Simultaneous occurrence of Kaposi's sarcoma and nodular lymphocyte predominant subtype of Hodgkin's lymphoma in the same lymph node.

Many cases have been established with coexisting Kaposi's sarcoma (KS) and classical Hodgkin's Lymphoma (C-HL) in the same lymph node. But composite presentation of KS and Nodular Lymphocyte Predominant subtype of Hodgkin's lymphoma (NLPHL) in the same lymph node has not been described yet. KS is related to immunodeficiency most frequently due to human immunodeficiency virus (HIV) infection or immunosupression by other reasons. Our case presented here was not related to any immunodeficiency status. Besides of being the first case of composite KS and NLPHL in the same lymph node, it was also unusual with the indolent behaviour of the NLPHL without any therapy for 8 years follow up and primary lymph node presentation of KS without cutaneous involvement.
