by this technique , lesional mast cells from patients with adult systemic mastocytosis had a significantly larger mean cytoplasmic area ( 53.3 microns2 ) , nuclear size ( 20.4 microns2 ) , and granule diameter ( 0.81 micron ) when compared with mast cells from adults with nonsystemic mastocytosis ( 36.3 micron 2 , 15.4 microns2 , and 0.67 micron , respectively ) and normal age-matched control subjects ( 34.4 microns2 , 14.1 microns2 , and 0.67 micron , respectively ) .
