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 % (+)).

To assess the use of anti-CD34 and anti-factor-XIIIa antibodies for the differential diagnosis of dermatofibroma (DF) and dermatofibrosarcoma protuberans (DFSP), we stained 40 DFs and 13 DFSPs. A significant population of dendritic and spindle cells was reactive with anti-factor-XIIIa in

Routine histology and immunohistochemistry can usually distinguish dermatofibroma (DF) and dermatofibrosarcoma protuberans (DFSP). DF generally expresses factor XIIIa whereas DFSP generally expresses CD34. The authors report 10 cutaneous fibrohistiocytic lesions combining clinical, histologic, and immunohistochemical features of both DF and
