Abstract:
Chronic skin ulcers require extensive, systemic differential diagnosis; thus, they are difficult to diagnose and treat. Transient or persistent hypercoagulable states are among the rare causes of skin ulcers. Here, we present the case of a 27-year-old woman patient with recurrent, nonhealing skin ulcers of 8 years' duration, who had been treated unsuccessfully with various medications under different diagnoses at different clinics. On admission, a skin biopsy demonstrated occlusive vasculopathy, and the search for an inherited hypercoagulable state revealed a heterozygous factor V Leiden mutation. The patient was treated with anticoagulants and hyperbaric oxygen. On treatment, the skin lesions healed and did not recur.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
