Lichen planus and papillomas are generally benign conditions

• Cryptococcus neoformans is a heavily encapsulated yeast. The capsule is a major virulence factor and is essential for the fungus to cause disease in humans.
• It is a significant human pathogen known to cause cryptococcosis, which frequently manifests as meningitis, particularly in immunocompromised individuals.
• Melanin production is a crucial virulence factor for C. neoformans, helping protect it from host defenses.
• C. neoformans is classified as a basidiomycete yeast.
