Subsets of non-Hodgkin's lymphoma in humans have been shown to involve activation of protooncogenes such as MYC and BCL2 resulting from chromosome translocation involving the IGH and TCR genes. Malignant lymphomas in the canine present histologic and clinical subsets similar to those in humans. To study the genetic nature of these lymphomas, we undertook this study to determine, by Southern blotting analysis, the extent of homology between the human and canine genes MYC, BCL2, IGH, and TCRB using human gene probes. Our results, presented here, show that the organization of these genes in the two species is very similar.

Castleman's disease (CD) is thought to be related with an initially benign viral disease with cytokine-driven propagation and malignant transformation. This paper reports the first case of a simultaneous discordant lymphoma consisting of lymphocyte-depleted classical Hodgkin's lymphoma (LDCHL) and peripheral T-cell lymphoma (PTCL) arising in a patient with multicentric CD (MCD). PTCL occurred 4 years after the diagnosis of MCD, and LDCHL was developed 6 years after the treatment of PTCL, sequentially. The following year, the patient presented with a relapse of a simultaneous discordant lymphoma. On excisional cervical LN biopsy, immunohistochemical stain pattern was identical with previously diagnosed LDCHL, which expressed CD30, CD15, PAX5, and Epstein-Barr virus (EBV)-encoded RNA. PTCL was positive for CD3, CD4, CD5, CD10, and CD56, and showed identical TCRB and TCRG gene rearrangements to those detected initially. MCD was thought to be the major contributing factor leading to initial PTCL, while EBV-positive LDCHL is thought to have promoted the development of PTCL, as a persistently abnormal immune microenvironment may induce the recurrence of PTCL. MCD runs a more aggressive course and can progress to Hodgkin's lymphoma (HL), non-Hodgkin's lymphoma (NHL), or combined HL/NHL. Due to its malignant potential, prompt recognition and therapy is critical for these situations, which may be life threatening.
