A case of a 51 year old man with a plantar malignant melanoma is reported. The tumor had clinical and histologic features of lentigo maligna melanoma, but its biologic activity was that of a more potently malignant tumor. Electron microscopic observation reveales features similar to that of lentigo maligna melanoma, but not inconsistent with that of superficial spreading melanoma. A consideration of our case and of previous reports suggests that there is a relationship between the biologic potency and the site of involvement of lentigo maligna melanoma and that such lesions on relatively non‐pigmented areas such as the palms, soles, mucous membranes, and nail beds should be treated as having a highly malignant potential.
