They were also observed associated with epithelial structures in lung and kidney, but were only rarely observed in liver, thyroid, testis and spleen. Factor XIIIa-positive dendrocytes are almost absent in the reticular dermis and markedly reduced in number and size in the adventitial dermis. By contrast, the densities of vimentin-positive cells and CD34-positive cells were unremarkable. The biologic significance of this finding is unknown.

By contrast, the densities of vimentin-positive cells and CD34-positive cells were unremarkable. The biologic significance of this finding is unknown. However, at least a subset of dermal Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of 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. Comparison of Angiomyofibroblastoma and Aggressive Angiomyxoma in Both Sexes: Four Cases Composed of Bimodal CD34 and Factor XIIIa Positive Dendritic Cell Subsets Author links open overlay panel Jeffrey S. Silverman 1 2 Jak Albukerk 1 2 Ali Tamsen 1 2 Factor XIIIA is the catalytic subunit and is a dimer of M.W. 160,000. According to studies, Factor XIII is present in plasma as an alpha2beta2 heterodimer (M.W. 320,000); whereas in platelets, only the alpha2 unit exists. Factor XIIIa is a dermal dendrocyte marker and shows variable reaction with these types of tumors (3,4).

Noun 1. factor XIII - in the clotting of blood thrombin catalyzes factor XIII into its active form Also, ECD lesions of a pulmonary origin are positive for factor XIIIa. Factor XIIIA deficiency was diagnosed by positive urea solubility test of fibrin clot and essentially no enzymatic activity of factor XIIIA (<1% of normal).

Factor XIIIA is the catalytic subunit and is a dimer of M.W. 160,000.

FXIIIa plays a key role in fibrin stabilization, and defective fibrin stabilization is demonstrable as a result of severe haemorrhagic manifestations of congenital FXIII deficiency, which is an autosomal recessive disorder. Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells. They are subsets of mesenchymal cells, cancer-associated macrophages and antigen-presenting cells. Factor XIIIa-positive dendrocytes present at the periphery and inside epithelial neoplasms are an heterogeneous group of cells.

A significant population of dendritic and spindle cells was reactive with anti-factor-XIIIa in 90% of DFs. In DFSP, most cases had very few or no reactive tostatin-positive cells are speci¢cally involved in the healing process of psoriasis. The reduction of the factor XIIIa-posi-tive cells was associated with the healing process as a whole, but showed no relation to either treatment.Key words: dendri-tic cells; epidermal thickness; immunohistochemistry; psoriasis.

The aim of the present study was to evaluate the contribution of factor XIIIa (FXIIIa)-positive dermal dendritic cells to formation of keloids and hypertrophic scars. The numbers of FXIIIa-positive cells were counted in the keloid, hypertrophic scar and mature scar, each of which was divided into fibrocollagenous area and superficial dermal area overlying the nodular lesion.

It is activated by thrombin to factor XIIIa. XIIIa is an enzyme of the blood coagulation system that crosslinks fibrin. Deficiency of XIII worsens clot stability and increases bleeding tendency. Immunohistochemical positive for Factor XIIIa. CD34 is usually negative in dermatofibroma but highlights the intermixed vessels and may be focally positive at the periphery of the lesion in the cellular variant (figure 17). Factor 13A usually stains the lesional cells (figure 18).

Factor XIIIA deficiency was diagnosed by positive urea solubility test of fibrin clot and essentially no enzymatic activity of factor XIIIA (<1% of normal).
