[A Japanese case of human herpes virus-8-associated multicentric castleman disease complicated by hemophagocytic syndrome].

We report a Japanese case of human herpes virus-8 (HHV-8)-associated multicentric Castleman disease(MCD) complicated by hemophagocytic syndrome(HPS). A 60-year-old man presented with persistent fever and progressive pancytopenia in June 2004. On physical examination, anemia, icterus, hepatosplenomegaly, and generalized lymphadenopathy were detected.

Adult T-cell leukemia/lymphoma with multiple integration of HTLV-1 provirus presenting as an isolated paranasal sinus tumor: a case report.

Background: Adult T-cell leukemia/lymphoma (ATLL) is a highly aggressive T-cell lymphoma and etiologically associated with human T-lymphotropic virus type 1 (HTLV-1). Patients with ATLL commonly present with leukemic changes, systemic lymphadenopathy, and/or extranodal lesion and have very poor prognosis.

Methods And Results: We describe a rare case of ATLL presenting as an isolated paranasal mass.
