       Calcifying epithelioma (pilomatrixoma) is a relatively uncommon benign tumor. It usually presents as a slow-growing subcutaneous or intradermal nodule measuring less than 3 cm. In this report, we present a 20-year-old male with giant pilomatrixoma in the subauricular region. We performed en bloc resection of the tumor, which measured 12×9 cm. Histopathologically, this tumor did not show any malignant findings. There has not been any evidence of recurrence since the treatment.

Key words : calcifying epithelioma, subauricular region
