Recurrent respiratory papillomatosis : the Manchester experience, 1974-1992

A series of 59 patients of all ages with recurrent respiratory papillomatosis (RRP) treated over an 18-year period is presented. A number of these patients were initially diagnosed in childhood but required treatment throughout adult life. The frequency of laser treatment was not related to either disease duration or age at onset. In 28 patients, the HPV type was identified, showing that HPV type 11 was more common in children and ran a more protracted clinical course. The requirement for tracheostomy in this series was small, whereas the incidence of malignant change in adult patients was significant.

Metastatic renal cell carcinoma to the nose and paranasal sinuses

Renal cell carcinoma represents 3% of all malignant tumors. Metastatic deposits of renal cell carcinoma to the head and neck region are infrequent. The objective of this work is to analyze the clinical presentation, radiologic features, surgical and radiotherapy treatment, and outcome of metastatic renal cell carcinoma to the nose and sinuses.

Intralabyrinthine schwannoma shown by magnetic resonance imaging.

Intralabyrinthine schwannomas are rare benign tumours which present with progressive or fluctuant audiovestibular symptoms and may mimic Meniéres discase. The size and position of these lesions make preoperative diagnosis unusual and most are discovered incidentally at labyrinthectomy. A case is reported which was diagnosed on magnetic resonance imaging and confirmed at surgery.

Submandibular gland carcinoma; An audit of local control and survival following adjuvant radiotherapy

Carcinoma of the submandibular gland is a rare diagnosis, accounting for less than 2% of cases of salivary gland tumours. We have examined the treatment and outcome of a total of 30 patients treated with radiotherapy at the Christie Hospital, Manchester between 1980 and 1993. In most cases this followed radical surgery, though 12 patients were referred following either incomplete excision or biopsy only. Adenoid-cystic histology accounted for 19 cases (63%). Standard radiotherapy was delivered using a beam directed technique to treat the whole submandibular compartment. Doses prescribed were most commonly from 50 to 55 Gy in 16 fractions over three weeks. Cancer specific survival was 79% and 57% at 5 and 10 yr respectively, the continued fall at 10 yr reflected late recurrence seen in patients with adenoid-cystic histology. Local control was 85% and 73%, respectively. Nine of twelve patients with incomplete excision or biopsy only had local control with radiotherapy. Six patients developed lung metastases, all of whom had adenoid-cystic histology. Radiotherapy was well-tolerated acutely, and only one patient experienced osteoradionecrosis requiring surgical intervention. The incidence of adenoid-cystic carcinoma is higher in the submandibular than the parotid gland. This typically results in late recurrence, and a high incidence of lung metastases and this was confirmed in our study. However, overall survival was very similar to that of parotid carcinoma.

The diagnostic value of positron emission tomography (PET) with radiolabelled fluorodeoxyglucose (18F-FDG) in head and neck cancer.

Positron emission tomography (PET) scanning has recently been introduced into clinical practice but its usefulness in the management of head and neck cancer is not well defined. The aim of this prospective preliminary study was to examine the clinical value of fluorodeoxyglucose (FDG)--PET in patients with head and neck cancer treated by radiotherapy with surgery in reserve by (i) relating quantitative uptake of isotope to tumour type and histological grade and (ii) comparing the imaging findings of PET and magnetic resonance imaging (MRI) in post-radiotherapy assessment of tumour response. Twenty-one patients had pre-treatment PET and MRI scans and these were repeated four and eight months after treatment if there was no clinical relapse. Pre-treatment uptake of FDG using tumour to cerebellar ratio parameters was significantly related to the histological grade of squamous cancer (p = 0.04) but not to tumour type. Discordance of post-treatment PET/MRI findings in one case indicates a possible role for PET in the early detection of tumour recurrence. Other potential uses of PET scanning in the management of head and neck cancer are discussed.

Vomiting in pregnancy resulting in oesophageal perforation in a 15-year-old.

Spontaneous perforation of the oesophagus is extremely rare in children, as is perforation due to vomiting in pregnancy. We report the case of a 15-year-old in whom vomiting in early pregnancy resulted in oesophageal perforation with subcutaneous emphysema causing marked facial swelling in the absence of other signs. The more common clinical presentation of spontaneous oesophageal rupture (Boerhaaves syndrome) is discussed.

Severe radionecrosis of the temporal bone

Severe radionecrosis of the temporal bone is a potentially lethal condition which still occurs despite improvements in radiotherapy. A series of seven such cases is presented to outline the varied clinical features and management of this disease.

Localized tracheopathia osteoplastica of the subglottis

Tracheopathia osteoplastica is a benign dysplasia of the tracheobronchial tree which rarely presents clinical problems especially when localized. We present a case which caused an unexpected difficulty in intubation and was subsequently removed endoscopically using the CO2 laser.

Cerebellopontine angle lipoma

A case of a cerebellopontine angle lipoma is presented with a typical clinical, audiometric and radiological features of an acoustic neuroma. The correct pre-operative diagnosis was elusive even with the aid of magnetic resonance imaging.

External ear canal cholesteatoma. Case report.

External ear canal cholesteatoma is a rare condition in otologic practice. A case in a 43-year-old woman is presented in which despite the extensive nature of the lesion, minimal symptoms and absence of signs delayed diagnosis. The cause of the lesion and its treatment are discussed.
