Lentigo maligna is the precursor of a subtype of melanoma known as lentigo maligna melanoma, which is a cancerous (malignant) development of the cells that give our skin cells their color. Lentigo maligna is the most common kind of melanoma in the United States. In a similar vein, you could wonder how dangerous lentigo maligna is.

What is lentigo maligna (lentigo)?
The condition known as Hutchinson melanotic freckle is also known as Lentigo maligna. It is commonly referred to as ″in situ″ melanoma because the malignant cells are restricted to the tissue of origin, the epidermis, in where they first appeared, rather than spreading.
How common is lentigo maligna melanoma in NZ?
- 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.
- 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).
How fast does lentigo maligna grow?
In fair skinned adults over the age of 60, lentigo maligna is most typically found in sun damaged regions such as the face and neck, notably the nose and cheek, and in the hands and feet. Lentigo maligna is a chronic, slow-growing illness that might take years to fully manifest. In diameter, it expands slowly over a period of 5 to 20 years, or even longer 2).
How serious is lentigo maligna?
- 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.
- 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.
- 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).
Is lentigo maligna melanoma aggressive?
However, lentigo maligna melanoma can spread quickly despite the fact that it develops slowly and is typically non-cancerous. It is critical to recognize the signs and symptoms of lentigo maligna melanoma so that you can get treatment as soon as possible.
Is lentigo maligna a type of melanoma?
Overview. Lentigo maligna is a subtype of melanoma in situ that is characterized by an atypical proliferation of melanocytes within the basal epidermis; lentigo maligna that invades the dermis is referred to as lentigo maligna melanoma. Lentigo maligna melanoma is a type of melanoma that is characterized by an atypical proliferation of melanocytes
How long does lentigo maligna melanoma take?
In reality, according to a research published in the journal Melanoma Research in 2020, it takes an average of 28.3 years for a precancerous lesion (known as lentigo maligna) to progress to a cancerous lentigo maligna melanoma.
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.
Can lentigo maligna melanoma spread?
Lentigo maligna melanoma is an aggressive kind of skin cancer that can be treated if detected and treated by a doctor or dermatologist in a timely manner. As a result, anyone experiencing any early signs or symptoms should take them seriously and seek medical attention. The cancer is still in its early stages, known as lentigo maligna, and has not spread.
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.
What causes lentigo maligna?
The use of solariums or prolonged exposure to the sun are the primary causes of lentigo maligna. Chronic sun exposure/solar-induced skin damage are two factors that increase a person’s risk of acquiring lentigo maligna or a related disorder.
