerns. If you do decide to treat them, there are several modern options:
- Laser treatment using pulsed dye or Nd:YAG lasers
- Electrocauterization, where electric current removes or destroys the lesion
- Cryotherapy, which uses extreme cold to freeze off the angioma
These procedures are relatively quick and can improve skin appearance without leaving prominent scars.

Petechiae
Definition and Characteristics
Petechiae are tiny, pinpoint red or purple spots (each about 3 mm or less in diameter) that form due to minor hemorrhages under the skin. Because they originate from small amounts of bleeding, petechiae don’t blanch (turn white) when pressed. Instead, they keep their color because the blood has already escaped from the vessels.
Key highlights:
- Small (≤3 mm), non-blanching macules
- Caused by tiny ruptures in capillaries under the skin
- Often appear in clusters, giving a speckled rash-like appearance
Petechiae can look like small red freckles, but their underlying cause can sometimes be much more serious than a simple cosmetic concern.
Clinical Features
Petechiae usually present as flat, pinpoint-sized spots. Because they’re essentially trapped blood, they won’t lighten or disappear when you apply pressure. Sometimes, many petechiae combine to form larger patches called purpura.
You’ll frequently see them on:
- The lower legs (due to gravity and circulation)
- The arms, abdomen, or even the face, depending on the cause
Unlike cherry angiomas, petechiae may or may not be asymptomatic. They can be accompanied by various systemic issues, depending on what triggers them.
Causes
Petechiae occur any time capillaries become more fragile or when blood-related disorders affect platelet count. Common causes include:
- Increased capillary fragility from age, nutritional deficiencies, or direct trauma.
- Thrombocytopenia (low platelet counts) is seen in illnesses like leukemia or aplastic anemia.
- Infections, such as meningococcemia or endocarditis, where bacteria or viruses can damage blood vessels and reduce platelet function.
- Vasculitis, which inflames blood vessels.
- Physical trauma, like intense coughing or excessive pressure that breaks small vessels.
Associated Conditions
Petechiae can pop up in several health contexts. While they’re not always a sign of a severe disease, it’s important to be aware of potentially related conditions:
- Autoimmune disorders that can affect platelet levels (e.g., lupus)
- Medications that reduce platelet production or function (e.g., certain anticoagulants)
- Nutritional deficiencies, like low vitamin C, potentially impacting blood vessel integrity
Not all cases are dire, but a sudden spread of petechiae warrants a thorough look to rule out anything serious.

Differentiating Cherry Angiomas and Petechiae
Onset and Evolution
- Cherry angiomas often develop gradually and remain in place indefinitely. You might notice them becoming slightly more raised or enlarging over the years, but they don’t vanish on their own.
- Petechiae usually show up suddenly. They may clear up once any underlying cause (like low platelets or infection) is addressed.
Blanching Test
- Cherry angiomas can partially blanch if you press on them gently, although they’re sometimes so red and vascular that blanching is minimal.
- Petechiae do not blanch. Because the blood has already leaked into the skin, pressing on them won’t push that blood out.
Associated Symptoms
- Cherry angiomas are typically asymptomatic. Aside from their color and possible slight elevation, you might forget they’re even there.
- Petechiae can come with other issues. If you have an infection, for instance, you might experience fever, chills, or body aches. If it’s related to a platelet problem, you could notice easy bruising, bleeding gums, or nosebleeds.
Keeping an eye on any additional signs or symptoms is crucial. This kind of detective work helps you figure out whether you’re dealing with something harmless or a scenario that calls for immediate medical action.
When to Seek Medical Attention
If you’re dealing with cherry angiomas, and they’re not causing any problems, you can often leave them alone. On the other hand, if you have persistent petechiae—or you’re simply unsure whether you’re looking at an angioma, a petechia, or something else entirely—it’s better to play it safe.
If you’re unsure whether a skin spot is a harmless cherry angioma or something more serious like petechiae, a professional evaluation is crucial. Ayana Dermatology & Aesthetics offers expert full-body skin exams to help you get answers quickly and confidently.
In particular, watch for:
- Sudden onset of numerous petechiae.
- Cherry angiomas that bleed frequently or have changed in size or color.
- Accompanying symptoms like fever, malaise, or unexplained bruising.
Early assessment can go a long way. If a simple test or exam reveals that the red spots are indeed minor, at least you’ll have that peace of mind. If something more complex is at play, timely treatment can make all the difference.
Conclusion
Cherry angiomas and petechiae are both vascular lesions, yet their causes, appearances, and potential implications vary greatly. Cherry angiomas are benign growths that often stick around for a lifetime, typically only removed for aesthetic reasons or if they bleed often. Petechiae, meanwhile, are tiny spots resulting from small bleeds under the skin, which can sometimes signal an underlying medical condition. The safest approach is always to get a professional opinion when new or suspicious lesions appear.
When it comes to cherry angioma vs petechiae, remember that each scenario requires its own form of care. If there’s any question about what you’re dealing with, don’t hesitate to connect with skilled professionals in the Fort Lauderdale area.

FAQs about Cherry Angioma vs Petechiae
Are cherry angiomas a sign of an underlying health condition?
In most cases, cherry angiomas are simply benign growths linked to aging or genetics. They aren’t usually associated with serious health issues. However, if a large number appears rapidly, it can sometimes signal underlying factors such as hormonal changes or chemical exposure. If you notice a rapid surge of new lesions, consulting a dermatologist is a smart move.
Can petechiae be a side effect of medications?
Absolutely. Certain medications, like anticoagulants or drugs that influence platelet function, can lead to petechiae. These small spots may emerge when your platelets aren’t able to clot blood properly. If you suspect your medication is contributing to skin changes, talk to your doctor about possible alternatives or dosage adjustments.
How can I distinguish between a cherry angioma and a petechia at home?
A quick method is the blanching test. Press the lesion gently with a clear surface like a glass slide or even a finger. A cherry angioma may blanch a bit, revealing a lighter color, whereas petechiae do not blanch. Also, cherry angiomas are often raised and dome-shaped, while petechiae are flat and do not protrude from the skin.
Is treatment necessary for cherry angiomas?
Not necessarily. Most are harmless and can be left alone if they don’t bother you. However, if they’re in a location prone to irritation or if you’d like to remove them for cosmetic reasons, several outpatient treatments are available. Laser therapies, electrocauterization, and cryotherapy are common options.
What should I do if I notice a sudden onset of multiple petechiae?
If many new petechiae appear quickly—especially accompanied by symptoms like fever, bruising, or bleeding—it’s important to seek medical evaluation right away. There can be serious conditions that reduce platelet counts or damage blood vessels, and prompt diagnosis makes a major difference in proper treatment.
