Therapeutic options for perifolliculitis capitis abscedens et suffodens: A review.

Perifolliculitis capitis abscedens et suffodiens (PCAS) is a chronic skin inflammatory disease characterized by relapsing folliculitis and painful, fluctuant abscesses, sinus tracts, and scars. The treatment of PCAS is challenging and clinical practice varies a lot, and how to choose the best treatment for PCAS is a real problem for clinicians. We reviewed articles providing treatment options for patients with PCAS in different databases. Dermatologists may find this review helpful to meet the challenges of PCAS management, but there is still a lack of authoritative guidelines. In the future, more robust randomized control trials are needed to determine the best treatment for PCAS.
