Abstract

Hyperviscosity syndrome and cryoblobulinemia associated with lymphoproliferative disorder is a rare but life threatening condition. The delay of diagnosis can lead to severe mutilation and multiple organ damage. The plasma exchange therapy and the targeted treatment of the underlying disorder can lead to significant improvement. We present a patient who developed extensive soft tissue necroses, mimicking the peripheral artery disease. Despite surgical treatment, the skin lesions progressed involving fingers, earlobes and scrotum. Finally, the patient was diagnosed with multiple myeloma and hyperviscosity syndrome. The clinical condition improved after plasma exchange and myeloma treatment with thalidomide and dexamethasone.

Key words: multiple myeloma, hyperviscosity, skin necrosis
