Successful Treatment of Coexistent Acne Fulminans and Severe Hidradenitis Suppurativa with Adalimumab.

The coexistence of hidradenitis suppurativa (HS) and acne fulminans (AF) has only recently been reported in the literature. We present a case of a 17-year-old man who presented with a 2 years history of severe acne and HS. He was initially started on oral clindamycin and rifampicin for 3 months with no clinical improvement. Acne lesions became worse with the presence of nodules and necrotic ulcers, while weight loss, low-grade fever, back and knee pain, and psychological distress were noted. We prescribed adalimumab in its standard dosing regimen. Remission of AF was achieved in 3 months, whereas adalimumab has not been as effective in treating the HS lesions. Its dosage was increased to 80 mg weekly and more than 80% clinical improvement of HS lesions was obtained in 2 months. The patient maintained on this dosage till this day and efficacy is sustained. TNF-α inhibitors are considered an effective option in the treatment of HS, while it has been also suggested as a treatment option in AF. Our patient was successfully treated with adalimumab. Since the coexistence of HS and AF has a devastating emotional effect on the patient, there is an urgent need to implement therapeutic approaches.
