Pilomatricoma in the Eyelid: A Case Report

The pilomatricoma (calcifying epithelioma of Malherbe) is a rare, benign, asymptomatic tumor arising from the hair follicular matrix cells. It is usually a solitary lesion and it is most commonly found on the face and upper extremities. This tumor can occur in patients of any age, but about 60% of pilomatricomas are found in those patients less than twenty years old. The radiologic features of this neoplasm have rarely been described in the literature; in particular, the CT findings of pilomatricoma originating from the eyelid have not been published in Korea. We report here on a case of pilomatricoma that occurred in 69-year-old female; she had a hard subcutaneous mass on her right eyelid with overlying bluish skin.
