Poorly differentiated features, tumoral necrosis, Tumors with neuroendocrine (tumor or carcinoma) and adenocarcinoma components of 30% each, Some use size criteria < 5 mm as a definition for hyperplasia and > 5 mm is the minimum size necessary to diagnose a NET, Some may diagnose NET when grossly there is a polyp / nodule regardless of size in the absence of other explanatory findings, Other criteria have been proposed for microscopic proliferations: if there is nodular growth of ECL cells > 150 microns or if there is a conglomeration of nodules, signs of microinfiltration or new stroma, then the lesion has been proposed to be classified as dysplasia or Tis, Ki67 and mitotic figure count, whichever is higher, Ki67 and mitotic figure count, whichever is lower.
