Bateman's disease.

Bateman's disease is characterized by the presence of purpuric eruptions involving the extremities. Semi-thin sections and morphological pictures evidence the damage this illness can cause to the elastic fibres. After passing in review the various pathogenetic theories, the Authors consider this disease an expression of discrasic alterations of an amyloidosic character of all the vessel structures, of severe senile elastosis and of the lack of fibrin-like material.
