Anyone have experience with scrotal wounds?

Anyone have experience with scrotal wounds? I have a patient with a sizeable (4x3x0) anterior scrotal wound with significant slough, induration to the "west" of that wound with tiny areas of oozing and slough and a perineal area near a gluteal fold that is raised, indurated and opens and closes with exudative purulence. I have not received any diagnoses other than ulcer. I believe there is something more going on. Thanks for any insite.
