use of "and" and "or" with a "negative verb" ??


For the sentence "The squamous architecture is mature, without dysplasia or single-cell atypia." is the use of "or" incorrect (have a bunch of doctors that form sentences using "negative" verbs but use "or" in the last half of the sentence).  That is, shouldn't the article used here be "and" when you are trying to state that none of these things are found in the specimen.   Also, for example, they will dictate "The specimen is without abnormality, free of atypia or malignancy." and I believe that sentence should be written " of atypia and malignancy." to accurately state what they are trying to say (i.e., there is no atypia and there is no malignancy in the specimen).


Could I get the answer to whether or not the article "and" should be used instead of "or" when a negative verb is used, followed by a "list" of things that are being excluded.
