Description: Comparison of two pigmented lesions Note the blue grey ovoid nests and the arborising vessels of the pigmented BCC and the crypts and milia of the seborrhoeic keratosis. Harald would describe these as orange and white clods.

History: This lady had multiple seborrhoeic keratoses on her back but sometimes a lesion sticks out as a bit unusual. This was the juxtaposition of a deeply pigmented BCC and a seborrhoeic keratosis.
