Clinical Features

Initially, hidradenitis suppurativa begins as a painful deep erythematous nodule usually in the axilla or groin. The inflammatory nodule may resolve on its own or develop into a sterile abscess that may open to the surface and drain. Such a lesion may persist and periodically drain, develop a sinus tract and continually drain, or heal with scarring. New lesions may develop in the same area and interconnect. Open comedones, which normally are not present in these body regions, may be seen. Comedones with multiple openings are characteristic of hidradenitis suppurativa. Scarring may be pitted, bridging, or hypertrophic ( Fig. 240:4). The extent of involvement is variable with some patients experiencing only localized intermittent lesions with minimal scarring and others with continuously active disease in the axilla, groin, intergluteal cleft, and buttocks.
