Clinics and Pathology


B- and T-cell lymphomas and chronic lymhocytic leukemia (CLL).

Phenotype stem cell origin

39 lymphoma cases to date; among them, lymphomas with B-cell phenotype in 26 patients: follicular lymphoma (FL, n=6) (Rosenwald et al 1999; Horsman et al 2001; Goodlad et al 2003; Fan & Rizkalla 2003; Rajgopal et al 2003; Aamot et al 2007), diffuse large B-cell lymphomas (DLBCL, n=6) (Koduru et al., 1987; Konishi et al., 1990; Cigudosa et al., 1999; Cerretini et al., 2006; Niitsu et al., 2009; Niitsu et al., 2009); mature B-cell neoplasm (n=3, MBCN) ( Maseki et al., 1987; Coignet et al., 1996; Cook et al., 2004), nodal marginal zone B-cell lymphoma (NMZL, n=3) ( Cook et al., 2004; Aamot et al., 2005; Martin-Subero et al., 2007); splenic marginal zone B-cell lymphoma (SMZL, n=3) (Dierlamm et al., 1996; Le Baccon et al., 2001; Narayan et al., 2013), Hodgkin disease (HD, n=3) (Dennis et al., 1989; Schlegelberger et al., 1994; Falzetti et al., 1999), 1 post-transplant lymphoproliferative disorder with primary non-Hodgkin lymphoma (Djokic et al., 2006) and 1 mantle cell lymphoma case (Siebert et al., 1998).

14 males and 25 females with various forms of lymphomas (aged 16 to 89 years; median age 62 years); median age was 62 years in B-cell lymphomas (11 males and 15 females aged 16 to 89 years); female prevalence in T-cell malignancies (3 males, 10 females aged 32 to 78 years). Similarly, there is a female prevalence in chronic lymphocytic leukemia patients (3 males and 13 females), aged 40 to 79 years (from the known data).


Unknown, due to the heterogeneity of diseases; (indolent versus aggressive disease); patients with only numerical abnormalities may have better outcome than patients with structural changes in a sideline.

Genes Involved and Proteins

Whole chromosome gain of an X chromosome has been described in various types of hematological malignancies, including malignant lymphomas. Additional sex chromosomes are usually part of complex karyotypes, representing secondary karyotypic alterations in a significant proportion of lymphomas, and less frequently in CLL. While extra X chromosome is a known numerical abnormality in these diseases, its gain as the sole acquired abnormality is not a common feature. Numerical X chromosome changes are often found in a sideline, indicative of a multistep pathogenesis, where X chromosome gain would likely represent a relatively early genetic event. However, it is unclear whether +X alone is capable of promoting oncogenesis or aberrant effects of the trisomy might allow direct acquisition of cancer-promoting mutations.
