Abstract

Plasmacytoma is a monoclonal neoplastic proliferation of plasma cells derived from bone marrow. Plasmacytoma of the skull base is very rare. Recently, the authors experienced a case of a 50-year-old woman with a tumor like lesion originating from the right sphenoid bone. The patient presented with a 3-month history of right facial pain and paresthesia. She had been diagnosed and treated with multiple myeloma for more than 5 years, although she was in complete remission until recently. Imaging studies including contrast CT scan and MRI, showed a huge, enhanced and irregular shaped lesion in the sphenoid bone along with skull base destruction and intracranial invasion. The patient underwent transnasal endoscopic biopsy under local anesthesia. The pathology was consistent with a plasma cell tumor and it was confirmed as a solitary plasmacytoma of the bone of the skull base. We report this rare case along with a literature review.
