MEIS1-NCOA2-associated renal sarcoma

Thursday 6 September 2018

Some renal sarcomas are characterized by a MEIS1-NCOA2 gene fusion.

These neoplasms did not have a distinctive immunohistochemical profile, though both labeled for TLE1.

The morphologic features are distinct from other sarcomas associated with NCOA2 gene fusions, including mesenchymal chondrosarcoma, congenital/infantile spindle cell rhabdomyosarcoma, and soft tissue angiofibroma.

The aggressive histologic features of these neoplasms indicate malignant potential, thus warranting classification as a novel subtype of sarcoma.
