13 Discussion What s kind of diagnostic plan and therapeutic plan? Labolatory, imaging, etc

14 Occam s razors, Hickam s dictum Occam s razor shall apply to a young under 50years old

15 VINDICATE Vascular less likely Infection IE, Tb, HIV Neoplasm malignant lymphoma Degenerative less likely Intoxication less likely Congenital less likely Auto-immune granulomatous disease vasculitis Trauma less likely Endocrinopathy less likely Iatrogenic Idiopathic Inheritance less likely Psychogenic less likely

16 Plan We checked Blood culture Chest & abdominal CT Biopsy A left axillary lymph node BAL gastric tissue

17 Labo2 HTLV-1 - HIV1/2 - IL-2R 2550 U/mL Ferritin 151 ng/ml ANA <40 MPO-ANCA - PR3-ANCA - C3 94 mg/dl C4 30 mg/dl IgG 1099 mg/dl IgA 404 mg/dl IgM 96 mg/dl

18 Chest CT CT of the chest shows multiple nodular lesion and consolidation. These lesion are along bronchus, and spread to pulmonary parenchyma without destroying lung components. There are many small mediastinal lymph nodes. lymph nodes

19 Abdominal CT Gastric wall thickness in the lesser curvature Splenomegaly, mass in the spleen Lymphadenopathies around the SMA and abdominal aorta.

20 pathology Lymph node Gastric tissue BAL Many atypical cells can be seen

21 CD 56 CD CD 43

22 Pathological diagnosis highly aggressive NK/T cell lymphoma

23 Pathological diagnosis highly aggressive NK/T cell lymphoma EBV assosiated

24 There are three reasons why we came up to the diagnosis of EBV associated lymphoma. 1. It was the early onset at the age of There were repeated history of high fever. 3. The disease was spread to many organs.

25 Serodiagnosis of Ebstein-Barr virus VCA-IgG (<0.5) VCA-IgM (<0.5) EA-IgG (<0.5) EBNA-IgG (<0.5) Not infected Acute infected + ± + - Post infected + ± ± + Chronic infected ++ ± +++ ± This case ++(10.9) -(0.2) +(1.5) +(1.5)

26 Ebstein-Barr virus infection chronic EBV infection CAEBV *Ebstein-Barr virus associated lymphadenopathy *It is resulted from EBV infected T/NK LPD *Fetal in 5-15 years if treated symptomatically due to lymphoma, organ failure, HPS, bleeding, etc.

27 Final diagnosis experience of hives after having insect bites and thronbocytopenia were signs of CAEBV

28 After chemothrapy, he received cord blood stem cell transplantation.
