Giant verruca vulgaris presenting as a neurotrophic foot ulcer

The most common factor associated with neurotrophic ulcers is either a peripheral or central somesthetic deficit, such as may occur in peripheral neuropathies, myelodysplasia, syringomyelia, sciatic nerve injury, spinal cord injury, tabes dorsalis, and most commonly, in the peripheral neuropathy of diabetes. Distribution of the ulcers indicates a mechanical factor in development. Here, three patients with an unusual type of neurotrophic ulcer, giant neurotrophic verruca vulgaris, are presented.
