Chordoma : Cytology

Comments:
Chordoma - Cytology: Smears typically show tumor cells, singly and in clusters, surrounded by copious amounts of metachromatic watery myxoid matrix with a fibrillar appearance as shown here. The cells are large and have multivacuolated cytoplasm (physaliphorous cells). Signet ring cell forms may be present. The nuclei are large but bland.
