MoleExpert Professional

Mole mapping software for health professionals

The Mole Expert Professional software helps to identify new pigment lesions or to detect the growth or darkening of lesions in follow-up images compared to baseline images. This tools is essential for the management of patients with an increased melanoma risk und a larger number of pigmented moles.

Medical background

The American Skin Cancer Foundation recommends that everyone practice monthly head-to-toe self-examination of their skin, so that they can find any new or changing lesions that might be cancerous or precancerous. [1]
In America Melanoma is the most common cancer among women 20 to 29 years of age. Intermittent sun exposure and severe sunburns, especially during childhood, and use of tanning beds have been associated with an increased risk of cutaneous melanoma. Prior melanoma is associated with an increased risk of a second melanoma. Patients with a strong family history of melanoma and multiple clinically atypical moles are at the greatest risk for cutaneous melanoma.[2]
Liu et al found in a third of melanoma a growth rate of 0.5 mm per month. The monthly growth rate for SSM (superficial spreading melanoma) was 0.12 mm, for the LMM (lentigo maligna melanoma) 0.13 mm and 0.49 mm for NM (nodular melanoma). The ABCD-rule could not be reliably confirmed for fast-growing melanoma [3].
In Austria the monthly growth rate of melanoma (area) was found to be 0.43 mm² (SD ±0.9) with a mean relative increase of 33.7% (SD ±50.2). The average size at baseline was 25.6mm² (SD±14.5) and 32.0mm² (SD±16.7) after follow-up. The authors conclude ‘Melanomas are growing significantly faster than nevi of the same patient‘. [4].
In another study the authors discuss: ‘As expected, the melanomas in our sample grew at different speeds. Some grew relatively fast with a horizontal growth rate of up to 21.6 mm² per year, others grew slowly or not at all.’ [5]

Mole Mapping

  • Surveillance program for early detection of melanoma
  • Chances for long-term survival are excellent, when melanoma is detected and treated early
  • Change in the size, shape, or color of an existing mole might be a sign for melanoma
  • Melanoma also may appear as a new, black, abnormal mole
  • MoleExpert Home is the software for skin self-examination
  • MoleExpert Pro is mole mapping software for dermatologists and health professionals


  • examination of skin lesions with a dermatoscope (special magnifier)
  • also referred as dermoscopy
  • technique is primarily used by dermatologists and health care professionals
  • allows inspection of skin and monitoring skin lesions suspicious of melanoma
  • MoleExpert Micro is dermatoscopy software for health professionals
