To examine the characteristics of <jats:styled-content style=\"fixed-case\">EPF,<\/jats:styled-content> with respect to age, sex, race, and chronology, published in case reports to date, we queried PubMed using the following terms: (\u201ceosinophilic pustular folliculitis\u201d [All Fields] <jats:styled-content style=\"fixed-case\">OR<\/jats:styled-content> \u201ceosinophilic folliculitis\u201d [All Fields]) <jats:styled-content style=\"fixed-case\">AND<\/jats:styled-content> (\u201c1965\/1\/1\u201d [<jats:styled-content style=\"fixed-case\">PDAT<\/jats:styled-content>]: \u201c2013\/12\/31\u201d [<jats:styled-content style=\"fixed-case\">PDAT<\/jats:styled-content>]).

The PubMed search produced 275 citations containing 358 cases of <jats:styled-content style=\"fixed-case\">EPF<\/jats:styled-content> (224 men, 132 women, and two of unspecified sex); these cases involved classic <jats:styled-content style=\"fixed-case\">EPF<\/jats:styled-content> (101 Japanese and 81 non\u2010Japanese), <jats:styled-content style=\"fixed-case\">IS<\/jats:styled-content>\/<jats:styled-content style=\"fixed-case\">HIV<\/jats:styled-content> (4 Japanese and 85 non\u2010Japanese), <jats:styled-content style=\"fixed-case\">IS<\/jats:styled-content>\/non\u2010<jats:styled-content style=\"fixed-case\">HIV<\/jats:styled-content> (4 Japanese and 20 non\u2010Japanese), and I\u2010<jats:styled-content style=\"fixed-case\">EPF<\/jats:styled-content> (4 Japanese and 59 non\u2010Japanese).
