Hepatoblastoma, although rare, is the most common primary malignant neoplasm of the liver in children. In this paper we describe a case of hepatoblastoma with unusual cytologic features and present the histologic, immunocytochemical and ultrastructural features of this neoplasm. A 7-month-old girl presented with a large hepatic mass and metastatic nodules in both lungs. Intraoperative biopsy revealed a hepatoblastoma. Aspiration biopsy yielded a highly cellular aspirate with cords of pleomorphic cells embedded in a mucoid matrix. Histologic sections showed a diffusely infiltrative neoplasm composed of sheets and cords of highly pleomorphic cells. The neoplastic cells stained strongly positive for cytokeratin CAM 5.2 and AE1 and focally positive for alpha-fetoprotein, ferritin, carcinoembryonic antigen and vimentin. Ultrastructurally, the neoplastic cells had abundant intercellular junctions and intracytoplasmic aggregates of intermediate filaments. A mucoid matrix, to our knowledge, has not been reported as a finding on aspiration biopsy. This patient presented with pulmonary metastases, and thus we think the mucoid matrix may be a marker of a more aggressive variant of hepatoblastoma. This case illustrates additional cytologic features of hepatoblastoma and the usefulness of aspiration biopsy in the rapid diagnosis of this rare tumor.

Breast cancer markers (TM) are mainly useful for monitoring the course of disease after diagnosis and first line treatment with the control options of primary treatments early recognition of reactivation and efficiency control of palliative treatment. The best single and established marker is a polymorphic epithelial mucin of the MUC-1 family the prototype of which is CA 15-3 (successive markers: MCA, CA-549, TAG-12, CAM 26/29) followed by CEA with lower diagnostic sensitivity and specificity and TPA/TPS reflecting more the proliferative activity. Besides former TM combinations of CEA with one or more less specific markers (e.g. PAM, CRP, beta 2m, ferritin, GCDFP, HCG, total or boney AP, gamma GT), more recent studies recommend the use of fewer markers such as TPA/TPS + CEA or CA 15-3, CA 15-3 + CEA or MCA, CA M26 + CA M29, TAG12 + CA 15-3 + MCA and CEA + CA 15-3 + ESR.
