The calcifying epithelioma of Malherbe in children: a 15-year experience

The calcifying epithelioma of Malherbe is a benign tumour of hair-cell matrix, from which it derives its name of pilomatrixoma. Although a relatively benign lesion, diagnostic difficulty may arise and the definitive diagnosis of these firm subcutaneous tumours is often made only after histological analysis. Over 15 years, 46 patients have had 51 lesions excised. A brief historical overview is presented.
