Spontaneous regression of the primary lesion of a metastatic maligvant melanoma.
An atypical elderly patient with spontaneous regression of a primary lesion of malignant melanoma is presented. The 12 previously reported cases are also reviewed. The histological diagnosis of spontaneous regression of a melanoma can still be made after the regression appears to be grossly complete. All localized areas of depigmentation, or of scarring, should be biopsied when searching for an "occult" primary.
