Nuclear grooves are dark, basophilic “lines” in the nuclei of the tumor cells. Nuclear pseudoinclusions are eosinophilic inclusions inside the nuclei of the tumor cells. Ground glass nuclei are nuclei that are so pale that they are almost white. Psammoma bodies are collections of calcium that occur in areas of cystic degeneration.
