也可以從這些antigen 的功能來解題
CD31 is more specific for vascular endothelium, making it a preferred marker for confirming vascular origin in tumors (e.g., angiosarcomas).
CD31 通常是血管會有的 所以Kaposi sarcoma, angiosarcoma 會有陽性反應
CD34 has broader expression, being present in endothelial and stromal cells, and is commonly used to identify hematopoietic progenitors or soft tissue tumors.
CD34 可以記軟組織 所以 solitary fibrous tumor 會有陽性反應
