[Cytologic and histopathologic examinations of fine-needle aspirates of pancreatic mass].
OBJECTIVE
To evaluate the usefulness in diagnosis of pancreatic mass by histopathologic and cytologic examinations of fine-needle aspirates obtained under ultrasonic guidance.


METHODS
In 83 patients with pancreatic mass, percutaneous fine-needle aspiration was performed under ultrasound guidance. The fluid aspirates were examined cytologically and tissue fragments examined histopathologically. The findings were compared.


RESULTS
The rate of accuracy, sensitivity, and specificity of cytologic examination was 98.8%, 98.3% and 100% respectively, and that of histopathologic diagnosis was 95.1%, 93.2% and 100%, respectively. There was no false positive.


CONCLUSIONS
Both histopathologic and cytologic examinations of fine-needle aspirates of pancreatic mass are sensitive and accurate enough for the diagnosis of pancreatic diseases. They can be used with complementarity.
