Özet
OBJECTIVE: To determine the fine needle aspiration biopsy (FNAB) findings in hepatic Echinococcus multilocularis. STUDY DESIGN: FNAB and tru-cut liver needle biopsy were applied in 14 hepatic E multilocularis cases. Cytologic smears were stained with May-Grünwald-Giemsa and periodic acid-Schiff (PAS) stain. Tissue sections were stained with hematoxylin-eosin (HE) and PAS stain. RESULTS: In tissue sections, homogeneous, thin, cystic structures of various dimensions strongly stained with PAS. Mucoid material was stained with PAS in the cystic structures. Wide, coagulative necrosis was observed in all cases. In some cases there were foreign body-type giant cells at the periphery of the lesion. In all the cytologic smears there were an intense necrotic ground, PASpositive hyaline cuticular structures and mucoid globules; in some cases there were foreign body-type giant cells. CONCLUSION: The above cytologic characteristics are basic diagnostic criteria for FNAB of E multilocularis. © 1997 The International Academy of Cytology Acta Cytologica.
