Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a self-limiting lymphadenitis. It is a benign disease mainly characterized by high fever, lymph node swelling, and leukopenia. Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening disease with clinical symptoms similar to those of KFD, but it requires a significantly more aggressive treatment. A 19-year-old Korean male patient was hospitalized for fever and cervical lymphadenopathy. Variable-sized lymph node enlargements with slightly necrotic lesions were detected on computed tomography. Biopsy specimen from a cervical lymph node showed necrotizing lymphadenitis with HLH. Bone marrow aspiration showed hemophagocytic histiocytosis. The clinical symptoms and the results of the laboratory test and bone marrow aspiration met the diagnostic criteria for HLH. The patient was diagnosed with macrophage activation syndrome—HLH, a secondary HLH associated with KFD. He was treated with dexamethasone (10 mg/m2/day) without immunosuppressive therapy or etoposide-based chemotherapy. The fever disappeared within a day, and other symptoms such as lymphadenopathy, ascites, and pleural effusion improved. Dexamethasone was reduced from day 2 of hospitalization and was tapered over 8 weeks. The patient was discharged on day 6 with continuation of dexamethasone. The patient had no recurrence at the 18-month follow-up.

Abstract PDF

We report the case of a 16-month-old patient with chronic immune thrombocytopenia (ITP) patient who experienced delayed treatment-free response (TFR) after romiplostim treatment. He received intravenous immunoglobulin every month to maintain a platelet count above 20,000/μL for 2 years. Thereafter, he received rituximab and cyclosporine as second-line therapy, with no response, followed by romiplostim. After 4 weeks of treatment, the platelet count was maintained above 50,000/μL. Following 7 months of treatment, he discontinued romiplostim, and the platelet count decreased. His platelet counts remained above 50,000/μL, without any bleeding symptoms, 2 years after romiplostim discontinuation. This is the first report of TFR after romiplostim treatment in pediatric chronic ITP.
