Description: Small dark papule lower back
History:
Routine skin check of a male in late 60s with this pigmented lesion on the lower back. Not aware of it. Clinically it stood out because it was much darker than his other nevi.
Histology showed mainly an in situ melanoma with an invasive component of 0.4 mm and a lot of dermal melanin in melanophages
