Figure 4. Histomorphology from liver core biopsy also received with requisition giving history of “jaundice and liver mass” without mention of disease elsewhere in body. (A) Geographic necrosis comprising much of the core biopsy with viable malignant cells at tips of cores (hematoxylin and eosin, 200×). (B) Pleomorphic malignant cells with predominantly spindled and focally epithelioid morphologies, nucleomegaly and hyperchromasia, compatible with a sarcomatoid morphology (hematoxylin and eosin, 400×).
