Pilomatricoma (calcifying epithelioma): a study of 100 cases in El Salvador.
We found 100 cases of pilomatricoma by reviewing the files of the Department of Pathology of the National Medical Center of El Salvador for a period of 58 months (January 1975 to October 1979). All diagnoses were confirmed by biopsies. The tumor was most frequent between 11 and 20 years of age. The mean age was 11.2 years, the youngest patient being of 1 year, 8 months and the oldest being 74. Both were boys. By sex, the feminine dominated with a ratio of 2.4 to 1 (71% women and 29% men). In only two cases were the tumors multiple (two tumors in each one), and neither eruptive pilomatricomas nor association with other neoplasias or myotonic dystrophy were found. Most of the tumors occurred in the cephalic segment (29%).
