title: An amelanotic malignant melanoma of the lip: unusual shape and atypical location.
abstract: Amelanotic malignant melanoma (AMM) is characterized by little or no visible pigment. The diagnosis of AMM is a challenge for clinicians because it is a rare entity that presents with various clinical features. We describe a case of AMM on the lower lip in a 63-year-woman, which manifested as an erythematous mass that resembled grouped papules.
