+Comment:
+Stains/IHC confirm the morphologic findings; the tumour stains as follows:
+POSITIVE: calcitonin, CEAp, synaptophysin, CD56, TTF-1 (focal, moderate), congo red (confirms the presence of amyloid).
+NEGATIVE: thyroglobulin, CDX2.
+</pre>
+===Micro===
+The sections show cells of intermediate size without apparent nucleoli, moderate eosinophilic cytoplasm, arranged in nests, focally associated with amorphous acellular cotton candy-like material.
+The cotton candy-like material has a light apple-green appearance when polarized.
