Amelanotic lentigo maligna melanoma: a unique case and review of the literature.
It has been estimated that 2 percent of all melanomas are clinically amelanotic, with amelanotic lentigo maligna melanoma being an even rarer presentation. These neoplasms have presented clinically as neurodermatitis, eczema, and erythema. Given the lack of clinical markers and subsequent delay in diagnosis of these lesions, they are potentially more dangerous than pigmented lentigo maligna melanomas. We report a case of an amelanotic lentigo maligna melanoma presenting as an ill-defined edematous area on the left cheek of an elderly woman.
