Cytology of cervical chordoma in cerebrospinal fluid from a child: A case report

The cytologic findings on cerebrospinal fluid examination of cervical chordoma in a 2-year-old girl are presented. The major cell type was a small, isolated, hyperchromatic cell with sharply defined nuclear membrane and granular cytoplasm. However, the characteristic cell of this neoplasm, the so-called physaliferous cell with typical bubbly cytoplasm, was also noted. Cytologic findings were compared to biopsy findings, with a good correlation of tumor morphology. Clinical follow-up revealed unusually aggressive tumor behavior, and the patient died a year later despite intensive chemotherapy. The differential diagnosis of the condition is also discussed.
