Pediatri c nodal marginal zone lymph oma in a Japanese boy

摘要

A 13-year-old boy with no remarkable past history presented with a 6 month history of right inguinal lymphadenopathy and a 1 month history of left cervical lymphadenopathy. Physical examination indicated no splenomegaly. Complete blood count was as follows: white blood cell count, 7.0 9 10 9 /L with normal differential; hemoglobin, 14.1 g/dL; and platelet count, 225 9 10 9 /L. Lactate dehydrogenase was 211 U/L, and other components of the comprehensive meta-bolic panel were also normal. On 18 F-uorodeoxyglucose positron emission tomography, uptake was seen in left cervi-cal, right inguinal, and right external iliac lymph nodes (LN; Fig. 1a). There was no evidence of bone marrow inltration.
