To the Editor.—
The development of a cutaneous melanoma within a nevus spilus, or speckled lentiginous nevus, was recently reported in the Archives.1 A unique feature in that case was the presence histologically of intraepidermal melanocytic dysplasia within the "speckled" or hyperpigmented areas. The possibility that the melanocytic dysplasia was a predisposing factor for the development of the melanoma was considered. In the following case report, a melanoma developed within a zosteriform speckled lentiginous nevus that had histologic features that were similar to those described by Rhodes and Mihm.1 However, in contrast to previously reported cases,1-5 this patient subsequently developed metastatic disease that proved to be fatal.
