[Acne inversa (hidradenitis suppurativa): early deetection and curative surgery]

Acne inversa (synonyms are hidradenitis suppurativa, pyodermia fistulans sinifica) is a chronic inflammatory disorder of the terminal hair follicles of the intertrigines. Abscesses and fistules develop mostly in both axillae, in the anogenital region, and under the breasts. The disease is common, but the right diagnosis is often missed. Local incision gives only a short relief of pain. The therapy of choice is wide local excision. We report on 12 patients with acne inversa who were surgically treated from 1991-1999 in our department. Surgical results and patient satisfaction were assessed on an average of 4.2 years. In all, 20 excisions in the axillae and 5 excisions anogenital were done. Seven patients were treated preoperatively with isotretinoin over at least 2 months. All patients could move their limbs without trouble. The cosmetic result was good in nine patients and three expressed dissatisfaction. Nine patients did not develop new lesions in the treated area. Three patients had new inflammations in both treated and previously uninvolved and therefore not resected regions. Wide local excision gives very good functional and cosmetic results. It usually heate long-lasting disease for nearly disabled patients. Isotretinoin reduces the disease activity and allows radical surgical treatment.
