Abstract
|
|
|
|
The clinical appearance of metastatic lesions without an obvious primary source for the tumor is not uncommon event although modern diagnostic technology has improved. Metastatic neoplasms of unknown primary origin account for up to 2.1-11% of metastatic lesions in temporal bones. We recently experienced a case with metastatic adenocarcinoma of unknown primary origin involving the temporal bone. A 66-year-old woman was admitted to our hospital because of facial palsy and facial pain. She was diagnosed with metastatic adenocarcinoma in the temporal bone based on the pathologic findings but the primary origin was not found despite extensive diagnostic work-up for all suspicious sites. So we report this case with a review of related literatures.
