As a result, the conditions most frequently manifested as Raynaud's phenomenon, distal gangrene, ischemic ulcers, purpura, livedo reticularis, headache, retinal hemorrhages, and encephalopathy. Nonspecific systemic and musculoskeletal symptoms, such as cutaneous vasculitis and neuropathy, can also be seen in patients with mixed cryoglobulinemia.
Livedo racemosa and livedo reticularis are the most common manifestations in skin, although other symptoms such as digital necrosis, subcutaneous nodules, and non-specific rash have been seen. The most common neurological manifestations of DADA2 are secondary to vasculitis.
