Central white clods from a keratin plug. This rpaidly growing lesion is likely to be a Keratoacanthoma but could also be a Squamous Cell Carcinoma
This lesion is on the lower leg and the white lines show the SCC extending well out to the edge of the picture. This one will require a large excision
SCC on the forearm. The bubbles in the picture are from the gel that is applied to allow better visualisation of the blood vessels
This 62 yr old lady came to see me a few weeks after a pigmented lesion on her face had been treated with cryotherapy. From 10 o'clock around to 5 o'clock, you can see a grey area of pigmentation. This creates a diagnostic problem from the point of view of a dermatoscopist. Grey pigment is in the dermis and therefore it has the potential to be abnormal and can indicate the development of a melanoma. In this case the grey pigment is uniform and without chaos the chances of a melanoma are small. I chose to leave the lesion and check it again in three months and the picture below was taken three months. later
Now you can see the final result after healing.
The next picture shows more detail
The main area of interest here is from 1 o'clock to 3 o'clock where you can see a uniform arrangement of pigment that has been taken up by macrophages in the process of repair. This is normal. The original lesion is a Solar Lentigo and where you see regression like I have described above it is called Lichen Planus Like Keratosis (LPLK). Regression can occur either as a result of cryotherapy like in this case or as a normal autoimmune response where ones own immune system tries to remove the lesion.
Anyone who is enthused by looking at skin lesions is welcome on this blog. My aim is that we all learn from each other.
