Cell lysis from immune response

*** I am not seeking medical advice ***

A recent poison ivy rash made me curious as to what exactly is happening when a rash "weeps".  So far I've discovered that urushiol changes proteins in your skin prompting T Cells to call their brothers the macrophages and others to destroy your otherwise healthy skin.  During the immune response, the rash "weeps".  My question is, is the weeping a result of the cell lysis?  Without putting the contents of whatever is coming out of the rash under a microscope, would I be far off in assuming that the fluid coming out of the rash is lysate or cytoplasm and cellular material?  Just curious.  

Thanks in advance :)
