Ph chromosome in a patient with non‐leukemic non‐hodgkin B‐cell lymphoma

Abstract
A standard Philadelphia translocation, t(9;22) (q34;q11), was found in lymph node cells from a patient with non‐leukemic non‐Hodgkin lymphoma at the time of diagnosis. The rearrangement of the breakpoint cluster region (bcr) was not detected with a bcr‐3′ probe. The neoplastic clone was of monoclonal B‐cell character with E‐, CD5‐, CD10‐, CD13‐, CD19+, CD20+, CD21+, CD25‐, HLA DR+, and positive surface lg(kappa). The patient showed no evidence of chronic myelogenous leukemia.
