Scanning electron microscopic analysis (SEM) of 50 pre-selected breast
aspirates was performed after light microscopy and cytomorphological
evaluation, SEM analysis of these aspirates revealed the presence of m
icrovilli (mv), microprojections, blebs and irregular contours in mali
gnant cells. Benign cells were regular, globular and smooth, SEM provi
ded additional morphologic data which if used in conjunction with ligh
t microscopy can assist in reaching a correct diagnosis.
