Hello Rachel:

I apologize for the delay in responding to your query.

The skin report provided shows presence of malignant melanocytes.... Pigment producing cells in the skin. These are present single and in groups and go to a depth of 1.6 mm. The cells are actively dividing (6 mitosis ) hence are aggressive. Special stains like Ki67 confirms this.

It appears to be malignant melanoma... Cancer of melanin producing cells in the skin.

The important point to clarify is if the lesion was removed completely and that the margins are clear. If so then you would just require regular follow up. If not remaining lesion would need to be excised.

Your doctor will advise on protection for sun and when to follow up visit
