Abstract:
Intraductal carcinomas are rare, malignant tumors that arise from the salivary glands. They commonly grow from the parotid gland and no cases growing from the parapharyngeal space have been reported to date. We report a 76-year-old man who was inadvertently found to have a parapharyngeal lesion by CT scans and MR imaging. The tumor was resected through an upper neck approach and diagnosed histopathologically as intraductal carcinoma. As far as we are aware, this is the first case of intraductal carcinoma arising from the parapharyngeal space. Here, we describe the management of this disease together with a review of the relevant literature.
