Multiple Myeloma in a Young Female Presenting with Neurological Symptoms

Abstract EN

Background.

Multiple myeloma is overall the 14th most common malignancy but is rarely seen in those younger than 35 years.

Those in the younger age group have been shown to have a more aggressive course but reportedly have had similar responses to treatment compared to older cohorts.

Extramedullary plasmacytomas are discrete soft tissue masses of neoplastic monoclonal plasma cells that often occur in patients with multiple myeloma.

Case.

This case entails a young female with new diagnosis of multiple myeloma and multiple extramedullary plasmacytomas presenting with neurological symptoms.

She was treated with CyBorD regimen but was refractory and progressed.

Treatment was changed to DCEP regimen, and daratumumab was added for primary refractory myeloma.

The patient improved rapidly.

Conclusion.

This is a unique case of multiple myeloma in a young female that had failed first-line treatment but responded to targeted therapy of daratumumab.

It highlights that multiple myeloma may present atypically in young patients.

More research is needed on appropriate initial diagnosis and treatment of patients in this age group.
