Multiparameter flow cytometry in the diagnosis of a gynaecologic double tumor: a case report.

PURPOSE: An uncommon clinical presentation of metastatic tumor will often lead to additional diagnostic examinations. The patient of the present study was known to have endometrial cancer which was thought to be limited to the endometrium. Three months postoperatively, she developed ascites due to spread of the tumor, which is rarely seen in low-stage endometrial cancer.

METHOD: Multiparameter flow cytometry using both cell phenotype information and DNA ploidy was performed.

RESULTS

Retrospectively, the patient was diagnosed as having a DNA-diploid epithelial tumor of the endometrium as well as a DNA-aneuploid epithelial tumor in the left fallopian tube. It was shown that 3 months after primary surgery she developed ascites caused by metastatic tumor from the primary fallopian tube cancer.

CONCLUSION

The complete diagnosis was made using multiparameter flow cytometry which, at present, is not routinely applied in gynecologic pathology.
