Capillaritis
Capillaritis is a condition where inflammation of the tiniest blood vessels in the skin results in leakage of blood and petechiae (tiny spots of bleeding under the skin that do not blanche when you press on them). Capillaritis is frequently found in individuals who stand for long periods of time, such as people who are on their feet a lot for work. Capillaritis can come and go intermittently.
Who's At Risk?
Capillaritis is seen more commonly in adults, especially men, but it can occur in older children and teenagers as well.
Signs & Symptoms
The most common location for capillaritis is the legs, but it can also occur on the trunk and arms. Capillaritis never occurs on the face. Capillaritis may appear as:
- Brown-red or dark brown petechiae in darker skin colors or light red or dark red petechiae in lighter skin colors.
- Color variations in the lesions may be seen at different stages of development.
- Petechiae can merge to form petechial patches.
Self-Care Guidelines
No self-care is necessary.
Treatments
If capillaritis is diagnosed, your medical professional may prescribe a topical steroid cream or lotion.
Visit Urgency
Although capillaritis itself is a harmless condition, other conditions can also cause petechiae. Seek medical evaluation for a rash with petechiae or another unknown rash.
