Figure 3. Cytomorphology from fine-needle aspiration of the liver specimen received with requisition stating a history of “jaundice and liver mass” without mention of disease elsewhere in the body. (A) Loosely cohesive population of overtly cytologically malignant cells with anisocytosis and varied morphologic features (Papanicolaou stain, 400×). (B) Some malignant cells with rounded-to-oval nuclei and open chromatin and others with spindled hyperchromatic nuclei (Papanicolaou stain, 600×). (C) Sarcomatoid cells with tapering cytoplasmic extensions, nuclear pleomorphism, and coarse chromatin readily identified (Papanicolaou stain, 600×).
