NSE-positive lymphoblastic lymphoma in a boy with cutaneous involvement, giant splenomegaly, and hyper-gamma globulinemia

We report a 6-year-old boy who was diagnosed as having neuron-specific enolase (NSE)-positive pro-T cell type lymphoblastic lymphoma preceded with a variety of symptoms such as skin rash, giant splenomegaly, and hyper-gamma globulinemia. He first showed cervical lymphadenopathy in June 1999, followe...

Summary:We report a 6-year-old boy who was diagnosed as having neuron-specific enolase (NSE)-positive pro-T cell type lymphoblastic lymphoma preceded with a variety of symptoms such as skin rash, giant splenomegaly, and hyper-gamma globulinemia. He first showed cervical lymphadenopathy in June 1999, followed by a fever of unknown origin with atypical erythema, hepatosplenomegaly, and a few lymphoblastoid cells present in the bone marrow in September. However, no specific treatments were started at this point because a cervical lymph node biopsy failed to show malignancy and the patient's signs and symptoms resolved spontaneously. Two months later, oral prednisolone therapy was started due to recurrence of the fever and erythema, but resulted in exacerbation of the skin lesions and generalized lymphadenopathy. A biopsy of the right inguinal lymph node performed in January 2000 revealed proliferation of lymphoblastic cells positive for CD3, CD5 and NSE with a rearrangement of T cell receptor gene Jdelta, leading to the diagnosis of lymphoblastic lymphoma. After intensified chemotherapy, he received an autologous peripheral blood stem cell transplantation and has been in complete remission for 4 years.
