title: Childhood non-Hodgkin's lymphoma developing from recurrent neck mass.
abstract: Non-Hodgkin's lymphoma (NHL) in an 8-year-old boy developing from recurrent neck mass during 15-months history is presented. Two biopsies carried out during this period were interpreted as reactive change. The third biopsy was diagnosed as NHL. He died of the systemic disease 19 months after the first admission. Clinical, histological and immunocytochemical investigations for the three biopsy materials revealed that the first and the second biopsies were reactive, and the third biopsy was neoplastic, B cell lymphoma. Known etiological factors causing lymphoreticular disorders are reviewed by the literatures, and absence of these factors in the present case is described.
