Treatment of metastatic sialoblastoma with chemotherapy and surgery.

Tumors of the salivary gland are very uncommon in children. Sialoblastoma is a rare, aggressive, blastomatous, and potentially malignant congenital tumor. Distant metastases are rare. We present a case of sialoblastoma with lung metastases that developed in a 4-year-old girl adjacent to a congenital nevus in the left cheek. The tumor was inoperable at diagnosis but the largest of the pulmonary metastases was removed surgically. The patient responded well to chemotherapy and underwent surgical excision of the primary tumor, followed by three more courses of chemotherapy.

Unusual mass in the parapharyngeal space: a Warthin's tumour.

Parapharyngeal space (PPS) tumours are uncommon and can be a diagnostic challenge as the presenting symptoms are often vague and non-specific. Most of the PPS tumours are salivary tumours (pleomorphic adenoma being the most frequent diagnosis), and are thought to originate from minor salivary glands or the deep lobe of the parotid gland. Warthin's tumour, another benign salivary tumour involving the PPS has been rarely reported. A case of bilateral, metachronous Warthin's tumour involving the PPS is reported here. PPS Warthin's tumour is a very rare condition that if undiagnosed may result in considerable morbidity.

Endoscopic stapling for pharyngeal pouch: does it make the cut?

BACKGROUND: Endoscopic stapling to treat pharyngeal pouch is a relatively new technique with the potential to reduce the morbidity associated with the open approach for pharyngeal pouch. Despite enthusiasm for the endoscopic approach there have been no series reported in Australia, and descriptions of outcomes and benefits are currently anecdotal. The aim of the present study was to determine the outcome associated with endoscopic stapling of pharyngeal pouch in an Australian setting. METHODS: All patients admitted for endoscopic stapling for a pharyngeal pouch between 1998 and 2002 by surgeons from the Adelaide and Flinders Universities were identified, and their medical records were reviewed for clinical and operative details. All patients were interviewed by telephone using a structured questionnaire to determine symptom resolution and patient satisfaction. The Likert scale was used to assess the impact of preoperative and postoperative symptoms upon quality of life. RESULTS: A total of 31 patients were identified. The mean age of the group was 75 years (range: 35-91 years) and half the patients had an American Society of Anesthesiologists physical status score of 3 or greater. In four patients the procedure was abandoned; (for three because of inability to pass the diverticuloscope and for one because the pouch was too small). Standard open surgery was undertaken in these patients. Of the 27 procedures completed endoscopically, interview follow up was obtained in 23, at a mean follow up of 17 months (range: 2-68 months). Outcome was very good or excellent in 21 (91%), with significant symptom resolution, reduction in Likert scores and high patient satisfaction. Three patients had previously had pouch surgery and endoscopic stapling was straightforward in these patients. Recurrence of a symptomatic pouch occurred in three patients. There was no significant morbidity related to the procedure. CONCLUSIONS: The early experience of endoscopic stapling for pharyngeal pouch in Adelaide is encouraging. The procedure achieves excellent control of symptoms and can be undertaken with minimal morbidity. Recurrence may be a problem, although repeat endoscopic stapling can be undertaken without difficulty.

Orbitofrontal cholesterol granuloma: percutaneous endoscopic-assisted curettage.

This paper describes the use of endoscopic visualization in curettage of orbital cholesterol granuloma (OCG). Two males aged 54 and 50 years presented with orbitofrontal cholesterol granulomas arising in the superolateral frontal bone and abutting the dura. The granulomas were approached via a superior eyelid crease incision and a 70 degree rigid endoscope was used to visualize curettage of the granuloma from the inner surface of the frontal bone and the dura. Both patients made an uncomplicated recovery and there was no recurrence at eight months and two years follow up. Percutaneous endoscopic curettage is an alternative to blind curettage, lateral orbitotomy or frontal craniotomy for OCG.
