A 72-year-old man with a 2-year history of motor-sensory neuropathy of the right foot was found to have a lymphoma involving a 50-cm length of the sciatic nerve. This occurred in the absence of any other evidence of disease by detailed clinical staging. The lymphoma was of large follicular center-cell type. The cells strongly expressed a B-cell marker detected by the 4KB5 monoclonal antibody and selectively infiltrated the nerve bundles, dissociating preexisting myelin-producing Schwann cells and axons. This is the second report of similar localization. Primary selective involvement of a nerve is a rare mechanism of peripheral neuropathy in lymphoproliferative disorders, to be added to systemic dissemination of lymphomas and leukemias, direct spread of an adjacent tumor, and immunologically mediated disease.

An analysis is presented of a comparative study of the Delta T and Copper T 200 IUDs. A total of 195 postabortion insertions was performed between March 1981 and August 1982. All insertions were performed with an inserter. Primary bleeding/pain complaints after insertion were largely related to intermenstrual problems, with spotting the most frequently reported. Nine women had their devices removed for PID. One pregnancy occurred at ten months in the Delta T group. Both groups had one expulsion/displacement. Eight devices in each group were removed for bleeding/pain. Two women in the TCu group had their devices removed for personal reasons. The 6-months continuation rates for the two groups were 85.5 for the Delta T group and 82.2 for the TCu group. The 6-months follow-up rate for the Delta T group was 39.4 and 38.8 for the TCu group.
