Rodent ulcer. Coloured light micrograph of a section through human skin showing a rodent ulcer,a skin cancer otherwise known as basal cell carcinoma. The cancerous lesion is coloured red (upper left). The surface of the skin is at top. Healthy tissue is green. At the skin surface the rodent ulcer is separate from healthy skin. This carcinoma forms from basal cells of the epidermis,the wavy line at centre left. The whole epidermis is cancerous,while the dermis beneath and some healthy tissue has also been invaded by malignant cells. Rodent ulcer is a common skin cancer in fair-skinned people. Overexposure to sunlight is thought to cause this cancer | |
