You may have noticed that a lot of my skin cancer reels feature EARS. This simply reflects clinical practice in Australia. Unfortunately, we see HEAPS of skin cancers on ears, which on average don’t seem to get a lot of SPF love.
Seborrhoeic keratoses are incredibly common and benign sun barnacles, but we always check them out as you can get cancer arising within them. The most common associated cancer is some version of squamous cell cancer. Which is not all that surprising when you come to realise that the cell of origin for seborrhoeic keratoses and squamous cell cancer is the same - the humble keratinocyte. In this case we have exactly that - early squamous cell cancer arising in a sebK.
A BENIGN proliferation of keratinocytes is a seborrhoeic keratosis. A MALIGNANT proliferation is a squamous cell cancer. Sometimes your body shows off and does both variations in the same location.
I like to tell patients that there is no future-proofing in a skin check. A spot that is benign today can grow a cancer in it in future. So, if a spot I have checked for you before subsequently changes, you are NOT entitled to assume it is fine. They didn’t give me a crystal ball along with the Masters degree🔮.
