Amelanotic lentigo maligna melanoma: A unique case presentation

Amelanotic melanomas comprise only 2% of melanomas and are commonly a diffi cult clinical diagnosis, due to the lack of melanin pigment typically found in melanomas. Even rarer is the amelanotic lentigo maligna, which may have an unusual clinical presentation, such as erythema, pruritus, or edema. Bi opsy is the key to diagnosis. Multiple therapies for amelanotic lentigo mal ignas have been tried, but excision, with margin control (Mohs micrographic surgery-frozen or paraffin sections), remains the treatment of choice.
