100 Assays Factor XIIIa was seen in 29 (97%) of 30 DFs (mean factor-XIIIa score, 4.1 +/- 0.3). In contrast, 18 (75%) of 24 DFSPs stained for factor XIIIa (mean factor-XIIIa score, 1.3 +/- 0.2), but in most of these cases the factor-XIIIa-positive cells were felt to be entrapped nonneoplastic dermal dendrocytes. Factor Xiiia staining Four of 10 (40%) compound nevi, 9 of 20 (45%) radial growth-phase melanomas, and 12 of 20 (60%) vertical growth-phase melanomas showed an increase in factor Xllla staining of DDCs (Ta-ble 1). The majority of cases, with the exception of 3 vertical growth-phase melanomas, had only slight (1-I-) increased staining (Fig.

Immunohistochemical analysis showed that factor XIIIa-positive histiocytic cells were distributed in the area without haemosiderin, but such cells were absent in the area with its deposition.

Factor XIII or fibrin stabilizing factor is a zymogen found from the blood of humans and some other animals.

Numerous large, stellate cells in placental villi, decidua, and chorionic membranes also expressed factor XIIIa at 7–9 weeks gestational age, before the onset of fetal hematopoiesis. AFX showed sparse populations of FXIIIa+ cells in the stroma (mean score = 1.33 or 10-25% positive), which were distinct from the atypical giant cells characteristic of these tumors. Keloid similarly contained trapped FXIIIa+ cells (mean score = 0.44 or < 5% positive) that were distinct from the spindle-shaped fibroblasts of the tumor mass. The 'satellite fibroblasts' were factor XIIIa-positive similarly to dendrocytes and perineurial cells. Our study reveals the lack of specificity of CD68 antibody to identify macrophages. It also presents granular cell tumor of the skin as an exception in the group of schwannomas by the presence of factor XIIIa-positive cells inside the neoplasm.

DF stains positively for Factor XIIIa and negative for CD34, while DFSP stains oppositely with positive CD34 staining and negative Factor XIIIa staining. This differentiation is, however, not absolute, as there are reports of Factor XIIIa positive DFSPs and of CD34 positive DFs.

Factor XIIIa is a pan-histiocytic marker, similar to CD68.

They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Our results revealed that the dermis of patch- and plaque-stage KS lesions contains an increased number of factor XIIIa-positive dermal dendrocytes compared with normal dermis and that some of these cells are spindle shaped. Many of the spindle cells in patch- and plaque-stage lesions of KS, however, are negative for factor XIIIa.
