title: Peripheral T-cell non-Hodgkin's lymphoma following treatment of nodular lymphocyte predominance Hodgkin's disease.
abstract: Previous reports have suggested that nodular lymphocyte predominance Hodgkin's disease (NLPHD) is a germinal center-derived B-cell lymphoma that is distinct from other types of Hodgkin's Disease. A relationship between NLPHD and simultaneous or subsequent development of large-cell (LC) non-Hodgkin's lymphoma (NHL) has been established. Both Reed-Sternberg cell variants in NLPHD and NHL cells in these cases express B-cell-associated antigens, and in some cases the B-cell lineage of the NHL has been confirmed by immunoglobulin gene rearrangement studies. The B-cell phenotype and the indolent course of both lymphomas suggest histologic progression of NLPHD to B-cell NHL, rather than a de novo LCNHL unrelated to Hodgkin's Disease. We report a unique case of T-large-cell lymphoma (TLCL) following successful chemotherapy of NLPHD. A 54-year-old male was treated with seven cycles of mechlorethamine, vincristine, procarbazine, prednisone chemotherapy for NLPHD and 4 years later developed recurrent adenopathy. Lymph node biopsy showed a diffuse LCNHL. Frozen section immunotyping and gene rearrangement studies confirmed the diagnosis of TLCL. To our knowledge, this case represents only the second report of TLCL associated with NLPHD and is of significance in that: (1) it demonstrates that T-cell neoplasia can occur in the setting of NLPHD; (2) this case does not appear to represent histologic progression of NLPHD and most likely represents de novo disease that may be secondary to chemotherapy; and (3) the clinical course may differ from the favorable prognosis seen in NLPHD associated with B-cell NHL.
