From: Hepatic adrenal adenoma-rare tumor on right lobe of liver: a case report and literature review
The tumor had clear boundaries, enveloped with a thin fibroid membrane and surrounded with some liver tissues. The tumor was composed of different proportions of bright and dark cells of acidophilic cytoplasm. These cells were distributed in cable or chests, accompanied by abundant blood vessels and sinusoidal structures (organ-like structures). The cell nucleus was round or oval and presented slight atypia. Aberrant cell nuclei were observed, and mitosis was rare (A. HE × 50; B, HE× 400)
