To investigate intelectin-1 expression in cancers that may be confused with MPM in histopathological analyses, we prepared tissue microarrays of several primary tumors: biphasic synovial sarcoma, breast cancer, colon adenocarcinoma, epithelioid angiosarcoma, epithelioid hemangioendothelioma, gastric adenocarcinoma, lung cancer, ovarian adenocarcinoma, renal cell carcinoma, and urothelial carcinoma. Here, ITLN1 is linked to lung carcinoma.
