Multiple polypoid projections of granulation tissue developed in two patients receiving isotretinoin for acne. Histological study of the lesions revealed increased amounts of non-sulphated acid mucopolysaccharides in the ground substance of the granulation tissue stroma. Complete resolution occurred following curettage with or without chemical cautery. The role of isotretinoin in the development of these lesions is discussed.
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.
