Chondroid Chordoma: An Uncommon Bone Neoplasm

Abstract

Chordomas are rare, slowly growing, locally aggressive neoplasms of bone that arise from embryonic
remnants of the notochord. Chondroid-chordoma is an uncommon variant of chordoma. These tumors
typically occur in the axial skeleton. Here we report a rare occurrence of chondroid variant of chordoma
at sacrococcygeal region in a 60 year old female. Magnetic resonance imaging revealed expansile mass
involvingsacrococcygeal region.Gross and microscopic examination confirmed chondroid chordoma.Later
patient underwent radiotherapy, doingwell,on a one year follow up. Chondroid chordoma is discussed due
to its predilection for occurrence at sacrococcygealregion and its more favorable prognosis compared with
that of conventional chordoma.
