In a retrospective study of 125 primary cutaneous malignant melanomas of the foot treated from 1949 to 1977 the prognostic importance of various histological and clinical factors was observed. Clinical stage, location of tumour on the foot, level of invasion, tumour thickness, mitotic rate, and presence of ulceration correlated well with survival, while sex and histological type did not. A histological transition was found between the superficial spreading type and the acral lentiginous type, indicating a close biological relationship between the two types of melanoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
