Pilomatricoma, often called calcifying epithelioma of Malherbe, is a tumor with differentiation toward hair cells, particularly hair matrix cells. It presents as a firm, deep-seated nodule that is covered by normal or pink skin. It is occuring usually as a single lesion which is most commonly found on the face, neck, or proximal upper extremity. Multiple lesions are quite unusual, comprising only 2-3.5% of cases. A 32-year old man had 3 subcutaneous nodules on the both upper extremities. Histological findings of the lesion showed the typical pattern of pilomatricoma. We presented herein one case of multiple pilomatricoma with the review of literatures.
