Cutaneous signs of malignant disease

Michael Liu, Ross StC Barnetson



Cutaneous manifestations of underlying malignancies are uncommon but easy to recognise when the physician is aware of them. Recognition means that the possibility of underlying malignancy can be considered and, where appropriate, investigated and treated.

Key Points

  • Paraneoplastic dermatoses may present in various forms and are associated with underlying malignancy.
  • Although uncommon, these cutaneous conditions can be easily recognised once the physician is aware of them.
  • Their recognition should prompt a thorough investigation for the presence of an underlying malignancy.
  • Recognition of these cutaneous conditions may enable early diagnosis and treatment of malignancy.
