Rheumatoid vasculitis (RV) is an infrequent complication of longstanding severe rheumatoid arthritis (RA). The active vasculitis associated with rheumatoid disease occurs in about 1%-5% of the patient population. RV is a manifestation of "extra-articular" rheumatoid arthritis and involves the small- and medium-sized arteries in the body. Newer RA treatments, including biologic therapies, offer a broader array of potential therapeutic options, although no controlled trials exist to guide treatment. In general, following tissue confirmation of the diagnosis, the severity of organ involvement and disease manifestations can guide treatment decisions. We want to alert clinicians of this unique yet severe complication of RA which has high morbidity and mortality. We describe a thought-provoking case of a 44-year-old male with past medical history (PMH) of hypertension who presented with over three-month history of lower extremity (LE) swelling, discoloration, and ulceration. Arthralgias with constitutional symptoms (fatigue, weight loss), large pericardial effusion, was found to have leukocytoclastic vasculitis along with rheumatoid factor (RF) >650, and anti-cyclic citrullinated peptide (anti-CCP) antibodies >300, low C4 and normal C3. Pericardial fluid appeared serous, exudative, showed histiocytes, multinucleated giant cells and necrotic debris consistent with rheumatoid effusion. Skin, right shin, punch biopsy showed epidermal necrosis from underlying occlusive vasculopathy. Skin, left lower back, punch biopsy showed focal leukocytoclastic vasculitis. The patient was started on high dose steroids with marked improvement in the symptoms, Rituximab was planned awaiting QuantiFERON to be negative. Pan-CT angiography of the whole body was negative for any vascular changes ruling out polyarteritis nodosa (PAN).
