Current treatment modalities vary and often result in only temporary remission. There are no reports of surgical therapies for FD. Here, we describe FD treatment using surgical excision and second-intention healing aided by guarded high-tension sutures.Methods: Five patients (one woman and four men) with histologically confirmed FD were treated by surgical lesion excision. All wounds were allowed to heal via second-intention. Guarded high-tension sutures were employed to minimize tissue tears while aiding and guiding wound contraction.Results: All wounds healed with a 47– 83% spatial contraction of the maximum wound diameters. Three patients healed entirely by second-intention, while two required a minor skin graft to close the wound completely. No disease recurrence was noted at 10– 24 months.Conclusion: Surgical excision with second-intention healing aided by guarded high-tension sutures effectively treated small and extensive FD lesions with no recurrence at long-term follow-up. To our knowledge, this is the first report of successful surgical treatment of FD.Plain Language Summary: Current treatment modalities of folliculitis decalvans, including steroids, antibiotics, and isotretinoin, are suboptimal, typically resulting in recurrence following the withdrawal of treatments. In this case series, we report a first account of treatment success of refractory folliculitis decalvans using surgical excision with second intention healing aided by guarded high-tension suturing. The outpatient procedure resulted in long-term remission at 10– 24 months follow-up.Keywords: folliculitis decalvans, treatment, surgical treatment, alopecia, primary cicatricial alopecia, acne keloidalis nuchae, lichen planopilaris, surgery, therapy, second intention healing, tension sutures, scaring alopecia, hair loss
