Lumps On Edges of Ears

My 4yrs old jack "Bruno" has strange hard lumps on the edges of his ears which can't be removed by washing!! I have removed one of them with skin & hair!! Bruno was recently @ his vet & was treated for all the usual things like worms/ticks/etc.......I am worried as I have only noticed these lumps in the last few days & fear they could be there awhile!!

His ears (inside) are totally clean with no foreign bodies or smells!! & Bruno has no other lumps anywhere else on his body!!
