Abstract
|
|
|
|
Extramedullary plasmacytoma is a non-epithelial neoplasm of plasma cell origin that does not accompany a systemic spread. Only a few cases of this disease developed in the temporal bone have been reported so far. This case report describes an unusual case of solitary extramedullary plasmacytoma of the temporal bone that mimicked a large jugular foramen tumor with hypoglossal canal involvement. The tumor was diagnosed by a biopsy from the external auditory canal at the outpatient clinic, and effectively controlled with primary radiotherapy. Based on our experience, when a jugular foramen tumor is suspected, such as in the case of extramedullary plasmacytoma, a biopsy for pathologic investigation should be considered whenever necessary in order to distinguish lesions that may not require nonsurgical treatment.
