Lentigo maligna. Close-up of the nose of an 80 year-old woman with Lentigo maligna. Raised dark brown spots and patches are seen. Normal lentigo is common in the elderly and light-skinned people who have been exposed to a lot of sun. Flat and discoloured areas are seen similar to freckles. Lentigo maligna,however,is a sign of the pigmentation developing into a malignant melonoma,the most serious type of skin cancer. Malignant melanoma is a tumour of melanocytes,the cells that produce melanin (the pigment that colours the skin,hair and iris). Unless diagnosed and treated early,this tumour is highly malignant and can spread throughout the body | |
