Metastatic Seminoma Simulating Malignant Lymphoma in an HIV Infected Hemophiliac

Abstract

Although most common, malignant lymphoma and Kaposi's sarcoma are not the only malignancies encountered in lymph nodes from HIV-infected patients. An increased frequency of testicular germ cell tumors in HIV-infected individuals has been reported. We report here the first case, to our knowledge, of a metastatic seminoma in an HIV-infected hemophiliac. The atypical clinical presentation, cervical and axillary adenopathy, simulated malignant lymphoma. The diagnosis was first suspected when a fine needle aspiration biopsy from an enlarged cervical node revealed a mixture of benign appearing lymphocytes and loosely cohesive large tumor cells in a “tigroid” background. Immunocytochemistry and a subsequent excisional biopsy confirmed the cytologic diagnosis. Metastatic germ cell tumors should be considered in the differential diagnosis of HIV-related lymphadenopathy.
