Angiomyolipoma of the liver is a rare benign tumor that's composed of variable mixtures of adipose tissue, smooth muscle and thick-walled blood vessels. We report here on the imprint cytologic features of a hepatic angiomyolipoma in a 47-year-old man. The smears showed spindle and epithelioid tumor cells in clusters, trabeculae and single cells. The spindle cells had elongated, cigar-shaped nuclei with finely granular chromatin and fibrillary cytoplasm. The epithelioid cells had round nuclei with a moderate amount of cytoplasm. Any adipose tissue was not found. Immunohistochemically, both the spindle and epithelioid cells revealed cytoplasmic positivity for smooth muscle actin and HMB-45.
