Identity

ICD-Topo C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS
ICD-Morpho 9811/3 B lymphoblastic leukaemia/lymphoma, NOS
Atlas_Id 1319
Note the 2 translocations t(1;14)(q21;q32) and t(1;22) are variants of each other
This t(1;14)(q21;q32) with BCL9 involvement is different from the t(1;14)(q21;q32) with FCGR2B involvement, from the t(1;14)(q21;q32) with MUC1 involvement and from the t(1;14)(q21;q32) with IRTA1 involvement.

Clinics and Pathology

Disease Acute lymphoblastic leukemia (ALL) and non Hodgkin lymphoma (NHL)
Epidemiology a case of ALL in a 30 yr old male patient, a case of follicular NHL in a 57 yr old female patient, and a case of mantle cell lymphoma in a 87 yr old female patient
Prognosis prognosis was poor in 2 cases

Cytogenetics

Cytogenetics Morphological There was a t(14;18)(q32;q21) and a complex karyotype in the follicular NHL caset, and a t(11;14)(q13;q32) and a complex karyotype in the case of mantle cell lymphoma case
