RT Journal A1 Kantor J T1 Plica polonica: Confusion, confabulation, and the death of a disease JF Archives of Dermatology JO Archives of Dermatology YR 2012 FD May 1 VO 148 IS 5 SP 633 OP 633 DO 10.1001/archdermatol.2012.443 UL http://dx.doi.org/10.1001/archdermatol.2012.443 AB For half a millennium, physicians and scholars have investigated the etiology of and therapeutic options for a disease known as plica polonica, described originally by Johannes Schenck von Grafenberg1 in 1584 as an irreversible plaiting of the hair accompanied by lice, headache, mutilating arthritis, scoliosis, and onychogryphosis. Referred to variously as trica incubarus (devil's hair), weichselzopf, and plica polonica, early descriptions of this entity focused as much on its perceived spiritual roots as its medical origins.
