Abstract

Background. Middle-ear carcinoid tumour is a rare malignant tumour with an indolent course occasionally causing regional or distant metastasis. This paper presents a case of middle-ear carcinoid tumour metastasising to the parapharyngeal space and the parotid gland 20 years after the first surgery.

Case report. A 35-year-old woman who underwent multiple tympanomastoidectomies for middle-ear carcinoid presented with tumours of both the parapharyngeal space and parotid gland, detected by regular imaging. Based on the clinical course, metastatic relapse of middle-ear carcinoid was suspected. This was treated with subtotal parotidectomy with elective neck dissection (levels II and III), leading to the pathological diagnosis of carcinoid tumour. A cervico-parotid approach was selected to avoid complications associated with parapharyngeal space tumour removal. Transient facial palsy (House–Brackmann grade III) occurred, which completely recovered two months after surgery.

Conclusion. Awareness of parapharyngeal space tumours possibly caused by metastasis from a middle-ear tumour is necessary.
