Perifolliculitis Capitis Abscedens et Suffodiens

A 25-year-old black heterosexual man presented with tender nodules, abscesses, and patchy alopecia on his scalp for 1 year. Despite a 1-month course of oral tetracycline, his condition did not improve. He had oily abscesses with purulent drainage on the scalp and small facial acne cysts. Blood tests, including those for HIV and syphilis, were normal. Repeated cultures were performed, but the document does not specify the results.
