How common is lentigo maligna melanoma in NZ?

  1. On the basis of data from the New Zealand Cancer Registry, 2256 invasive melanomas were identified in 2008, with around 10% of them being pathologically confirmed as maligna lentigo maligna.
  2. Although rates of the precursor, lentigo maligna, are not published by national cancer registries, it is believed to be the most prevalent type of melanoma in situ in New Zealand and Australia, where it is also found in high numbers.

How is lentigo maligna melanoma diagnosed?

It is possible to identify lentiginous malignant melanoma when the melanoma cells have spread into the dermis and deeper layers of the skin. When compared to the other kinds of in situ melanoma, lentiginous melanoma has a lower risk of transition into invasive melanoma (under 5 percent overall).

  1. When an invasive melanoma grows inside it, lentigo maligna does not become harmful; it only becomes potentially life threatening when it becomes a cancer of the skin.
  2. Review of the treated region, as well as a comprehensive skin inspection, are required for long-term follow-up to detect any new lesions of concern.
  3. If the lesion was invasive, it would be necessary to evaluate the lymph nodes in the surrounding area.

Is lentigo maligna curable?

Surgery is the only way to treat lentigo maligna. However, if the entire affected region is not entirely removed with the right surgery, some of them may progress to invasive melanoma status. It is therefore critical that it be removed with a rim of normal skin around the perimeter (an adequate surgical margin).

What is the difference between lentigo and lentigo maligna?

Lentigo maligna manifests itself as a discolored area of skin that grows or changes slowly over time. At first glance, it is frequently mistaken for a freckle or a benign lentigo. During the course of time, it becomes more distinct and uncommon, frequently developing to several centimetres in length over a period of several years or even decades.

What is a lentigo maligna?

Skin cancers such as lentigo maligna (LM) and lentigo maligna melanoma (LMM) are examples of this. They originate when melanocytes in the skin grow out of control and create tumors, which is how they get their name. Melanocytes are the cells in the skin that are responsible for the production of melanin, the pigment that determines the skin’s color.
