Abstract

In this paper, we describe a case of nodular lymphocyte predominant Hodgkin lymphoma with the subsequent development of a peripheral T cell lymphoma. This case is unusual in that the sheets of atypical and small to intermediate-sized T cells in the diffuse component were CD8 positive and expressed cytotoxic proteins. The diagnosis of peripheral T cell lymphoma was supported by the demonstration of a clonal T cell receptor beta chain gene rearrangement by Southern blot analysis. Peripheral T cell lymphoma with a cytotoxic phenotype is a rare entity with an aggressive clinical behavior. As such, this report emphasizes the need to consider a diagnosis of coexisting peripheral T cell lymphoma in cases of nodular lymphocyte predominant Hodgkin lymphoma with atypical features, such as few or poorly defined B cell macronodules and diffuse T cell areas. The examination of both T cell receptor gamma and beta chain gene rearrangements should be performed to confirm such cases.
