Besides metastatic localization of GATA3-positive tumors in the nasal cavity, GATA3 expression may be seen in primary sinonasal neuroendocrine neoplasms, like ectopic pituitary neuroendocrine tumors/adenomas (PitNETs) [30] and paraganglioma [28, 29]. This evidence concerns the gene GATA3 and paraganglioma.
