Tiny petechiae red dots of capillaritis initially resemble scattered cayenne pepper spots just below your skin’s surface. Continued blood leakage creates a flat red patch. And in time, your blood patches turn brown and then eventually fade.
Capillaritis caused blood patches commonly occur on your lower legs, although is sometimes seen on trunk and upper extremities. But never your face.
The precise cause of capillaritis is unknown. However, your capillary inflammation may be associated with:
- viral infection
- long periods of standing
- cutaneous T-cell lymphoma
- skin hypersensitivity reaction
- purpuric clothing contact dermatitis
- reaction to medication ~ salicylates, NSAIDs
