Multiple odontogenic keratocysts in a patient with type II (mitis) Ehlers-Danlos syndrome.

Ehlers-Danlos syndrome (EDS) is now considered to be a heterogeneous collection of fundamentally distinct disorders. The many and varied sub-types of EDS have been distinguished using clinical, genetic and in some cases biochemical criteria and this has important implications as regards prognosis and the prediction of inheritance patterns. The major clinical features of EDS are reviewed, with particular emphasis placed on the possible complications encountered in the practice of oral surgery. A case of Type II mitis EDS is described, that presented with multiple odontogenic keratocysts.
