Livedo reticularis is due to dilation of capillary blood vessels and stagnation of blood within these vessels producing a mottled discolouration of the skin.
- Rash sometimes associated with connective tissue disease
- Chronic headaches and intermittent dizziness
- Blue/red discolouration of the skin with a characteristic network pattern
- Occurs chiefly on the trunk, legs and forearms.
- It worsens with cold but usually persists even when the skin is rewarmed.
- The colour change is due to dilatation of, and stagnation within, the capillaries and minute venules in the affected areas.
- There is a great diversity of causes leading to diversity of clinical manifestation.
- Idiopathic livedo reticularis occurring predominantly in young adults and middle-aged females may be associated with ulceration of the leg in a minority of cases.
