How to use the Atlas

  • Step 1

    Choose one of the four groups and open it.

  • Step 2

    Use the photos as a reference. Visual similarity does not confirm a diagnosis.

  • Step 3

    If the skin lesion bothers you or causes concern, book an in-person appointment.

  • Step 4

    If removal is necessary, this will be decided after a doctor's assessment.

Photos and descriptions of skin lesions

Open one of the four groups. The descriptions provide guidance but do not replace doctor's assessment: a similar-looking photo does not confirm a diagnosis.

If a skin lesion causes concern

Do not try to make a diagnosis based on a photo alone. If the skin lesion changes, causes discomfort, or raises concerns, start with an in-person appointment. A doctor will assess the lesion and recommend the next steps.

Frequently asked questions about the Atlas

No. The photos help you understand what different types of moles look like, what to look out for and how to phrase a question for your doctor. However, they cannot provide a diagnosis. A medical assessment of the mole, whether it can be removed and the expected cosmetic outcome of removal requires an in-person appointment by a doctor.

It is best to book an appointment if the skin lesion changes, itches, hurts, bleeds, grows, or develops a crust. This is especially important if it resembles any of the examples in groups 3–4.

Choose a group based on the description, open it, and find a photo that looks similar to your skin lesion. Use it to prepare for a discussion with your doctor, not to make a diagnosis yourself.

Patients have two appointment options: a mole assessment and examination, or a mole assessment and removal. The first option is priced at the standard general practitioner consultation fee. The second includes both the assessment and removal of the skin lesion. Both appointments begin with an examination to assess the type and location of the skin lesion, the condition of the skin and the expected cosmetic outcome.

The doctor determines whether a histological examination is needed after examining the skin lesion. Histological examination can accurately determine the nature of the tissue when it is necessary to rule out malignancy or clarify the diagnosis.

The Atlas was created under the supervision of Finnish dermatologist Professor Raimo Suhonen.
