Thirty\u2010five patients who underwent surgery for a parotid mass were included in the study. The maximum shear elastic modulus of the mass was measured by SWE. Pleomorphic adenomas were histopathologically subdivided into stroma\u2010poor, intermediate\u2010stroma, and stroma\u2010rich tumors based on the relative proportion of stromal to cellular components.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The maximum shear elastic modulus values of the pleomorphic adenomas ranged from 12.6 to 291.9 kPa (mean \u00b1 SD, 120.9 \u00b1 92.8 kPa). The Friedman test revealed a statistically significant relationship between the stromal amount and maximum shear elastic modulus (<jats:italic>P<\/jats:italic> &lt; .001). Stroma\u2010poor adenomas (mean, 32.3 \u00b1 27.7 kPa; range, 12.6\u201381.1 kPa) were softer on SWE than stroma\u2010rich adenomas (mean, 174.1 \u00b1 48.4 kPa; range, 92.7\u2013217.2 kPa; <jats:italic>P<\/jats:italic> = .009).
