For Malaria Prevention During The Vietnam War The US Army

For malaria prevention during the Vietnam War the US Army used chloroquine plus primaquin. I was a Captain Battalion Surgeon in Xuan Loc, Vietnam 1967. My adverse reaction was an initial episode of Lichen Planus, oral. Erosive outbreaks remain ongoing to the present 2016; periodic outbreaks anywhere on my body including: nipples, areolas, genitals, legs, arms, scalp. Erosive patches develop secondary skin infections and leave disfiguring scars and compromised immunity. How often do you see this in Vietnam Veterans?
