Mottled skin

Mottled Skin

Mottled skin, also known as Livedo reticularis, is a skin condition characterized by patchy, irregular skin discoloration. The skin appears to have purple or red discolorations in a net-like pattern, often more noticeable on the legs, arms, and trunk.

Causes

Mottled skin can be caused by a variety of factors, including:

• Cold exposure: This is the most common cause of mottled skin. The skin may become mottled in response to cold temperatures as a way to preserve body heat.
• Vasculitis: This is an inflammation of the blood vessels that can cause mottled skin.
• Antiphospholipid syndrome: This is an autoimmune disorder that can cause blood clots and mottled skin.
• Shock: In severe cases, mottled skin can be a sign of shock, a life-threatening condition that requires immediate medical attention.

Symptoms

The primary symptom of mottled skin is a distinct, net-like pattern of reddish or purplish discoloration on the skin. Other symptoms may include:

• Cold skin: The skin may feel cold to the touch.
• Pain: Some people may experience pain in the affected area.
• Ulcers: In severe cases, skin ulcers may develop.

Treatment

Treatment for mottled skin depends on the underlying cause. If the mottling is caused by cold exposure, warming the skin can help. If it's caused by an underlying medical condition, treating that condition should improve the mottling. In some cases, vasodilator drugs may be used to improve blood flow to the skin.
