   This, and the related noun grume, are doctors’ (and in particular   
   pathologists’) jargon for a blood clot or any viscous fluid or mass of fluid.   
   but being aware of its existence in English may be helpful for those   
   non-doctors who are familiar with French le grumeau (lump, clot) or Italian   
   il grumo (clot (whether milk or blood)).   
      
   It’s an unremarkable borrowing from late Latin, OED describes [ad. late L.   
   grumus little heap, hillock;]. I can’t find any convincing further etymology   
   beyond that.
