Eczema vaccinatum is a type of vaccinia infection, that may occur in people with atopic dermatitis (eczema) or other skin diseases.[2] Symptoms include a sudden onset of crops of small blisters, typically at sites of skin problems.[2] Typically there is also a fever and swollen glands.[1][5] Onset is 5 to 12 days post exposure.[3]

While it may occur due to direct smallpox vaccination with vaccinia; more often it occurs following spread from a household member who has had a recent vaccine.[2] While atopic dermatitis is a risk factor for the disease; it is estimated that if vaccinated, only one in a hundred would be affected.[4] The underlying mechanism involves extensive spread of the virus.[4] Diagnosis is usually based on exposure to vaccinia.[6]

Treatment is with vaccinia immune globulin (VIG) and potentially the antiviral medication cidofovir.[2][4] Prevention may include the use of the MVA-BN vaccine in those at high risk.[4] Scarring often remains after healing.[2] Without treatment around 35% die, and with treatment this is about 7%.[2]

Between 2002 and 2012 only one case was described in the United States.[4] In the United States in 1968 there were 66 cases following 14.5 million smallpox vaccinations, and 60 cases among several million contacts.[1] Males are affected twice as often as females.[3] The condition is believed to have been first described in 1882.[4]
