Aim The aim of the study was to utilize the so-called reversed Kobner phenomenon to treat psoriasis by dermabrasion.Background The background has been reports on long term remissions following other surgical procedures such as dermatomy or laser surgery.Methods 11 psoriatics with localized, chronic heavily infiltrated plaques, which had not responded sufficiently to topical treatment with steroids and/or ditranol or tar, were treated with dermabrasion, using a diamond fraise.Results All treated lesions healed within 3-4 weeks without recurrence with the exception of a 0.5 0.5 cm minor recurrence in one patient. The observation period has been from 6 months to 5 years.Conclusions For this particular group of patients we can recommend dermabrasion as a suitable surgical therapy for psoriasis.
