To report a rare case of delayed endovascular coil extrusion following embolisation of a lingual artery pseudoaneurysm.

A 23-year-old woman presented with dysphagia and odynophagia 11 months after having experienced massive post-tonsillectomy haemorrhage. At that time, the bleeding had been stopped by embolisation of a lingual artery pseudoaneurysm and the external carotid artery. Clinical examination at admission showed extrusion of the embolisation coils in the lateral lower pharyngeal wall. The coils were removed under general anaesthesia in the presence of an interventional radiologist. The procedure and post-operative period were without complication and no bleeding was observed. The dysphagia and pain disappeared and the subsequent seven-month follow-up period was uneventful.

Although selective embolisation is a safe and effective treatment for severe post-tonsillectomy haemorrhage, the possibility of delayed coil extrusion should be kept in mind.

Cervical spine metastases account for 10 per cent of all spinal metastases. We report three cases of cervical spine metastases whose unusual primary presentation was with ENT-related symptoms.

The three patients reported herein did not have a confirmed diagnosis of malignancy at presentation. The first patient presented with stridor, the second presented with dysphagia and the third presented with dysphonia. All patients complained of significant neck pain that preceded and was concomitant to the other symptoms. Clinical suspicion of cervical spine involvement led to radiological investigation with computed tomography, which showed metastatic lesions in the craniovertebral junction and cervical spine region. Histological confirmation of malignancy was obtained for two of the three patients. The condition proved uniformly fatal in the weeks following diagnosis. A review of the literature on this condition was conducted using PubMed and Medline databases.

Cervical spine pathology may present initially to the ENT surgeon. A high degree of suspicion of cervical spine involvement should be maintained in elderly patients with persistent or progressive neck pain, with or without other ENT symptoms. Adequate radiological imaging will usually confirm the diagnosis.

To report two cases of laryngeal plasmablastic lymphoma, a rare and relatively recently described form of non-Hodgkin's lymphoma. It has not previously been described in the larynx, nor associated with upper airway obstruction.

We describe the clinicopathological features of two such cases in human immunodeficiency virus positive patients, and we discuss their unusual presentations and diagnostic features.

When evaluating a laryngeal tumour, plasmablastic lymphoma and other non-Hodgkin's lymphomata should be considered as differential diagnoses, particularly in the setting of a high prevalence of human immunodeficiency virus infection. Biopsy with detailed histopathological and immunohistochemical evaluation is recommended to ensure correct diagnosis and optimal management.

To explore the diagnosis and treatment of carcinosarcoma of the larynx.

Clinical information, including presentation, pathology, treatment and outcome, was obtained from a review of patient charts.

Seven male patients were confirmed pathologically to have had carcinosarcoma between 2003 and 2009 in our hospital. All patients underwent surgery: four total laryngectomies, two vertical partial laryngectomies, and one supracricoid partial laryngectomy-cricohyoidopexy. The mean follow up was 40.6 months. At the time of writing, six patients were alive and being followed; two of these suffered regional metastasis to the cervical lymphatic nodes and underwent radical neck dissection. One patient died of multiple distant metastases 60 months post-operatively.

Carcinosarcoma of the larynx describes a biphasic tumour showing both carcinomatous and sarcomatous differentiation. It is extraordinarily rare and prone to metastasise to the cervical lymph nodes. Complete surgical resection of laryngeal primary lesions with wide margins and suitable neck dissection of cervical nodes is reasonable therapy.

Parapharyngeal space tumours are uncommon and represent 0.5–1 per cent of all head and neck neoplasms; 20–30 per cent of these are malignant. Malignant peripheral nerve sheath tumours are rare and mostly encountered in patients with neurofibromatosis type 1. Only four cases of parapharyngeal space tumours have been reported in the English language in patients without neurofibromatosis type 1.

We report the case of a 64-year-old man with no stigmata of neurofibromatosis type 1, in whom a mass in the left pre-styloid region of the parapharyngeal space was an incidental finding following magnetic resonance imaging for investigation of cervical spine problems. The mass was consequently removed using a transcervical approach. A histological review revealed a low-grade malignant peripheral nerve sheath tumour.

We consider the pathophysiology of this highly malignant tumour as well as the challenging anatomy of the parapharyngeal space and the surgical and other therapeutic modalities utilised to treat this condition.
