Burkitt's lymphoma (BL) cell lines estimated in a previous study as having a high, low and no tumourigenicity (7) were intravenously (i.v.) injected into preirradiated (480 rad) nude mice. BL cell lines with a high tumourigenic potential produced metastatic tumours in the brain, spinal cord, bone marrow, stomach and kidney, but did not disseminate into the lung, liver, ovary and spleen. The survival time of the tumour bearing animals ranged from 2 to 10 weeks. The majority of mice i.v. injected with highly tumourigenic BL cell lines showed paresis or paralysis of the hind legs. This was associated with the presence of neoplastic nodules either in the brain and/or in the spinal cord. In animals with metastasis to the stomach and kidney progressive cachexia was observed. The described experimental model of metastatic BL tumours in nude mice can effectively be used for the in vivo study of new therapeutic molecules such as monoclonal antibodies coupled or not to substances, toxic to tumour cells. This model can also be useful for the identification and analysis of homing properties of BL cells and their implication in BL pathogenesis.

A human Burkitt lymphoma (Daudi) has been grown in the mutant mouse called C.B-17 SCID. Twenty-eight days after s.c. injection of Daudi cells, a palpable tumor grew only at the site of injection in all injected mice. In contrast, after intravenous (i.v.) or intraperitoneal (i.p.) injection, macroscopic, disseminated tumors developed. Following i.v. inoculation, tumors grew in the lungs, kidneys, ovaries and adipose tissue, and microscopic tumor infiltrates were observed in the spleen, bone marrow, spinal column and femur, whereas after i.p. injection, the tumors were localized in the abdomen, liver, spleen, ovaries and muscular tunics of the gut, but did not disseminate into the lung or bone marrow. The growth pattern and phenotype of the Daudi cells were similar whether the inoculated tumor cells were derived from the in vitro cell line or from in vivo passaged tumors. The survival time of the tumor-bearing animals was dependent on the dose of i.v.-administered Daudi cells; as few as 100 cells caused death. All mice injected i.v. showed paresis or paralysis of the hind legs just prior to death. This was associated with the presence of neoplastic nodules within the spinal canal. Two surface antigens on Daudi cells (CD19 and CD22) were stably expressed in all the neoplastic lesions. Radiolabelled anti-CD22 antibodies localized in organs infiltrated with tumor, but did not penetrate primary s.c. tumors. This model of disseminated vs. solid tumor should prove useful for evaluating the efficacy of different types and doses of therapeutic antibodies, immunoconjugates and immunotoxins prepared from anti-human B-cell antibodies.

Cavernous sinus lymphoma is a rare occurrence. We report a case of a 37-year-old woman who was admitted for an oculo-motor paresis and retro-orbital pain. CT scan and MRI disclosed a cavernous sinus tumor. A surgical biopsy was performed through a pterional approach and the histological diagnosis was a solitary primary Burkitt's lymphoma. Aggressive chemotherapy led to a complete and asymptomatic remission after a follow-up of 9 years. The mechanism of the primary localization in the cavernous sinus is discussed.
