What is the difference between lentigo maligna and lentigo maligna melanoma?

Lentigo maligna is an early form of melanoma in which the malignant cells are confined to the tissue of origin, the epidermis, hence it is often reported as ‘in situ’ melanoma. Lentigo maligna melanoma is diagnosed when the malignant melanoma cells have invaded into the dermis and deeper layers of skin.Click to see full answer. Besides, is lentigo maligna cancerous?Lentigo maligna melanoma is a type of invasive skin cancer. It develops from lentigo maligna, which is sometimes called Hutchinson’s melanotic freckle.One may also ask, what does lentigo look like? Lentigo: A type of freckle that is a small tan, brown, or black spot which tends to be darker than the usual (ephelis-type) freckle and which do not fade in the winter. This kind of spot is referred to as lentigo simplex. A lentigo looks like a lentil bean. The plural is lentigines. Similarly one may ask, is lentigo maligna curable? Lentigo maligna can be cured with surgery. However, if the whole area is not removed completely with the appropriate surgery, some may develop into an invasive melanoma. It is therefore important to have it removed with a rim of normal skin (an adequate surgical margin).Does lentigo maligna come back?Yes, the outlook for lentigo maligna and melanoma in situ is excellent. It is very rare for them to come back because they were ‘in situ’, therefore they will not have had an opportunity to spread elsewhere in the body.
