Dermal naevus (mole)

A mole is a common and harmless lump or spot on the skin, consisting mainly of melanocytes (pigment cells). A dermal mole is often soft and raised.

Also known as

Dermal mole, intradermal naevus, intradermal mole, mole, melanocytic naevus, intradermal cellular naevus

Symptoms and signs

  • Lump or nodule on the skin, usually soft.
  • Surface may be smooth or rough and wart-like. The colour may be the same as the surrounding skin, or brown to dark brown.

Risk factors

  • Family history: relatives with many moles
  • Prolonged and/or intense sun exposure as a child or teenager
  • Immunosupressant medication

Prognosis / outcome

Dermal moles are normal and harmless. They do not develop into skin cancers. Sometimes a raised dermal mole will become dry or irritated or it may be rubbed or scratched. This may cause the mole to become sore, change colour or consistency, or bleed.

Progression

A dermal naevus may form as part of the life cycle of a normal mole. The mole may start as flat and smooth and gradually become raised.
