ABSTRACT
ABSTRACT: Epithelioid hemangioma (EH) is a benign vascular tumor displaying diverse histomorphologies. Among these, one EH subtype comprises cellular sheets of atypical epithelioid cells, posing potential challenges in distinguishing it from malignant vascular lesions. In this case report, we present a cutaneous cellular EH that carries the rare GATA6::FOXO1 gene fusion, a recent discovery. Our aim is to provide an updated insight into the evolving knowledge of EHs while delving into the histologic and molecular characteristics of the primary differential diagnoses.
