Background: Hidradenitis suppurativa (HS) is rare in childhood, with only 2% of cases in patients younger than 11 years. It is a chronic, recurrent, debilitating condition for which no universally effective treatment has been developed. We present five cases of children with HS diagnosed between the ages of 6 and 11 years.
Methods: Patients were treated with oral finasteride 1 to 5 mg/day. All had entered puberty at the time of treatment initiation. All had normal laboratory results before starting treatment. The maximum duration of treatment was 24 months.
Results: Four patients were female. Two were overweight. Three had been previously treated with oral antibiotics, and two of these with oral isotretinoin, with partial or no improvement. Overall improvement of the disease was observed in all patients, with a reduction of the frequency and intensity of the flares. No adverse effects were observed or reported during treatment.
Conclusion: Treatment of HS can be challenging. The options available include antimicrobials, immunosuppressants, hormonal therapies, lasers, and surgery. The authors report the largest series of children with HS treated with finasteride. The results support the use of finasteride as monotherapy for the treatment of this disease in children. Further studies are necessary to fully understand the role of this drug in the management of this disease.
