What are the two approaches used in cytology for unknown masses?

The two approaches are: 1. Determine if the sample is sufficient for diagnosis. 2. Determine if there is evidence of inflammation or cystic content, or if it mainly consists of tissue cells indicating neoplasia. Signup and view all the answers

What are the cytological criteria of malignancy?

The cytological criteria of malignancy include cellular criteria (cells being in a place they do not belong), nuclear criteria (variation in shape or size, abnormal mitotic figures), and cytoplasmic criteria (basophilia/hyperchromasia, vacuolation, phagocytosis). Signup and view all the answers
