title: Small noncleaved cell lymphoma in an adolescent with the XYY syndrome.
abstract: A 19-year-old male was diagnosed with stage III abdominal small noncleaved cell (SNCC) non-Hodgkin lymphoma (NHL). Cytogenetic evaluation of the tumor revealed a complex karyotype which included the t(8;14)(q24;q32), classically associated with this lymphoma histotype, and an extra Y chromosome. After remission was obtained, cytogenetic analysis of bone marrow cells and PHA-stimulated peripheral blood lymphocytes disclosed a normal karyotype except for the persistence of an extra Y chromosome, diagnostic of the XYY syndrome. This is the first reported case of SNCC NHL in an adolescent with the XYY syndrome.
