Gemistocytic astrocytes with abundant eosinophilic cytoplasm and eccentric nuclei.........
Note the dense eosinophilic cytoplasm and eccentrically displaced nucleus . Gemistocytes are frequently found in other fibrillary astrocytomas and oligodendrogliomas. Some authors require at 20% of tumor cells to be gemistocytic before using the designation of gemistocytic astrocytoma. This
tumor appears to be composed of an almost pure population of gemistocytic cells.

This beautiful picture nicely illustrates Dallas criteria for myocarditis, which require both myocyte damage and an inflammatory infiltrate. Myocyte damage is characterized by scalloped myocytes with inflammatory cell encroachment (arrow), attenuated fibers (arrowhead), or remnants of myocytes (“bare nuclei”) (*).

Intratubular germ cell neoplasia(IGCN):
Beautiful picture showing cells (within seminiferous tubule) having enlarged nuclei, prominent nucleoli, and clear cytoplasm along the basal aspect of a seminiferous tubules lacking spermatogenesis. Sertoli cells are displaced toward the lumen. Intratubular germ cell neoplasia, unclassified type. To read more click on- http://patho.medtut.net/2016/04/06/intratubular-germ-cell-neoplasia/
