Area of Science:

  • Dermatology
  • Rheumatology
  • Hematology

Background:

  • Necrobiotic xanthogranuloma (NXG) is a rare xanthomatous disease.
  • Scleroderma is a chronic autoimmune disease affecting connective tissue.
  • Cryoglobulinemia and cryofibrinogenemia are conditions involving abnormal proteins in the blood.

Purpose of the Study:

  • To report a unique case of NXG with concurrent scleroderma.
  • To investigate the association of cryoglobulins and cryofibrinogen in this context.
  • To explore the pathogenesis of autoamputation in this rare disorder.

Main Methods:

  • Case report of a 68-year-old male patient.
  • Clinical presentation and laboratory findings documented.
  • Literature review on NXG and related conditions.

Main Results:

  • Patient presented with NXG, scleroderma, cryoglobulins, and cryofibrinogen.
  • Autoamputation of distal digits and ear parts occurred with cold exposure.
  • The constellation of symptoms suggests a complex interplay of factors.

Conclusions:

  • This case demonstrates an unusual presentation of NXG.
  • The presence of cryoproteins may contribute to vascular complications.
  • Further research is needed to elucidate the pathogenesis of this rare condition.
