One study available in the 'Journal of the American Academy of Dertmatology' indicates that of 23 patients, 21 of the study subjects with biopsy-proven FD found great relief with the Biologic Humira, citing picture and documented evidence. It is not yet known the full cause of the disease, but recent findings suggest an autoimmune component. In the vast majority of patients the bacteria Staphylococcus Aureus is present and has had minor success with a combination therapy of Clindamycin and Rifampin, although the rate of relief after this therapy is stopped is unknown. To date, Humira shows the best long-term therapeutic relief for patients with this painful disease that causes pustules, hair loss and excessive inflammation. </p><p>Source: <a rel="nofollow" class="external free" href="https://www.jaad.org/article/S0190-9622(22)00358-9/fulltext">https://www.jaad.org/article/S0190-9622(22)00358-9/fulltext</a> </p> <div class="mw-heading mw-heading2"><h2 id="Epidemiology">Epidemiology</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Folliculitis_decalvans&action=edit&section=4" title="Edit section: Epidemiology"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>This disorder was first described by <a href="/wiki/Charles-Eug%C3%A8ne_Quinquaud" title="Charles-Eugène Quinquaud">Charles-Eugène Quinquaud</a> in 1888.
