To begin with, compared to ovarian carcinoma, malignant peritoneal mesothelioma has a higher expression of the nerve growth factor receptors p75 and p‐TrKA and the angiogenic molecules bFGF but lower expression of the laminin receptor 67‐kDa and α6 integrin, the angiogenic molecules VEGF and IL‐8, and the human leukocyte antigen G.21Moreover, the role of calretinin and thrombomodulin as positive markers and Ber‐EP4, MOC‐31, CA19‐9, and estrogen receptor as negative markers in differentiating malignant abdominal mesothelioma and ovarian carcinoma has been established in multiple studies.22, 23. The gene discussed is THBD; the disease is malignant peritoneal mesothelioma.
