Objective:To investigate the surgical management of perifolliculitis capitis abscedenset (PCAS).Methods:From June 2015 to October 2018, 8 patients with PCAS were treated, aged 13-26 years, with an average age of 23 years. Hypepigmented plaques in size were from 0.5-4.0 cm. The operative technique was based on the complete excision of the entire diseased skin and subcutaneous fatty tissue, the fistula was explored using a probe, the seton was inserted through the remaining tract in a double-strand fashion, this double-strand elastic seton was then tied over itself without excessive tension. The wound was covered with absorptive dressing.Results:All the wounds in 8 patients healed primarily. All patients were followed up for 6 months and showed no recurrence after surgery.Conclusions:Perifolliculitis capitis abscedens et suffodiens scalp is a rare chronic suppurative skin disease, its etiology and pathogenesis are unclear, but related with follicular atresia, bacterial infection, immune factors, sex hormones, smoking and obesity. The treatment is difficult, including antibiotics, vitamin A acid, biological agents, photodynamic, laser and surgery. The disease is stubborn and refractory. The technique of wide surgical excision and loose setons drainage is an effective method for PCAS.
