Dermatology and skin disease in the American Civil War.

The Civil War happened at the end of the medical dark ages or, conversely, at the beginning of the modern medical era.

Entities discussed include the army itch/camp itch phenomenon, sexually transmitted diseases, scurvy and nutritional disorders, smallpox and spurious vaccination, and hospital gangrene.
