(Created page with "'''Staining''': HE '''Organ''': Adrenal gland '''Description''': The whole slide is tumor except for a small part on the lower right side, where we can see normal adrenal cortex. The tumor cells show mild atypia and have eosinophilic cytoplasm and produce a pattern called “zellballen”, which looks like small nests. The nests are separated by a vascular network. The cells that seperate the zellballen are called sustentacular (supporting) cells. '''Diagnosis''': P...")
