Precursor T-cell acute lymphoblastic leukemia/lymphoma commonly affects adolescents, and is associated with mediastinal mass in over half of the cases, with early dissemination to bone marrow, gonads and the central nervous system. We present a rare case of precursor T-cell acute lymphoblastic leukemia/lymphoma with initial oral manifestation, presenting with the unusual features of gum hypertrophy and involvement of upper jaw and palate in a 10-year-old boy. This report discusses the clinical presentation, histopathologic and immunologic features, and diagnosis of this malignancy. %K Precursor T-ALL %K gum %K jaw %K oral cavity %U http://www.tjh.com.tr/jvi.asp?pdir=tjh&plng=eng&un=TJH-42714&look4=
