Weedon and Strutton

 
"In this type (superficial spreading melanoma), there is proliferation of melanocytes singly and in nests at all levels within the epidermis and often the adnexal epithelium. This pagetoid growth pattern is sometimes referred to as "buckshot scatter" of melanocytes." Weedon D, Strutton G. In: Emmett AJJ, O'Rourke MGE. Malignant skin tumours. 2nd Edition. Edinburgh: Churchill Livingstone, 1991:72.
 

Brief Critique

 
The same changes are found in some Spitz's nevi and are not distinguishing of those nevi from melanoma.
