Pachyonychia congenita type 2
Type of disease: Rare conditions
See Pachyonychia Congenita. Pachyonychia congenita Jackson Lawler type is listed incorrectly as a separate type of Pachyonychia Congenita. The former classification system of PC Type 1 and PC Type 2 has been replaced by a more correct, genetically-based classification (see McLean, Journal of Investigative Dermatology, May 2011).
