Superficial Thromboflebitis

  • Etiologia
    • Number 1 cause = venous insufficiency
    • Hypercoaguable state should be considered
      • “Trousseau syndrome”
        • Rarely associated with malignancy
        • If so: pancreas, stomach, lung, prostate, colon, ovary, bladder
    • Behcet’s syndrome
  • Clinical presentation
    • Erythematous, tender, subcutaneous nodules
    • Linear and can be cord-like
    • “migratory”
  • Histologia
    • Affects large VEINS
    • Initially neutrophilic, later mixed
    • Luminal thromboses
    • Strikingly only affect the vessel, not surrounding septa
  • DDx is Polyarteritis Nodosa
    • More inflammation, not thrombotic
    • Fibrinoid necrosis of tunica intima of ARTERIES
    • Can use elastic stain in difficult cases (there is no elastin in the wall of veins)
