While the last area resembled a WTL-PTC (Warthin Like-Papillary Thyroid Carcinoma) (Figure 2A), the first component was similar to the diffuse sclerosing variant of PTC (Figure 2B).

We detected an intense immunoreactivity for cytokeratin 19 and Galectin-3 (Figure 3) in every neoplastic cell and a focal positivity for p40 in few neoplastic cells in sclerosing areas (Figure 4).
