A novel topical agent in the treatment of seborrheic keratoses: A proof of concept study by clinical and dermoscopic evaluation

Abstract

In this proof of concept study, 50 lesions from 15 patients with multiple seborrheic keratoses (SKs) were treated with a novel aqueous solution containing nitric acid, zinc and copper salts, and organic acids (acetic, lactic, and oxalic acid). Treatment consisted in the application of an amount of the solution sufficient to obtain a whitening/yellowish reaction. Application of the nitric–zinc solution was performed every other week until clinical and dermoscopic clearance or crust formation, for a maximum of 4 applications. Efficacy evaluation was performed at 8 weeks (T1) and 6 months (T2). All subjects, who reported no or minimal discomfort during and after the application of the solution, completed the study. At T1, a complete clinical and dermoscopic resolution was observed in 37 lesions after an average of 3 applications/lesion (range 2–4). A partial response, with minimal persistent residual spots, was detected in the remaining 13 lesions. All patients with complete clearance showed no relapses at a 6-month follow-up (T2). The positive preliminary results indicate that this novel solution may represent a promising alternative option for SKs especially in patients not keen or eligible to undergo invasive tissue-destructive procedures.
