We observed dermal melanocytes running in parallel with collagen fibers in the peritumoral stroma of a basal cell epithelioma. The dermal melanocyte contained many free mature melanosomes. They frequently showed an intimate contact with elastic fibers and were surrounded by an extracellular sheath with elastic fibers. These cells may have occurred due to the activation of dormant dermal melanocytes following the appearance of basal cell epithelioma, which may have been derived from a nevoid tumor originating from dormant, latent embryonic foci.
