Abstract Malignant vascular neoplasms of the liver are uncommon. We report the case of a young woman who developed an epithelioid hemangioendothelioma of the liver associated with multiple focal nodular hyperplasias and hepatic cavernous hemangiomas. Such an unusual association is probably not fortuitous and could support the theory that focal nodular hyperplasia is a reaction to an abnormal vascular supply rather than a true neoplasm.

Epithelioid hemangioendothelioma (EHE) is an uncommon low-grade malignant vascular tumor that may arise in soft tissue/bone or visceral sites such as the liver and lung. As this tumor exhibits epithelioid morphology, it frequently causes diagnostic confusion with other epithelioid vascular neoplasms as well as carcinoma. While 90% of classic EHE are driven by aWWTR1-CAMTA1fusion gene, a histologically distinctive subset of EHE has been recently shown to harbor a different fusion gene,YAP1-TFE3. This variant is likely underrecognized given its rarity and only recent description. Notably, EHE frequently involves the liver but only one case of hepaticYAP1-TFE3rearranged EHE has been reported to date. We present the second case ofYAP1-TFE3rearranged EHE affecting a 65-year-old woman and presenting as multiple liver masses, with characterization of the fusion gene at the transcriptomic and genomic levels. There are several educational points noted from this case.YAP1-TFE3rearranged EHE shows distinctly vasoformative foci, unlike classic EHE and mimicking angiosarcoma or epithelioid hemangioma. The tumors cells show a histiocytoid appearance with voluminous cytoplasm, similar to otherTFE3-rearranged tumors. Finally, in the liver, this tumor may in part mimic focal nodular hyperplasia of the liver which is an underrecognized diagnostic pitfall. This report highlights the key diagnostic and genetic features of this newly recognized variant of hepatic EHE to aid pathologists in appropriately classifying these tumors.
