Regressed primary malignant melanoma with regional metastases.
Eleven cases of metastatic malignant melanoma with a completely regressed primary melanoma have been described. An additional case is reported here. The patient had melanoma metastatic to femoral lymph nodes and a pigmented lesion on the lower part of the leg. The pigmented lesion showed fibrosis, increased numbers of capillaries, and a band-like infiltrate of melanophages in the dermis. No residual melanoma was found. The findings in this case are similar to those previously reported.
