This puts people who have sun-affected epidermis and the ones who fork out a lot of their time outside at greater risk. Additional risk factors when it comes to the development of lentigo maligna include light/fair skin, genealogy or family history associated with skin cancer|cancer of the skin, being past 60 years of age, being male, and facing some history of pre-cancerous or noncancerous skin spots. Secondly: lentiginous melanoma would be the variant form of melanoma at slow progression which is observed in sun-harmed skin associated with the limbs and trunk. Lentiginous melanoma procures diagnosis as soon as the malignant cells come in situ. Moreover, it’s thought to represent a reduced chance of invasive melanoma. This particular melanoma only has very recently become classified as being distinct right from superficial melanoma spreading as well as lentigo maligna. Read further to learn more differences between lentiginous and lentigo and how these can be treated.

What is lentiginous?


So who acquires lentiginous melanoma? The possibility of lentiginous melanoma pertains to sun damage. Hence, lentiginous melanoma is much more common among outdoor working people, in the elderly as well as in connection to solar harm, including non-melanoma cancer of the skin.
