Pack and LeFevre,1 in a study of 19,129 tumor cases, of which 2,564 were benign growths, found that lipomas included 4.3 per cent of all benign tumors. Adair,2 reporting the regional distribution of 352 lipomas in 134 patients, had a frequency of from 4 to 5 per cent of all benign tumors. Of these, nine cases (6.7 per cent) were multiple lipomas. Adair included a case presenting 160 distinct tumors. Of the 352
