Cutaneous findings are variable and nonspecific and usually affect the lower extremities

Palpable purpura or skin ulcers (45%) [1] ; ulcerations may resemble pyoderma gangrenosum

Petechiae, vesicles, pustules, hemorrhagic bullae, livedo reticularis, digital necrosis, subungual splinter hemorrhages, and genital ulcers resembling squamous cell carcinoma have been reported
