Melanoma is the most aggressive form of skin cancer affecting patients worldwide and has the potential to metastasize to virtually any organ in the body. Early detection is of paramount importance to minimize patient morbidity and mortality. However, there has been increasing evidence highlighting that geographical and ethnic variations in the clinical presentation of melanoma do exist. Unlike the Western population, the major subtype of melanoma affecting the Asian population is in fact, acral lentiginous melanoma (ALM) and not superficial spreading melanoma (SSM).We hereby present a case of left hallux subungual melanoma with scalp metastasis. This case underscores the importance of the examination of acral skin and the nail apparatus for melanoma in Asians.
