Successful treatment of stage III hidradenitis suppurativa with botulinum toxin A.

A 41-year-old obese Native American woman presented with hidradenitis suppurativa (HS) after failing all available treatment options. Her HS was more pronounced in the axillary and groin regions (Hurley stage III) and was a major source of her pain and a barrier for home exercise and aquatic therapy. She received a botulinum toxin A injection every 3 months (four times thus far), which has significantly helped alleviate her pain and curb the progress of her HS by resolving abscesses and healing draining sinuses.
