ABSTRACT
BENIGN SKIN TUMOURS Benign epidermal lesions Common benign epidermal lesions include actinic keratoses, solar lentigos, seborrhoeic keratoses, dermatosis papulosa nigra in black skin, and skin tags (fibroepithelial polyps). Epidermal cysts may be quite large (Chapter 3) or tiny, then usually referred to as milia. Benign melanocytic naevi are derived from melanocytes that reside in the basal layer of the epidermis (Chapter 10).
