Like liver spots, seborrheic keratoses are seen more often as people age. [4] The tumours (also called lesions) appear in various colours, from light tan to black.
Dermatographic urticaria is sometimes called "skin writing", as it is possible to mark deliberate patterns onto the skin. The condition manifests as an allergic-like reaction, causing a warm red wheal to appear on the skin. As it is often the result of scratches, involving contact with other materials, it can be confused with an allergic ...
