Intermediate and highly malignant non-Hodgkin and primary central nervous system lymphomas are marker diseases for AIDS. Cavum and oropharynx involvement by these tumors is uncommon. Although there are few cases reported in the literature, these may be primary localizations of the tumor. We present a hemophilic HIV+ patient with non-Hodgkin lymphoma of the cavum. The histologic diagnosis was high-grade, pleomorphic, centroblastic lymphoma. The patient was treated with chemotherapy plus intrathecal chemotherapy and highly active antiretroviral therapy (HAART). His evolution has been excellent. One year after diagnosis, the patient is asymptomatic with no evidence of residual tumor, and responding well to HAART.

RESUMO
A total of 32 cases of tarsometatarsal fracture dislocations, treated during a 15-year period, have been retrospectively reviewed. Results were assessed in 29 patients with a mean age of 33.8 years and a mean follow-up of 6.3 years. On the basis of Quénu and Küss' classification, five patients had homolateral dislocations, three had divergent dislocations, and 21 had partial dislocations (seven medial partial and 14 lateral partial). Treatment included closed manipulative reduction, occasionally followed by Kirschner (K)-wire fixation. If closed reduction was not achieved, open reduction was performed. Results were assessed according to Hardcastle's scoring system. On that basis, 20 good, 5 fair, and 3 poor results were obtained and there was one early amputation. Good results were associated with an accurate reduction. Open treatment is advocated if minor displacement persists. Routine K-wire fixation is advised for all cases.

Serologic reactivity against EBV-infected lines was assayed in patients with AIDS (n = 4) or the AIDS related complex (AIDS-RC) (n = 46) residing in Argentina. Anti-VCA serology was comparable to that of controls. However sera from AIDS and AIDS-RC could induce antibody dependent cell mediated cytotoxicity (ADCC) to EBV-infected cell lines (P3HRIK and Raji). ADCC activity could be recovered in the high molecular weight fractions of AIDS and AIDS-RC sera. ADCC was observed in sera with high levels of PEG precipitable material (PEG-pp) but was unrelated to the presence of complement-fixing immune complexes (Clq-F) or to anti-VCA titers. Fc receptor (FcR) bridging between target cells FcR and effector cells FcR may play a role in the outcome of total ADCC.
