title: A sheep in wolf's clothing.
abstract: Most are familiar with the biblical warnings about false prophets presenting as the wolf in sheep's clothing, but in this issue of Blood, Mansoor and colleagues expose a sheep in wolf's clothing by shining a bright light on a newly described benign disease previously pretending to be a very bad malignancy, and doing so quite convincingly.
