It sounds likely that they are diseased. In that case, it may be best not to eat them since it is not known what exactly is infecting the fruit. Even if the spotted areas are removed (cut at least 1 inch further out from the affected area), unblemished areas may still harbor fungus, bacteria, or viruses that may cause trouble, depending on the pathogen. Quality will likely not be as good either, perhaps affecting taste etc. Unfortunately, when in doubt, throw it out.
