[Perianal pyoderma].

Perianal pyoderma (hidradenitis suppurativa-acne conglobata) is a chronic disease which in its progressive form cannot be treated by conservative methods. Extensive suppurative foci must be radically excised incl. all systems of fistulas right down to the fascia and the defects which develop are allowed to heal per secundam or after several weeks they can at a different period of time be covered by a skin transplant. The authors present their 30-year experience with surgical treatment of 39 patients. Treatment was in all instances successful after radical surgical excision. All these patients have fully recovered as regards work capacity as well as social aspects.
