Seborrhoeic wart. Light micrograph of a section through a seborrhoeic wart in skin tissue. Also known as seborrhoeic keratosis and basal cell papilloma,this is a common benign skin tumour. It arises from the epidermal layer of the skin. The central round area is a cyst within the papilloma. The cyst consists of concentric layers of keratin,a tough skin protein.
