Very rarely seen in children,<unk>  and non-bullous<unk>  most commonly occurs in people 70 years of age and older. Its estimated frequency is seven to 14 cases per million per year, but has been reported to be as high as 472 cases per million per year in Scottish men older than 85. At least one study indicates the incidence might be increasing in the United Kingdom. Some sources report it affects men twice as frequently as women, while others report no difference between the sexes. Many mammals can be afflicted, including dogs, cats, pigs, and horses, as well as humans. It is very rare in dogs; on average, three cases are diagnosed around the world each year.
