Granulocyte-macrophage colony-stimulating factor for perianal hidradenitis suppurativa : Report of a case

Perianal hidradenitis suppurativa is a chronic inflammatory disease associated with significantly high morbidity, which severely affects the quality of life of those patients suffering from it. We describe a 46-year-old patient with extensive, severe gluteal and perianal PHS of 28 years duration. Repeated wide excisions, fistulotomies, treatments with hyperbaric oxygen, and finally a diverting colostomy were unsuccessful. A new form of treatment with repeated perilesional injections of granulocyte-macrophage colony-stimulating factor, in conjunction with surgical procedures, was performed with excellent results.
