General description

Factor XIIIa is a plasma transglutaminase that is part of the blood coagulation cascade and plays a critical role in stabilizing fibrin networks at the site of an injury to produce a clot. Factor XIIIa is expressed in platelets, megakaryocytes, fibroblast-like cells in the placenta, uterus, and prostate, monocytes and macrophages, and dermal dendritic cells. Anti-Factor XIIIa immunohistochemistry is used to identify fibrohistiocytic neoplasms such as dermatofibroma.

Factor XIIIa is a blood proenzyme that has been identified in platelets, megakaryocyte, and fibroblast-like mesenchymal or histiocytic cells present in the placenta, uterus, and prostate; it is also present in monocytes and macrophages and dermal dendritic cells. Anti- Factor XIIIa has been found to be useful in differentiating between dermatofibroma (90% (+)), dermatofibrosarcoma protuberans (25%(+)), and desmoplastic malignant melanoma (0%(+)). Factor XIIIa positivity is also seen in capillary hemagioblastoma (100%(+)), hemangioendothelioma (100%(+)), hemangiopericytoma (100%(+)), xanthogranuloma (100%(+)), xanthoma (100(+)), hepatocellular carcinoma (93%(+)), glomus tumor (80%(+)), and meningioma (80 % (+)).
