What are these little red spots?
The most common formations on the arms, legs or torso are:
-
Petechiae – localized red, purple, or brown spots caused by broken capillaries; they do not disappear with pressure.
-
Red (cherry) angiomas – bright red, dome-shaped bumps formed from clusters of blood vessels.
-
Purpura – larger red or purple spots due to bleeding under the skin.
Although red angiomas are usually harmless and age-related, petechiae and purpura often signal something more serious, especially if they multiply rapidly or appear without visible trauma.
6 Possible Causes of Small Red Spots
1. Petechiae – a sign of a blood or platelet problem
-
Low platelet count (thrombocytopenia)
-
Infections (streptococcal, septicemia, viral diseases)
-
Autoimmune diseases (e.g., lupus, ITP)
-
Medications (anticoagulants, antibiotics, chemotherapy)
⚠️When to worry: If petechiae appear suddenly, spread quickly, or are accompanied by fever, fatigue, or easy bruising, seek medical attention immediately.
2. Red angiomas – usually harmless, but watch for changes
-
✅They are not dangerous.
-
✅Often increase with age
-
✅They can grow or multiply.
🔍When to see a dermatologist: If they start to bleed, change shape, or become painful, have them checked to rule out a skin tumor.
