Because of the neurotropism of Lyme disease, speculative websites and articles and even peer-reviewed journals have purported causal associations between Lyme disease and several neurodegenerative disorders, including Alzheimer disease, amyotrophic lateral sclerosis (ALS), multiple sclerosis (MS), and Parkinson disease (6-11).
Neurotropism, which is defined by some as extensive endoneural and perineural invasion, and as Schwann cell-like differentiation of tumor cells by others, can also be seen.
It also seems that the neurotropism of the H5N8 virus was the key factor contributing to death in these migratory birds of 3 species.
It is also important to recognize that spindle and desmoplastic melanomas have higher propensity for neurotropism, thus resulting in high local recurrence.
pseudomallei collected in the Northern Territory, Australia, during October 1989-October 2012 (7), we sought to determine whether strains isolated from patients with neurologic melioidosis (neurologic isolates) showed higher virulence levels and neurotropism than isolates from patients with nonneurologic melioidosis (nonneurologic isolates) after respiratory and percutaneous exposure.
Invasive growth, including neurotropism, lymphatic-vascular invasion, or invasion of soft tissues (eg, skeletal muscle, bone, and others), is often identified.

Desmoplastic melanoma (Figure 5) is best classified as a variant of spindle cell melanoma and is characterized by a fibrous stroma with a tendency to local infiltrative growth and recurrence, as well as neurotropism.
