Abstract

In the First Edition of the World Health Organization (WHO) Histological Typing of Skin Tumours (1974), malignant melanoma was classified into four categories:
  1. 1.

    Malignant melanoma

     
  2. 2.

    Malignant melanoma arising in precancerous melanosis, including Hutchinson’s melanotic freckle

     
  3. 3.

    Malignant melanoma arising in a blue naevus

     
  4. 4.

    Malignant melanoma arising in giant pigmented naevus

     
Most melanomas, according to this classification, would belong to categories 1 and 2, the essential histological difference between the two types being the presence of “precancerous melanosis including Hutchinson’s melanotic freckle” in the epidermis adjacent to the invasive neoplasm in category 2, whereas in category 1 there was no such adjacent component.
