ABSTRACT
EWSR1::CREM gene fusions are increasingly being recognized in a diverse number of soft tissue tumors, including well-defined entities such as angiomatoid fibrous histiocytoma or clear cell sarcoma, and other unclassifiable tumors. As a group, EWSR1::CREM fused tumors often demonstrate primitive spindle or epithelioid cells, myxoid stroma, and a broad immunophenotype. Herein we present an unusual case of a child diagnosed with an intranasal malignant myxoid tumor harboring an EWSR1::CREM gene fusion. To the best of our knowledge, this is the first case of intranasal myxoid tumor with this particular fusion. Diagnosis and management of the case is discussed.
