case_images: The breast CNB yielded the diagnosis of invasive pleomorphic carcinoma (Figure 1) with positive hormonal receptors (oestrogens 100% and progesterone 80%, Ki67 70%, HER-2 positive (3+) (Figure 2), CK19 positive, E-cadherin negative (Figure 3), and P63 negative.
case_images: Positive tumour staining for HER-2 (3+).

case_images: Positive staining for synaptophysin in more than 50% of the tissue permits the diagnosis of a neuroendocrine tumour.
