title: Amitosis in human adrenal cells.
abstract: Adrenal pieces obtained from 3 female and 2 male patients showed morphological figures of amitosis in adrenal zona reticularis cells. Such aspects were observed in both normal and hyperactive adrenals. Nuclei appeared constricted, heavily stained, with coarse chromatin, sometimes scattered among cytoplasmic organelles, but never marginating in crescentic caps. Cleavage of the cells originated two halves with a nucleolus in each pole. Binucleated cells were also seen in zona reticularis. The meaning of amitosis in human adrenal is discussed.
