Concurrent Hidradenitis Suppurativa, Inflammatory Acne, Dissecting Cellulitis of the Scalp, and Pyoderma Gangrenosum in a 16‐Year‐Old Boy

Abstract
We report the case of a 16-year-old boy who presented to our clinic with concomitant hidradenitis suppurativa, inflammatory acne, dissecting cellulitis of the scalp, and pyoderma gangrenosum. Recent reports describe the co-occurrence of pyoderma gangrenosum, acne, and hidradenitis suppurativa. This case further expands the spectrum of concomitant pyoderma gangrenosum and dissecting cellulitis of the scalp.
