Scar 13 days after excision of coloured patch about 10mm square with 5mm margins from 1cm to right of base of nose. Length of incision required for skin flap to cover excision site. Scar should lighten and become finer for up to further 6 months if protected from sun. The best treatment of lentigo maligna is not clear as it has not been well ...
Monthly self-performed skin examinations and early referral to a dermatologist for monitoring are recommended interventions. Treatment approaches such as removal of the largest dysplastic nevus or all of the dysplastic nevi have not been shown to appreciably reduce the risk of developing melanoma and are not cost-effective; therefore, these ...

Various differential diagnoses of pigmented skin lesions, including dysplastic nevus, showing the relative incidence of biopsied lesions, and malignancy potential. When an atypical mole has been identified, a skin biopsy takes place in order to best diagnose it. Local anesthetic is used to numb the area, then the mole is biopsied.
It is difficult to distinguish these lesions with the naked eye alone, and even with some difficulty using dermatoscopy. As the lentigo maligna is often very large, it often merges with, or encompasses other skin tumors – such as lentigines, melanocytic nevi, and seborrheic keratosis. The second difficulty is the biopsy technique.
Surgical excision with a large safety margin is the main treatment for localized amelanotic melanoma. The suggested margin size for amelanotic melanoma is debatable since it varies according to the lesion's development, thickness, and invasion depth. [ 34 ]
Correlation of common lesion characteristics is made. Lesions that deviate from the common characteristics are labeled an "ugly duckling", and a further professional exam is required. The "Little Red Riding Hood" sign [74] suggests that individuals with fair skin and light-colored hair might have difficult-to-diagnose amelanotic melanomas ...
Skin biopsy is a biopsy technique in which a skin lesion is removed to be sent to a pathologist to render a microscopic diagnosis. It is usually done under local anesthetic in a physician's office, and results are often available in 4 to 10 days. It is commonly performed by dermatologists. Skin biopsies are also done by family physicians ...
