S ummary . Cells were obtained from the peripheral blood of a patient with marked non‐leukaemic eosinophilia. Transmission electron microscopy (TEM) showed typical mature eosinophils. The surface architecture of eosinophils by scanning electron microscopy (SEM) shows that most were spherical with varying numbers of microvilli; a smaller proportion of cells had ridge‐like profiles, small ruffles and occasionally blebs. The surface features of the eosinophil thus resemble most lymphocytes and this finding must be considered when leucocyte populations are examined by SEM.
