BACKGROUND: @entity4177 is the most common primary @entity99 in @entity1 . The literature contains few examples of fine needle aspiration (FNA) cytology of these @entity5 . CASES: A 5-month-old and 4-month-old underwent ultrasonography-guided FNA for the preoperative investigation of hepatic masses. The smears were stained with May-Gr  nwald-Giemsa and Papanicolaou stain. Alcohol-fixed smears were used for immunocytochemistry. All smears revealed cells with round/oval nuclei, prominent nucleoli and vacuolated cytoplasm, arranged in groups and acinar structures. The groups were embedded in a @entity4494 . @entity160 was positive in all, and @entity2277 was positive in some @entity5 cells. The cytologic findings resembled the histologic counterpart in one case, and the other case agreed with the clinical/radiologic prediagnosis. Immunocytochemistry was supportive. CONCLUSION: FNA cytology can be diagnostic in many other @entity5 as well as @entity4177 . Detailed descriptions of cytomorphologic features of @entity4177 will help FNA to be used confidently on these @entity5 .
