I'm not terribly knowledgable about Hashimoto's, but I do know that it can cause intermittent episodes of hyperthyroidism, and these can be associated with easy bruising.
Really, if this is a new symptom you should call your doctor. It may be that your thyroid is high, or it could be another condition that needs attention.
