Among TPO antibody\u2013positive patients, comparing thyroid cancerous nodules in patients with heterogeneous glands to those with homogeneous glands, there was no significant difference in any sonographic characteristic except the margin of the nodule, which was more often irregular or poorly defined in heterogeneous glands and more often smooth in homogeneous glands (<jats:italic>P<\/jats:italic>&lt; .05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Sonographic features of thyroid cancer are similar in patients with and without Hashimoto thyroiditis.
