Abstract

Solitary plasmacytoma is a rare disorder comprising 5%-10% of all plasma cell neoplasms. Progression to multiple myeloma is the most common pattern of relapse. Appearance of new lesions without any systemic disease is the most unusual pattern of relapse seen in <2% cases. We present a case of a 46-year-old female who presented with features of third and seventh cranial nerve palsy, diagnosed with solitary plasmacytoma, with no evidence of any systemic disease. As per standard recommendations, the patient received radiotherapy to the local site. The patient developed relapse twice, at three sites, during the follow-up period. Investigations revealed no evidence of any systemic disease. In view of repeat relapses, the patient was started on immune modulatory agent. Two and half years after the last radiotherapy, the patient is symptom free with no evidence of any new lesion.

Keywords: haematology (incl blood transfusion); oncology; radiotherapy.
