Figure 4

Comparison of CTC morphology with biopsy histology and touch preparation cytology in a patient with metastatic colorectal cancer. (a) Low-power histology of the liver metastasis from 1999 of Patient E (H & E, 20X). (b) High-power histology of the liver metastasis from 1999 of Patient E (H & E, 110X oil). (c) High-power cytology of retroperitoneal metastasis from 2002 of Patient E (H&E Stain, 100X oil). (d) High-power cytology of retroperitoneal metastasis from 2002 of Patient E (Wright-Giemsa stain, 100X oil). (e)–(g) CTCs identified in the blood of Patient E in 2008.
