Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating disease, affecting mainly women, especially in their second and third decades of life. Its most common incidence is in the axillary, inguinal, perianal and inframammary regions. Its complications include chronic fistulizing processes, with involvement of important adjacent structures, such as the sacrum and coccyx, the anal sphincter, urethra and great-caliber vessels, such as the groin vessels. The proportions of some cases of HS requiring extensive surgical procedures at several moments and the application of flaps and grafts, justify unusual cases reports, like this one. The authors present a case of extensive involvement of the perianal and gluteal regions, which required extended resection with flap in the first approach and fistulectomy in a second surgical moment, with good result for the patient.
