BackgroundHidradenitis suppurativa (HS) is a chronic relapsing inflammatory skin disease with multiple treatment options that have been used with mixed results.ObjectivesTo evaluate the effectiveness, safety and tolerability of intralesional photodynamic therapy (I-PDT) in the management of HS. Also, to assess the effect of this technique on the different areas treated.MethodsCase series of 38 HS patients treated with I-PDT between 2011-2015 following a standardized protocol to assess response at the treated areasResults29 patients achieved a complete response, while persistence was noted on 8 cases and only 1 suffered a recurrence. Difference between basal (median 28.5) and final (0) Hidradenitis Severity Score showed a significant reduction of 24.5 points (p<0.001, 95% OR 19.5-31). Basal (median 10) and final (1) Dermatology Life Quality Index scores reached a reduction of 10 points (p<0.001, 95%OR 8-12). Complete response was achieved in 68.2% of armpits, 88.5% of groins, 88.9% of buttocks and 100% of other locations. 18 out of 38 patients needed only a session to achieve a complete response, while maintaining a good tolerability.ConclusionWe believe that I-PDT might be an alternative treatment option for localized HS lesions, achieving a high rate of remission with an adequate maintenance of response i and few complications.
