What is this skin lesion?
This is a melanoma in situ. This means that the malignant cells are confined to the tissue of origin, the epidermis, and have not invaded through the basement membrane into the dermis.
What are the clinical features of this disorder?
It is not usually possible to be certain that a melanoma is in situ, although the clinical and dermoscopic appearance can be helpful. The pigmented lesion often appears to be a simple freckle at first. It may take several years to enlarge enough to come to the patient's attention. Look for irregularity in the shape of the lesion and variability in colour. If in doubt, cut it out!
