Rhabdoid cells in peritoneal fluid. A case report.
BACKGROUND
Rhabdoid tumor is an aggressive, malignant renal neoplasm of infants. Many extrarenal sites have been documented.


METHODS
A poorly differentiated carcinoma of the ovary with rhabdoid features occurred in a 36-year-old woman. The peritoneal fluid contained numerous malignant cells with rhabdoid features. Electron microscopy and immunocytochemistry corroborated the rhabdoid nature of the cells.


CONCLUSIONS
Rhabdoid cells can be distinguished from other neoplasms with similar cytologic features by ancillary studies and clinical history.
