Seven cases of spontaneous and complete regression of primary melanoma with metastasis are reported. The ages of the patients ranged from 33 to 68 years. There were five men and two women. All patients had had a cutaneous pigmented lesion that underwent a two-stage course: enlargement and darkening, then flattening and depigmentation. Within a few months to 4 years after depigmentation, regional node(s) developed and were removed, confirming the diagnosis of melanoma. An histopathologic examination of the primary sites failed to show residual malignant cells and characteristic features. Primary melanomas that have completely regressed are easily overlooked.
