Epithelioid vascular tumours include benign epithelioid haemangioma (EH) and epithelioid angiomatous nodule, low-grade malignant epithelioid haemangioendothelioma and high-grade epithelioid angiosarcoma. These tumours share epithelioid cell morphologies and intracytoplasmic vacuoles, with distinction based on differing architectural and nuclear features. This report highlights a case of EH, angiolymphoid hyperplasia with eosinophilia subtype, involving the vermillion border of the lower lip in an elderly female patient. The clinical and histological features, differential diagnosis, aetiopathogenesis, molecular basis and treatment options are discussed as part of a comprehensive review of this rare entity.
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.
