KSHV/HHV8-associated primary cutaneous plasmablastic lymphoma in a patient with Castleman's disease and Kaposi's sarcoma.

We report a unique case of Kaposi's sarcoma (KS)-associated herpesvirus (KSHV)/human herpesvirus (HHV)8-associated lymphoma in a 56-year-old man with a history of acquired immune deficiency syndrome, Castleman's disease, KS, and idiopathic thrombocytopenic purpura. Three months following the diagnosis of KS affecting a left cervical lymph node and Castleman's disease with bone marrow involvement, he presented with a subcutaneous, tender lesion on his left arm. A skin biopsy demonstrated a superficial and deep, interstitial-nodular infiltrate of severely atypical lymphoid cells showing plasmacytoid features, numerous mitotic figures, and frequent individual apoptotic tumor cells.
