We have studied one undifferentiated (embryonal) sarcoma of the liver (USL) by fine‐needle aspiration cytology (FNAC) and have correlated the cytologic findings with those seen in the histologic sections. The main cytologic and immunocytochemical features were: cellular aspirates, mesenchymal clusters, disparity in individual cell size (small round cells, and multinucleated giant cells, sometimes bizarre), absence of biliary pigment, AFP‐negative and vimentin‐negative tumor cells, AFP‐negative and PAS‐positive hyaline globules, and apoptotic cells. Only immunostaining for alpha‐1‐antitrypsin, alpha‐1‐anti‐chymotrypsin, and carcinoembryonic antigen were positive in tumor cells in histologic sections. The differential diagnosis should be carried out with rhabdomyosarcomas, hepatoblastomas, malignant fibrous histiocytomas, and poorly differentiated hepatocarcinomas. We think that the cytologic features observed in this case, evaluated both in the appropriate clinical context and in the light of the laboratory findings, may permit the correct diagnosis of this infrequent liver tumor. Nevertheless, more cases need to be studied to assess the reliability of our findings. © 1995 Wiley‐Liss, Inc.
