A clinical diagnosis of parotid tumour was made. Cytology revealed to be a benign parotid tumour. Since the mass was large in size and patient was a child, a computed tomography (CT) scan was advised. CT scan suggested a well?defined, lobulated, homogeneous, mildly enhancing soft tissue lesion with loss of interface with the masseter muscle and multiple small lymph nodes.
A provisional diagnosis of pleomorphic adenoma was made, and superficial parotidectomy planned. Anterior dissection the tumour was found to originate from the buccal and zygomatic branches of the facial nerve. The mass was removed successfully with careful dissection.The gross appearance of the tumour was like a brain tissue histopathologically, it was confirmed to be an intraparotid shwannoma.
