Abstract
|
|
|
|
Cholesterol granuloma (CG) has been known to be a pathologic condition that is associated with many kinds of middle ear diseases. Histopathologically, it is characterized by foreign body giant cells and numerous clefts consistent with prior cholesterol crystals. It can occur in any pneumatized bone and can cause expansile changes in surrounding structures. The temporal bone is the most common site of CG, but presenting in the ear canal is rare. We report a case of CG in the external auditory canal with a review of literature.
