Dermal Nerve Sheath Myxomas Harbor Recurrent DPYSL2::CDX1 Fusions and Expand the Spectrum of CDX1-Rearranged Soft Tissue Tumors.
Dermal nerve sheath myxoma (DNSM) is a rare benign mesenchymal tumor with presumed nerve sheath differentiation with distinctive morphologic and immunophenotypic features; however, its molecular pathogenesis remains poorly understood. We investigated a series of nine morphologically classic DNSMs and performed molecula...
