RESUMEN
We report a case of 74 year old man presented with generalized lymphadenopathy with hepatosplenomegaly. Lymph node biopsy revealed angioimmunoblastic lymphadenopathy with dysproteinemia (AILD) and most areas of lymph node were replaced with large atypical lymphocytes which were revealed to be T cells by immunohistochemistry. All together, the patient was diagnosed as AILD-like T cell lymphoma with bone marrow involvement. The patient presented monoclonal gammopathy (IgG lambda) without any evidence of plasma cell dyscrasia or secondary amyloidosis. After three cycles of combination chemotherapy including cyclophosphamide, prednisone, vincristine and doxorubicin, the patient achieved partial remission with decreased level of serum and urine monoclonal protein.
