Melanoma
Introduction

Malignant tumor of melanocytes. Several variants exist.

Clinical signs
  • no special site of predilection, more often on face and back (men) or lower extremities (women)
  • I. superficial spreading melanoma (SSM): most common form: slowly growing brown macule
  • II. lentigo maligna melanoma: develops from lentigo maligna (which is in situ melanoma of elderly people) when invasion appears
  • III. nodular melanoma: red, brown, black tumor, often ulcerating and/or bleeding
  • IV. acral lentiginous melanoma: nails, fingers, palms, soles
  • special clinical variants: melanoma of mucous membrane, conjunctina, amelanotic melanoma
  • ABCD rule: A  —  asymmetry, B  —  border, C  —  colour, D  —  diameter
