Mentioned in this book, one hundred articles on PubMed, even a redirect on Wikipedia, but of course no entry for it, much less the horrific story involved. Like why so many children died, horribly, or were crippled. A multiple country endemic "disease" caused by giving infants and children toxic mercury, and it isn't notable enough to have an article on Wikipedia?
You won't find the story of Pink Disease on Wikipedia. You will find a ridiculous paragraph called Infantile Acrodynia, which in no way actually matches the historic record. See this paper for more info Or any of my multiple blog posts about it.
(edit May 2015) There is now an article on Acrodynia, but no story of Pink disease.
