Thrombotic vasculopathy associated with cryofibrinogenemia.

E Beightler1, D G Diven, R L Sanchez

  • 1Department of Dermatology, University of Texas Medical Branch, Galveston 77550.

Journal of the American Academy of Dermatology

Summary

Essential cryofibrinogenemia, a rare condition causing cold-precipitable proteins, can lead to severe complications. This case highlights its association with hemorrhagic necrosis and dermal thrombosis, even without inflammation.

Area of Science:

  • Hematology
  • Pathology

Background:

  • Cryofibrinogenemia involves cold-precipitable plasma proteins linked to various disorders like malignancy and thrombohemorrhagic conditions.
  • Essential or primary cryofibrinogenemia is infrequently reported in medical literature.

Observation:

  • A 48-year-old male presented with essential cryofibrinogenemia.
  • The patient exhibited hemorrhagic necrosis affecting the ears and extremities.
  • Histopathology revealed extensive eosinophilic thrombi within dermal vasculature, characterized by minimal inflammation and absence of vasculitis.

Findings:

  • The case demonstrates essential cryofibrinogenemia presenting with severe peripheral ischemic complications.
  • Histological findings indicate thrombosis as the primary pathological mechanism, distinct from inflammatory vasculitis.

Implications:

  • Cryofibrinogenemia should be considered in diagnosing patients with unexplained cold intolerance and dermal thrombosis.
  • This condition warrants further investigation, especially when presenting with minimal or no signs of inflammation.
