This lesion on the back of a lady looks clinically like a Seborrheic Keratosis and the dermoscopy picture also suggests that when looking at the lower edges. A closer look reveals some lines of pigment dots and also dot blood vessels making this likely to be a Pigmented Intraepidermal Carcinoma which is what the report has confirmed. Below is the closer view of the pigment.

Same lesion as above - Pigment lines present in the centre of the picture

The pigment in this lesion is arranged in a random pattern of small dark brown clods and this is more likely to be seen in a Pigmented Basal Cell Carcinoma. Once again, that is the diagnosis
