[Neurotrophic ulcerations in the area of the trigeminal nerve in Wallenberg's syndrome]

Abstract

We report two new cases of neurotrophic ulceration of the trigeminal nerve associated with Wallenberg syndrome, and we present the six cases published since the first description of the neurologic syndrome, in 1895. This peculiar etiology supports the argument for the dominant physiopathologic hypothesis: ulcerations due to multiple microtraumatisms caused by the thermoalgic anesthesia.
