The plica polonica of the 21.century

We describe a young man presenting with dreadlocks. There are remarkable si milarities with the so called plica polonica, that historically had been tr eated with long courses of mercury. Apparently very important in the 18th c entury, the interest for this hairdisorder appears to be lost in specialize d medical literature. In contrast dreadlocks, a recent hairstyle are freque ntly encountered. Lack of other sources various websites provide dermatolog ists with answers to questions regarding complications. Fortunately a simpl y haircut is today treatment enough.
