Objective: We present a case report of a 55-year-old woman who had multiple recurrences with upward extension along the fallopian canal via the stylomastoid foramen. Results: Pleomorphic adenoma is the most common neoplasm of the parotid gland, and is associated with the risk of recurrence. The spread of parotid tumors into the temporal bone is uncommon. The tumor was found to be centered around the stylomastoid foramen, extending to the hypotympanum, infralabyrinthine cells, and close to the inferior wall of the internal auditory canal. Complete surgical resection of the recurrent tumor was performed by a subtotal petrosectomy with upper neck extension. Conclusion: The surgical approach should provide excellent visibility with a wide surgical exposure to secure local neurovascular structures. The existence of recurrent or metastasizing pleomorphic adenoma underscores the need for meticulous and complete surgical excision of the primary tumor, and close clinical follow-up.

Abstract

Objective: We present a case report of a 55-year-old woman who had multiple recurrences with upward extension along the fallopian canal via the stylomastoid foramen. Results: Pleomorphic adenoma is the most common neoplasm of the parotid gland, and is associated with the risk of recurrence. The spread of parotid tumors into the temporal bone is uncommon. The tumor was found to be centered around the stylomastoid foramen, extending to the hypotympanum, infralabyrinthine cells, and close to the inferior wall of the internal auditory canal. Complete surgical resection of the recurrent tumor was performed by a subtotal petrosectomy with upper neck extension. Conclusion: The surgical approach should provide excellent visibility with a wide surgical exposure to secure local neurovascular structures. The existence of recurrent or metastasizing pleomorphic adenoma underscores the need for meticulous and complete surgical excision of the primary tumor, and close clinical follow-up.
