Untitled Upon admission, her vital signs were stable. Examinations of head, ears, eyes, nose, throat, heart, and lung were normal. There was bilateral edema, cyanosis, and severe tenderness of distal extremities, without synovitis. There was diffuse superficial, livedo-like purpura on her thighs, frank necrosis of the tips of all her toes and 4 fingers, but no ulcerative lesions (Figures 1A, 1B ). Her upper arms, thighs, and trunk were spared from lesions or pain.

Our patient presented with acute necrosis of 14 digits, resulting in total or partial autoamputation. She had no known vasculitic internal organ involvement or background of Sjögren’s syndrome or antiphospholipid antibody syndrome. Serologic screening of asymptomatic patients with SSc has shown a low frequency of ANCA-positivity (10%–13%)
mpo89buzz mpo89 Resources and Information Three months before admission, she developed muscle and joint pain in her distal extremities, with temporary relief taking oral and intravenous methylprednisolone. However, the purple discoloration and painful swelling of her toes progressed, and was unresponsive to lidocaine sympathectomies. Subsequently, she developed leg edema and rash, with numbness, tingling, and blistering. Three days before admission, the tips of her fingers and toes turned black.

. Since patients with limited SSc of long duration have much lower risk of renal crisis than patients with early diffuse SSc, weighing the risk to her of digital loss versus renal crisis, our patient was started on therapy of high-dose corticosteroids, cytotoxic therapy, and other treatments within 2 weeks of her fulminant digital infarction. She demonstrated good clinical response to therapy without steroid-induced renal impairment or visceral organ involvement other than her digits.
Because ANCA-positivity in asymptomatic patients with SSc does not consistently correlate with clinical characteristics, we do not recommend routine ANCA screening. However, our experience suggests that when SSc patients present with multiple necrotic digits, vasculitis should be considered. ANCA tests and appropriate biopsies may identify SSc-AAV. Early therapeutic intervention may improve prognosis, especially in life- or organ-threatening conditions.

Antineutrophil Cytoplasmic Antibodypositive Digital Necrosis in a After admission, treatment with intravenous (IV) heparin, narcotics, and methylprednisolone at 1 g daily for 3 days was started. IV cyclophosphamide (1 g) was given. IV epoprostenol was titrated up to 8 ng/kg/min for 6 days. Oral vasodilators included sildenafil 20 mg tid and nifedipine 10 mg tid. Vascular surgery consultation advised against any surgical intervention.
Antineutrophil cytoplasmic antibody (ANCA) positivity in the setting of asymptomatic systemic sclerosis (SSc) does not consistently correlate with clinical characteristics. We describe a 31-year-old Latina woman with a 10-year history of limited SSc [sclerodactyly, tight facial skin, antinuclear antibody (ANA)-positive, gastroesophageal reflux disease, Raynaud’s phenomenon with no previous digital ulcerations, and without sicca-related symptoms or pulmonary or cardiovascular disease], who presented with severe digital necrosis. Her SSc had been stable under therapy with lansoprazole, hydroxychloroquine, celecoxib, and nifedipine.
. A case series of 50 patients with SSc-AAV suggests that SSc patients with both ANCA and Scl-70 antibodies are at an even higher risk of developing life-threatening AAV, but is inconclusive for SSc disease period and type

Bilateral lower extremity computed tomography (CT) angiogram with runoff failed to reveal inflammatory vasculitis, but vessels distal to the dorsalis pedis could not be visualized. A high resolution chest CT scan showed increased reticulations in the left lung with septal thickening, suggestive of early subpleural honeycombing. Pulmonary function testing demonstrated forced vital capacity 88% of predicted and DLCO 21% of predicted. There was no evidence of pulmonary hypertension by echocardiogram. Skin (punch) biopsy of the right shin showed small-vessel vasculitis with fibrinoid necrosis in the vessel wall, leukocytoclasia, and eosinophilia (Figure 2 ).
Skin biopsy of the right shin: fibrinoid necrosis can be seen around the blood vessel wall (thin white arrow); an infiltrate of neutrophils, neutrophilic debris, and scattered eosinophils can also be seen (thick white arrow).

After discharge, she received 40 hyperbaric oxygen treatments for her gangrenous digits, IV cyclophosphamide 1 g monthly for 6 months, and oral sildenafil 20 mg tid. Mycophenolate mofetil was then substituted and titrated to 2.5 g orally daily. Over 24 months, all of the 14 necrotizing digits underwent autoamputation. She resumed full-time work as an accountant. Her p-ANCA test remains positive with high anti-MPO titers (76–130 U/ml).
