ABSTRACT
A 56-year-old woman was referred to our hospital with symptoms of swelling, purpura, and pain in her limbs. Prior to referral, bleeding in her limbs had spontaneously appeared and disappeared several times. Prothrombin time (PT) and activated partial thromboplastin time (aPTT) were prolonged, and the factor II level was 17%. The plasma-mixing test indicated lupus anticoagulant (LA), which was confirmed using aPTT-LA and dilute Russell's viper venom time (dRVVT). Therefore, she was diagnosed with lupus anticoagulant-hypoprothrombinemia syndrome (LAHPS). During screening for underlying disorders, chest computed tomography (CT) revealed a retrosternal mass. Biopsy was not performed because the administration of freshly frozen plasma failed to correct her coagulopathy. Prednisolone (PSL) treatment (1 mg/kg) was initiated, which normalized the coagulation tests. The retrosternal mass also disappeared. PSL was tapered without LAHPS recurrence; however, the follow-up CT revealed systemic lymphadenopathy. Follicular lymphoma was diagnosed using lymph-node biopsy. Considering the subsequent LAHPS recurrence, six cycles of bendamustine + rituximab were administered. Complete response with no LAHPS recurrence was observed at the time of drafting this report. LAHPS is rare and distinct from antiphospholipid syndrome because it can cause severe bleeding. Underlying disorders should be evaluated in cases of LAHPS.
