Sellar plasmacytomas: a concise review.

The diagnosis of a sellar plasmacytoma is often missed and is mistaken for a non functioning pituitary adenoma. We reviewed the literature on reported cases of sellar plasmacytoma in order to identify its clinical presentation, laboratory, radiological and pathological characteristics. We describe the management of these cases after the correct diagnosis was made and provide insight to preoperative diagnosis of this entity. Preoperative diagnosis may help avoid unnecessary surgical resection of an otherwise radiosensitive tumor. We also report and describe in detail a new case of sellar plasmacytoma that we have recently evaluated.
