Abstract
Solitary neoplastic proliferation of plasma cells (plasmacytoma) rarely occurs in the central nervous system. The longest follow‐up in nine previously reported patients was 5 years. We have followed two patients with solitary intracranial plasmacytoma for 8 and 13 years, respectively. At the time of biopsy diagnosis, neither showed involvement of the adjacent calvarium or evidence of a systemic plasma cell dyscrasia. The first patient underwent partial excision of a mass in the right occipital lobe that showed no gross or microscopic involvement of the dura. The second patient had partial resection of a mass arising from dura and invading the left temporal lobe. Postoperative irradiation was given to both patients. No clinical or radiological sign of recurrent brain tumor has developed in either patient during the extended follow‐up period. Neither patient has had laboratory or clinical evidence of a systemic plasma cell dyscrasia. Solitary intracranial plasmacytoma may be a “curable” brain tumor.
