You stated that you do not have lupus. However, Levido reticularis is one of the common skin diseases seen with Lupus. There are several auto-immune diseases that have this issue as a common symptom. Levido Reticularis is a condition in which dilation of capillary blood vessels and stagnation of blood within these vessels causes mottled discoloration of the skin. It is described as being reticular (net-like) cyanotic (reddish blue discoloration) cutaneous discoloration surrounding pale central areas. It occurs mostly on the legs, arms and trunk and is more pronounced in cold weather.
You did not say if your condition is secondary or perhaps Sneddon's syndrome which is a form of idiopathic livedo reticularis with systemic involvement i.e. internal blood vessels are affected, most commonly in the brain, eye and heart.
Secondary is when the condition may be a sign of vasculitis (inflammation of the blood vessels- also a common symptom in auto-immune diseases like Lupus) or of obstruction of the vessel by some circulating material. The following conditions may be responsible for secondary:
Vasculitis: livedoid vasculitis - polyarteritis nodosa - Lupus - Dermatomyositis -RA - lymphoma -Pacreatitis - TB.
Unfortuantely, there is no specific treatment for livedo reticularis. Rewarming the area in idiopathic cases or treatment of the underlying cause (if it is an auto-immune disease) of secondary livedo may reverse the discoloration. If the condition is due to systemic vasculitis, it can be treated with corticosteroids and immunosuppressants; doses and combinations will vary according to the seriousness of your condition and if there are internal organs involved. Serious organ dysfunction requires the use of corticosteroids and cyclophosphamide pulse therapy. Combining low doses of corticosteroids with methotrexate or azathioprine is a good option for maintenance treatment in these cases.
There is no effective treatment for generalized livedo reticularis in antiphospholipid syndrome or Sneddon syndrome. Skin lesions due to thrombosis can be treated with low doses of aspirin or antiplatelet therapy, although some cases may require coumarin anticoagulants.
I hope that this has been helpful to you. Please let me know if you need anything further!
