We can see aggregated brown clods, so as per the attached algorithm we need to manage this as probably melanocytic. Given the asymmetry and uncertain history excision was required.
Histology showed a seborrhoeic keratosis.
Dermoscopy is not perfect, but on a different day this could have been a melanoma. There remains no doubt that this lesion needed excising rather than observation.
