A rare case of malignant melanoma of the Lacrimal Sac

Abstract

Malignant melanoma is a malignancy of the pigment

- producing cells known as melanocytes. The organ usually

affected is the skin. While melanoma accounts for roughly

4% of all skin cancers, it is responsible for more than 77%

of skin cancer deaths. Mucosal melanoma is a rare entity

compared to cutaneous malignant melanoma.

Mucosal malignant melanoma of the head and neck

represents approximately 8% of all melanomas that develop

in the head and neck and generally behaves far more

aggressively than cutaneous melanoma.
