Nuclear receptor subfamily 4 group A member 3 (NR4A3) immunohistochemistry in acinic cell carcinoma and secretory carcinoma in cytology specimens (×100). Cell block preparations from fine-needle aspirates from acinic cell carcinoma (A, B) and secretory carcinoma (C, D), a key entity on the differential diagnosis, were stained with H&E or immunostained with NR4A3. Nuclear NR4A3 was seen only in acinic cell carcinoma cases but not in secretory carcinoma cases.
