Spontaneous regression of a facial malignant melanoma.
We report a case of a head and neck melanoma fulfilling the criteria for spontaneous regression of the primary tumor. The melanoma originated within a pretragal nevus. Histological examination of the surgical specimen revealed regressive changes within the nevus but no demonstrable melanoma. This brings to a total of 14 the number of patients with documented regression of a primary melanoma.
