Factor XIII deficiency is a rare autosomal recessive congenital deficiency. Factor XIII plays an important role in the cross-linking of polymerized fibrin. Patients present with bleeding and delayed wound healing usually first noted at the umbilical stump or after circumcision. They have normal PT and aPTT tests but increased clot solubility.

Fibrinogen deficiency prolongs both PT and PTT , but only when the concentration is < 100 mg/dL. Other potential causes for your patient’s hematoma, independent of her PTT, include bleeding from the surgical site, a localized anatomical abnormality, diminished vascular integrity, thrombocytopenia, an acquired platelet function disorder, or factor XIII deficiency, listed in the order of decreasing prevalence. I’ve invited wo physician Factor XII deficiency is rarely associated with any symptoms (asymptomatic).
