This image depicts a very large, pigmented cutaneous lesion that was diagnosed as a congenital nevus, and in this case, otherwise known as a giant melanocytic nevus. Note the variable coloration, and slightly irregular border of this nevus.
Additional Information:
Congenital, or giant melanocytic nevi, are characterized by the following criteria:

- These lesions affect 1 in 30,000 – 100,000 individuals

- They are greater than 20cm in diameter

- These nevi often occur in association with smaller congenital nevi

- These lesions present a lifetime risk of MM estimated to be 6 – 10%

- The long term follow-up care is usually challenging

- When possible, a staged prophylactic removal is recommended

- The greatest risk of developing MM occurs before the age of 5yrs, with the next greatest chance occurring
   between 5 – 10 years of age
