Cytology of body fluids from different sites: an approach for early diagnosis of malignancy.

ABSTRACT

Malignant effusions are a common presenting sign of malignancy and reflect dissemination. A retrospective study of all fluid samples accessioned at the Department of Pathology, TUTH from April 2000 to October 2002 were done. Over the study period, a total of 584 specimens were examined- 324 peritoneal fluid, 224 pleural fluid, 19 pericardial fluid, 9 knee joint effusion and 8 Cerebro-Spinal Fluid (CSF). One hundred and nine (18.66%) out of 584 cases were found to have malignancy, 57 were male and 52 were female. The age group of the adult male ranged from 42-78 years and female ranged from 43-62 years. Three patients were children with age ranging from 8-11 years. Adenocarcinoma was the commonest that comprised 89%, followed by Non Hodgkin's lymphoma 6.5% squamous cell carcinoma 2.7% and small cell carcinoma comprised 1.8 %. Exfoliative cytology is cheap, rapid and highly effective tool for the evaluation of body fluid and should be advised in all effusion cases.
