1. The key for the case is carcinoma or sarcoma. 2. Notice that all stained epithelial markers (pan CK, EMA, CK7, CK19, CK-low, 34BE12, ck5/6) are negative. If enough sampling was enough, mostly it is not a carcinoma. 3. Then it is a sarcoma case. Next question is what type of sarcoma. 4. Calponin and actin are weakly positive (desmin negative). If they are true, it can be poorly differentiated leiomyosarcoma. What is AACT? 5. Do caldesmon stain 6. If smooth muscle origin cannot be determined, 多形性未分化肉类/恶性纤维组织细胞瘤is reasonal call.
