Immunohistochemistry of interleukins. (A) IL-1β presented a diffuse, homogeneous and cytoplasmic pattern of expression in thyroid cancer cells. (B) IL-10 was seen as strong brownish expression in both nuclei and cytoplasm of malignant cells. (C) IL-17A presented a focal cytoplasmic expression among thyroid cancer cells. (D) IL-23 expression was observed in cytoplasm of malignant cells. All panels evidenced that stromal structures (eg. collagen, colloid and vessels) lack expression of immune markers.
