Nuclei of affected neurons are pyknotic, karyorrhectic, or losing border definition within the cytoplasm.
Features of apoptosis include a pyknotic nucleus that dyes brown with uneven coloring and is typically ring shaped.
Reduction in hepatocyte cell size however, is attributed to the loss of glycogen deposits and fat leading to cell death due to necrosis and cell atrophy indicating the reduction in metabolic activity of hepatocyte resulting to pyknotic nuclei.
Degenerative changes include cytoplasmic rupture, loss of nuclear shape, elongation or indistinct segmentation of granulocyte nuclei, loss of chromatin definition (appear to have liquefied), pyknotic nuclei (necrobiotic forms), degranulation and cytoplasmic vacuolation.
The histological expression of the tumor corresponds to a firm nodule of spindle-shaped cells with pyknotic nuclei arranged in bands that build longitudinal fibrils; the ones that are transversally cut are arranged in palisade with a fibrillar hyalinized core forming Verocay bodies (Figure IE).
Necrotic changes accompanied with fatty changes were also found in some areas; in which the hepatocytes had pyknotic nuclei with strong eosinophilic cytoplasm or severe destruction (Fig.
In the ITG group, pyknotic spiral ganglion cells were seen in light microscopy examination.
Distinguishing pyknotic cells or degenerating cells from true mitotic figures can be challenging.
The nuclear abnormalities including binucleated cell (BN), pyknotic nuclei (PN), nuclear buds (NBUDs), condensed chromatic (CC), karyolysis (KL) and Karyorrhexis (KR) have found to be associated with the exposure to tobacco smoke, drugs as well as alcohol.
Hepatic sections of rats treated with APAP showed multiple large foci of degenerated hepatocytes with vacuolated cytoplasm and pyknotic nuclei, in addition to congestion of hepatic blood sinusoids (Fig.
Some of their nuclei appeared pyknotic and karyorrhectic compared with the control group (Figure 2c).
2] exposure produced pronounced hepatic histopathology; evidenced by histological alternations in the liver, including focal necrosis with hepatocyte vacuolization and swelling, pyknotic nuclei, and dilation of central vein and sinusoids.
