Clinical and Histopathologic Study of Pilomatricoma in Iran between 1992 and 2005

Abstract:  Pilomatricoma (calcifying epithelioma of Malherb) is a tumor of hair follicle matrix cells and is almost always benign. In this study we reviewed the clinical and histopathological features of 45 cases of pilomatricoma during 13 years (1992‐2005). Although few malignant transformations have been reported in other studies, no evidence of malignancy or aggressiveness is observed in this study.
