Homozygous Factor V Leiden Thrombophilia in a Patient With Histologically Confirmed Thromboangiitis Obliterans

Factor V Leiden Mutation Causing Thrombophilia

It has autosomal dominant inheritance and is the most common cause of inherited thrombophilia. FVL is the most prevalent thrombotic risk factor known in the Caucasian population (around 5%). [1] Heterozygotes have a three to five times increased risk of thrombosis. Homozygotes are much less common but have a much higher thrombotic risk, around eight times increased risk. It leads to a hypercoag...

Thromboangiitis obliterans with cryoglobulinemia.

Thromboangiitis obliterans (TAO), or Buerger's disease, is a vascular occlusive disease associated with cigarette smoking. It typically affects medium sized vessels of extremities. Basic pathology of TAO is described to be endothelial activation with highly inflammatory intraluminal thrombosis preserving internal elastic membrane. Cryoglobulins are immunoglobulins that precipitate in the cold a...

Thromboangiitis obliterans.

Case presentation: A 39-year-old male smoker with a 2-year history of calf discomfort on ambulation culminating in left femoral-to-peroneal artery bypass presented with right leg discomfort and recurrent painful subcutaneous nodules on his feet and calves. Biopsy of a nodule from his right foot was interpreted as vasculitis with thrombosis and fibrinoid necrosis in subcutaneous vessels, and the...
