Mallory-Weiss vs. Boerhaave's

[dr.kirk]

Can anyone differentiate mallory-weiss from boerhaaves? I understand they are both ruptures of distal esophagus and seen in alcoholics/bulemics. Boerhaaves has complication of hamman's mediastinal crunch but I havent seen any questions that talk about the crunch sign so Im wondering how else I can tell the diff between the two? (or am I just reading into this?!)
Thanks..

mallory weiss is a mucosal tear, boarhaave is total rupture of the esophagus
