Furthermore, physical examination confirms a thyroid pathology; and work-up makes the diagnosis of Hashimoto's thyroiditis most likely due to the presence of anti-TPO (positive in 90% of Hashimoto's thyroiditis cases). Hashimoto's thyroiditis is known to be associated with Non-Hodgkin's lymphoma (NHL).
