rosacea-like demodicidosis

Earlier this year Brady Barrows proposed a sixth subtype for rosacea: Rosacea Demodicidosis thinking that he was the first one to come up with this subtype, but apparently this has been known for some time. In doing a Google search it has been found that this came up as far back as 1932 according to an article published in California Medicine in 1963 by Samuel Ayres, Jr., MD in Los Angeles.

Here is a small part of the article:

As early as 1932 Ayres and Anderson called attention to a type of rosacea which they felt was caused in large part by extraordinarily heavy infestation by the mite, Demodex folliculorum, and it was pointed out that the demodex type of rosacea was a further development or complication of an entity that had been described and named by the present author two years previously under the title "Pityriasis Folliculorum (Demodex) ."l Since that time a number of publications have appeared on the subject as well as an exhibit at the thirteenth annual meeting of the American Academy of Dermatology and Syphilology in 1954. The most recent publication concerning the pathogenic role of Demodex in the production of pityriasis folliculorum (Demodex) and acne rosacea was Ayres and Ayres' summary of 30 years' experience with these two commonly unrecognized entities. Both conditions were referred to as demodicidosis. Inasmuch as the authors' attempts to describe and segregate a particular type of acne rosacea as being caused wholly or in large part by Demodex has led to confusion and to the erroneous statement that the authors have claimed that all cases of rosacea are caused by Demodex, it was felt that a new term should be coined and that rosacea of the Demodex type should henceforth be referred to as "rosacea-like demodicidosis."
