ABSTRACT
Dermatologists and dermatopathologists employ a dazzling array of terms to describe pigmented cutaneous lesions. There are melanomas of the lentigo maligna type, superficial spreading type, acral lentiginous type, and nodular melanoma. The criteria to describe regression in cutaneous melanoma were delineated nearly 25 years ago. Borderline pigmented cutaneous lesions (between melanomas and nevi) are described. Aside from acquired nevi, there are congenital nevi of the small and garment type, dysplastic nevi, Spitz nevi, blue and cellular blue nevi, and many others.
