Hypervascular Palatal Benign Fibrous Histiocytoma Mimicking Hemangioma: Role of Combined Endovascular and Direct Puncture Embolization

Hypervascular tumors of the palate are rare and may radiologically mimic hemangiomas, posing significant surgical challenges due to the risk of excessive bleeding. We report a case of a 55-year-old female with a progressively enlarging palatal mass demonstrating intense enhancement on imaging and prominent tumoral blush on angiography. Transarterial embolization using polyvinyl alcohol particles achieved partial devascularization, followed by direct puncture embolization with N-butyl cyanoacrylate, resulting in complete angiographic devascularization. Surgical excision was performed with negligible blood loss. Histopathology confirmed benign fibrous histiocytoma. This case highlights the effectiveness of a combined embolization strategy in managing hypervascular palatal tumors safely.
