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. It occurs in sun damaged skin so is generally found on the face or neck, particularly the nose and cheek Lentigo maligna stays on the outer surface of the skin. When it starts growing beneath the skin's surface, it becomes lentigo maligna melanoma. It's the least common type of melanoma Lentigo maligna is a specific type of melanoma in situ that occurs around hair follicles on the sun-damaged skin of the head and neck. Lentigo maligna melanoma is diagnosed when the melanoma cells have invaded into the dermis. It is the second most common form of melanoma Initially the lentigo maligna is a flat, brown, stain-like lesion. The development of an elevated nodule within the area of pigmentation indicates the change to vertically invasive lentigo maligna melanoma. This variant does not occur in children. Skin.

Lentigo maligna (LM), a form of in situ melanoma, 1-3 is characterized in its earliest stages by scattered single atypical melanocytes involving the dermoepidermal junction (Fig. 1a) and extending down skin appendageal structures. It usually occurs within severely sun‐damaged skin. 4 As the tumour progresses, melanocyte density and degree of cytological atypia increase (Fig. 1b) A lentigo (syn. lentigine), unlike a freckle (ephilis) maintains its pigmentation throughout the year. The increase in melanin is often associated with an increase of normal melanocytes at the dermal-epidermal junction. This chapter is set out as follows This book provides a comprehensive approach to the diagnosis and management of melanoma of the lentigo maligna subtype, specifically. Authors from multiple fields provide educational information along with importantly relevant, practical, and insightful details to improve the understanding an Lentigo maligna is a subtype of in situ melanoma appearing usually in chronically sun-exposed skin (mostly the face) of elderly patients.
