Regressing and Regressed Melanoma

  • Guido Massi
  • Philip E. Leboit


Malignant melanoma frequently undergoes extensive, subtotal or even complete regression. Although the regression is a continuous biological and morphological process, we describe the two different histological stages separately, for didactic purposes:
  • regressing melanoma with an “active” inflammatory infiltrate;

  • regressed melanoma in its terminal fibrotic phase.
