The thyroid pathology was sent for reanalysis and showed 2 foci of follicular variant of PTC in a background of chronic thyroiditis as well as Langerhans cells (positive staining for S-100, CD1a, langerin, and CD68), consistent with concurrent LCH, PTC, and Hashimoto's thyroiditis within the thyroid. The gene discussed is CD68; the disease is Hashimoto thyroiditis.
