Lesion of concern Clinic

  • The purpose of this clinic is to give a fast access to an expert who will immediately assess a specific lesion of concern for the patient.

  • The doctor will tell the patient the diagnosis, giving peace of mind in cases of benign lesions, or organizing a quick excision in cases suspicious for malignancy.

 

  • When to suspect melanoma?

    • The ABCDE acronym can help distinguish a melanoma from a normal mole:

      • A. Asymmetry: the lesion is irregular in shape or pattern.

      • B. Border: the border or outline of a melanoma is usually irregular.

      • C. Colour: there is variation in colour within the lesion.

      • D. Diameter: the lesion is usually greater than 6 mm across. However, suspect lesions of smaller diameter should also be investigated.

      • E. Evolving: the lesion changes over time (size, shape, surface, colour, symptoms e.g. itch).

  • When to suspect a non-melanoma skin cancer?

    • The EFG acronym can be of help:

      • E. Elevated: the lesion can appear as a small, round and raised lump on the skin. Colour may be uniform throughout the lesion and may be black, brown, pink or red.

      • F. Firm: the lesion feels firm to the touch.

      • G. Grows: a nodule that has been growing progressively for more than a month should be assessed as a matter of urgency.

  • Any lesion that displays the ABCDE or EFG features over a period of more than one month should be investigated. If nodular or thick melanoma is suspected, diagnosis should not be delayed, and urgent referral to an expert or immediate excision is recommended.
