Orbital plasma cell tumours.

This paper reports two cases of orbital plasma cell tumours, one initially presenting as a localized lesion, but later developing dissemination and proving fatal within 7 months; the other presenting initially as a disseminated disease and apparently cured from that particular disease within 1 year, both on equivalent treatments. The importance of investigations for general disease (for therapeutic reasons) is emphasized as well as possibility of renal involvement and the unpredictability of the clinical course.
