AIM To combine ultrasound-guided fine-needle aspiration (US-FNA) and Liu (Riu) stain to make a quick study on liver tumor lesions. METHODS Two hundred and twenty-eight aspirations from 232 patients were completely studied. The operator himself made the quick cytodiagnosis of US-FNA smear stained by Liu method within thirty minutes. The US-FNA specimen was also sent to the pathological departm...

AIMS To assess the efficacy of cytodiagnosis in necropsy practice. METHODS Fifty three focal lesions from 46 necropsies were assessed by direct smears taken from the lesions. The smears were air-dried and stained by a modified Giemsa technique, with two cases having supplementary histochemistry. All of the slides were assessed independently before review of the necropsy histology. RESULTS O...

A 93-year-old female was transferred to the emergency ward of our hospital due to disturbance of consciousness and hypotension. Computed tomography showed bilateral pleural and pericardial effusion without evidence of tumor masses or lymphadenopathy. Cytodiagnosis of pleural effusion revealed proliferation of atypical lymphoid-like cells with pan-B surface markers. We suspected primary effusion...

The cytodiagnostic acridine orange (AO) fluorescence microscope method was applied to exfoliated material from 4348 cases. The method utilizes increased amounts of cytoplasmic ribonucleic acid (RNA) in malignant cells to demonstrate them in brilliant orange and red fluorescence colors. Scanning smears under low magnification readily revealed the presence of cells with increased fluorescence. Us...

A sputum test is noninvasive and simple. It contributed to correct diagnosis of a patient with severe acute respiratory failure. We again point out the usefulness of sputum cytodiagnosis for differentiating severe pneumonia.
