Epithelioid Fibrous Histiocytoma With an ETV6::NTRK3 Fusion in a Child: A Case Expanding the Spectrum of Receptor-Tyrosine Kinase Driven Epithelioid Fibrous Histiocytoma
{{output}}
Epithelioid fibrous histiocytoma (EFH) is a benign cutaneous neoplasm that is now recognized to be largely driven by ALK rearrangements. Rare cases of EFH and EFH-spectrum tumors with other receptor tyrosine kinase (RTK) fusions including RET and NTRK3 have be... ...
