The general method you're looking for is to add "patient" (or whatever term you prefer) as a factor in your design. So, if you denote tumor/normal by a factor called "status":
counts ~ status + patient
would likely be the formula you want. You could also allow an interaction if it makes sense for your dataset, by swapping an asterisk for the plus sign. You'll need to specify the individual patients in your dataframe, of course.
