The cell pattern of fibroadenoma was observed by aspiration and operation smears obtained from 13 cases.All these were diagnosed histologically as fibroadenhma.The preparations were stained by M-G-G method.
Usually, each cell from fibroadenoma case was round or oval in shape and small in size.It was rare to find nuclei over 20μ.
Regular piling of cells was commonly found in these cases.
Sometimes, the smears of fibroadenoma with remarkable epithelial proliferation had abundant cell materials and mild loose cohesion similar to the smears of cancer cases.
Large and variable size of nuclei, irregular piling of cells, fusion of cell border and cell inclusion were common observations in cancer cases. But these findings were scarcely observed in fibroadenoma cases.
